The way to Extend the working life of Conveyor Belt

conveyor belt

1. Idler groove angle

The larger the groove angle is, the more longitudinal wrinkles and bends are easy to appear on the conveyor belt, and the irregular longitudinal pressure crosses the conveyor belt. Therefore, the groove angle shall be minimized to the lowest available position, and this fatigue factor shall be avoided at all times.

2. Idler clearance at grooving point

The wrinkle of the conveyor belt at the grooving point may be a sign that the idler is installed too far away, and the gap between the center roller and the edge roller is too large. The width can also cause the conveyor belt to squeeze inward and fatigue. It is recommended that the maximum clearance between the center roller and the edge roller is 10mm.

3. Maintenance of idler

In many cases, the importance of roller maintenance cannot be paid attention to. Dirty or lack of lubrication rollers may increase power costs and Serious problems with the conveyor belt. This phenomenon is common in the working conditions of increasing belt speed and shortening maintenance time, especially when the belt speed is high and the belt weight adopts pin shaped idler, the middle flat idler is easy to be damaged. Blocked idlers or idlers with broken bearings are the cause of friction heat and may be a potential ignition cause of conveyor belts or other materials.

4. different grooving idler heights

When one idler is higher than the adjacent one, the conveyor belt will bend excessively at that point, and the load on the idler is relatively high, the conveyor belt may have two problems: traces and core fatigue.

5. transition distance

The distance between the flat or bulging roller at the head and tail of the conveyor and the – first fully grooved idler device must be large enough to avoid excessive pressure, especially the special tension at the edge of the conveyor belt and the pressure in the middle of the conveyor belt. The short distance of the transition section will significantly shorten the service life of the conveyor belt and minimize these pressure results. The conveyor belt can be gradually bent to the final angle by using idler rollers with different grooving angles. Similarly, the height indicated by the roll profile associated with the first idler device is critical.

6. Convex surfaces and vertices

When the conveyor is installed, if there is a convex curved surface on the ground, its radius is too small, which may lead to conveyor belt fatigue, which is similar to that caused by an irregular idler. The fatigue condition of the conveyor belt caused by degree is similar. The surface should be as flat and gradual as possible. Additional idlers at lower slopes also help to equalize the additional pressure generated as much as possible. At the apex, lowering the groove angle helps to reduce the pressure on the edge of the conveyor belt

7. Concave surface

When the conveyor is installed, if there is a concave curved surface on the ground, its radius should be large enough to prevent the bending of the edge of the conveyor belt. When the conveyor belt is full. During loading, the distance between idlers keeps the sagging of the conveyor belt to a minimum. As with convex surfaces, idlers should be placed in radians to help the belt drive across the surface. It is very important that the radius of the curved surface is large enough and the conveyor belt is heavy enough. It enables the conveyor belt to be carried by the middle idler at any time and forms the track of the conveyor belt in this part.

8. Loading point

The damage of conveyor belt during the service period mostly occurs in this area

8.1 The basic element is to ensure that when the load is sent to the conveyor belt, it runs in the same direction and at the same speed as the conveyor belt, the free fall of the load is as low as possible, and the residence time on the conveyor belt is as short as possible, otherwise it will cause the material to move on the conveyor belt and cause Scratch and wear. If the falling height is too high, it will unnecessarily impact the core of the conveyor belt.

8.2 It is also important that the load must be unloaded to the center of the conveyor belt to avoid deviation failure. Cracks and irregular grinding on the idler

8.3 Larger materials shall be refined before being sent to the conveyor, and then flow evenly to the conveyor through the buffer of the chute, which can prevent the conveyor belt from wearing belt core damage, and stable loading.

8.4 Buffer idlers are usually used under the loading area to help reduce the impact damage of the belt core.

8.5 The side baffle is used to help the load centripetal, but it is not allowed to wear the conveyor belt covering or intercept materials between it and the conveyor belt.

9. Conveyor belt cleaner

These sweepers are usually placed behind or on the unloading roll. Regular maintenance of them is necessary to avoid the impact of the scraper on conveying. The damage of the belt and the return of materials at the return idler cause the damage and deviation of the conveyor belt.

Conveyor belt cleaner manufacturer may also make suggestions on installation and maintenance.

10. Mechanical / vulcanized joints

As has been explained above, it is crucial to minimize the stress on the conveyor belt and maximize the service life of the conveyor belt. The maintenance of the project is necessary, and the avoidance of these unwanted stresses is even more important than the completed joint life. Under normal conditions, in order to maximize the service life of the joint and provide a safe environment, all the following items should be avoided.

Exemption:

Improper installation of scraper

Idler damaged

Incorrect idler

Poor grooving point

Unreasonable grooving

Irregular stress

11. Maintenance of steel wire rope core conveyor belt

Steel cord conveyor belt is mainly used for high speed Large traffic volume Long distance transportation. In use, the steel wire rope core conveyor belt is the same as other conveyor belts. There is no fundamental difference, but the elongation of the steel wire rope core conveyor belt is small, which is an advantage, but the disadvantage is that the steel wire rope core is easy to break. Therefore, when using a wire rope core conveyor belt, pay attention to:

11.1 Prevent materials from getting stuck and damaging the conveyor belt

Due to the problems of material shape, safety system, and service conditions, the material is likely to fall between the roller and the conveyor belt. The belt cannot meet the elongation requirements, resulting in damage and penetration of the conveyor belt. According to the experiment, if the 20-30mm material is stuck between the conveyor belt and the roll Jane, the conveyor belt may be damaged. The most easily jammed part is at the tail, where a scraper must be added, especially the inclined conveyor. In order to prevent material overflow, a deck plate can be added under the bearing conveyor belt and a baffle plate can be added above the bearing conveyor belt The length of the baffle plate is equivalent to 4 times the bandwidth, and the table panel is 4 ~ 5m longer than the baffle plate.

11.2 The idler spacing and groove angle of the convex and concave points of the conveyor shall be adjusted properly

Because in the convex part, the center tension of the conveyor belt is small, while the stress on both sides is large. The larger the groove angle is, the greater the stress on both sides is. Therefore, when installing the idler, the tension at the concave convex position shall be determined according to the curvature of the idler.

11.3 Cleaning conveyor belt

During the operation of the conveyor belt, fine material particles will drill into the surface of the conveyor belt and accumulate on the guide roller and return idler. The diameter of the idler increases and the conveyor belt appears irregular bending. In order to prevent this, the surface of the conveyor belt must be cleaned.

11.4 Prevent the impact of large materials

Large materials falling directly onto the conveyor belt will damage the belt surface and cause core fatigue. In serious cases, the conveyor belt will be cut off. In case of such accidents, the chute drop shall be reduced to make the material flow speed and the conveyor belt speed- To, chute direction, and conveyor belt running direction agreement. At the same time, various feeders can be installed or chute with buffer, and special baffle leakage can be used to prevent conveyor belt damage.

Trudeau’s Gun Grab Could Cost Taxpayers a Whopping $7 Billion

Trudeau's Gun Grab
Trudeau plans to purchase 2,063 firearm from legal gun owners in Canada - Rebel News Image

A recent report indicates that since Trudeau’s announcement of his gun buyback program four years ago, almost none of the banned firearms have been surrendered.

The federal government plans to purchase 2,063 firearm models from retailers following the enactment of Bill C-21, which amends various Acts and introduces certain consequential changes related to firearms. It was granted royal assent on December 15 of last year.

This ban immediately criminalized the actions of federally-licensed firearms owners regarding the purchase, sale, transportation, importation, exportation, or use of hundreds of thousands of rifles and shotguns that were previously legal.

The gun ban focused on what it termed ‘assault-style weapons,’ which are, in reality, traditional semi-automatic rifles and shotguns that have enjoyed popularity among hunters and sport shooters for over a century.

In May 2020, the federal government enacted an Order-in-Council that prohibited 1,500 types of “assault-style” firearms and outlined specific components of the newly banned firearms. Property owners must adhere to the law by October 2023.

Trudeau’s Buyback Hasn’t Happened

“In the announcement regarding the ban, the prime minister stated that the government would seize the prohibited firearms, assuring that their lawful owners would be ‘grandfathered’ or compensated fairly.” “That hasn’t happened,” criminologist Gary Mauser told Rebel News.

Mauser projected expenses ranging from $2.6 billion to $6.7 billion. The figure reflects the compensation costs amounting to $756 million, as outlined by the Parliamentary Budget Office (PBO).

“The projected expenses for gathering the illegal firearms are estimated to range from $1.6 billion to $7 billion.” “This range estimate increases to between $2.647 billion and $7 billion when compensation costs to owners are factored in,” Mauser stated.

Figures requested by Conservative MP Shannon Stubbs concerning firearms prohibited due to the May 1, 2020 Order In Council reveal that $72 million has been allocated to the firearm “buyback” program, yet not a single firearm has been confiscated to date.

In a recent revelation, Public Safety Canada disclosed that the federal government allocated a staggering $41,094,556, as prompted by an order paper question from Conservative Senator Don Plett last September, yet yielded no tangible outcomes.

An internal memo from late 2019 revealed that the Liberals projected their politically motivated harassment would incur a cost of $1.8 billion.

Enforcement efforts Questioned

By December 2023, estimates from TheGunBlog.ca indicate that the Liberals and RCMP had incurred or were responsible for approximately $30 million in personnel expenses related to the enforcement efforts. The union representing the police service previously stated that the effort to confiscate firearms is a “misdirected effort” aimed at ensuring public safety.

“This action diverts crucial personnel, resources, and funding from tackling the more pressing and escalating issue of criminal use of illegal firearms,” stated the National Police Federation (NPF).

The Canadian Sporting Arms & Ammunition Association (CSAAA), representing firearms retailers, has stated it will have “zero involvement” in the confiscation of these firearms. Even Canada Post held back from providing assistance due to safety concerns.

The consultant previously assessed that retailers are sitting on almost $1 billion worth of inventory that cannot be sold or returned to suppliers because of the Order-In-Council.

“Despite the ongoing confusion surrounding the ban, after four years, we ought to be able to address one crucial question.” Has the prohibition enhanced safety for Canadians? Mauser asks.

Illegally Obtained Firearms are the Problem

Statistics Canada reports a 10% increase in firearm-related violent crime between 2020 and 2022, rising from 12,614 incidents to 13,937 incidents. In that timeframe, the incidence of firearm-related violent crime increased from 33.7 incidents per 100,000 population in 2021 to 36.7 incidents the subsequent year.

“This marks the highest rate documented since the collection of comparable data began in 2009,” the criminologist explains.

Supplementary DataData indicates that firearm homicides have risen since 2020. “The issue lies not with lawfully-held firearms,” Mauser stated.

Firearms that have been banned under the Order-in-Council continue to be securely stored in the safes of their lawful owners. The individuals underwent a thorough vetting process by the RCMP and are subject to nightly monitoring to ensure there are no infractions that could pose a risk to public safety.

“The firearms involved in homicides were seldom legally owned weapons wielded by their rightful owners,” Mauser continues. The number of offenses linked to organized crime has surged from 4,810 in 2016 to a staggering 13,056 in 2020.

“If those in power … aim to diminish crime and enhance public safety, they ought to implement strategies that effectively focus on offenders and utilize our limited tax resources judiciously to reach these objectives,” he stated.

Viktor Bout, the infamous Russian arms dealer who was exchanged two years ago for Brittney Griner by President Biden, has reportedly returned to arms trading, as detailed in a report by the Wall Street Journal.

The Wall Street Journal has revealed that Vikto Bout, infamously dubbed the “merchant of death,” is seeking to facilitate the sale of small arms to the Houthis. A report indicates that Houthi representatives met with Bout in Moscow in August to discuss the acquisition of $10 million in automatic weapons.

Nonetheless, the anticipated arms deal remains unfulfilled, as indicated by the report.

Reports indicate that the weapons being discussed do not encompass larger systems such as anti-ship or anti-air missiles, which could represent a considerable risk to U.S. military operations in the area.

Requests for comment from the WSJ regarding Bout’s alleged involvement in the arms trade went unanswered by the Kremlin and Russia’s Ministry of Defense. Steve Zissou, an attorney who provided legal representation for Bout during his time in U.S. custody, refrained from commenting on the possibility of Bout’s meetings with the Houthis.

Viktor Bout released in 2022

Bout, who became affiliated with Russia’s Kremlin-loyal Liberal Democratic Party following his release in a prisoner swap in December 2022, has kept a low profile since his return.

Bout was taken into custody in Thailand in 2008 and subsequently extradited to the United States, where he faced conviction in 2012 on charges associated with arms trafficking, resulting in a 25-year prison sentence.

For almost twenty years, Bout stood out as one of the globe’s most notorious arms dealers, providing weaponry to unrecognized governments and insurgent factions throughout Africa, Asia, and South America. The activities he conducted served as the basis for the 2005 film Lord of War.

Even after his conviction and imprisonment, reports indicate that Bout’s network persisted in its operations, contributing to conflicts in some of the globe’s most perilous areas.

PepsiCo Reduces Revenue Projections As North American Snacks And Key International Markets Underperform.

Pepsi

(VOR News) – In the third quarter of this year, Pepsi’s net income was $2.93 billion, which is equivalent to $2.13 per share. This was attributed to the company.

This is in stark contrast to net income of $3.09 billion, which is equivalent to $2.24 per share, during the same period in the previous year. The company’s earnings per share were $2.31 when expenses were excluded.

Net sales decreased by 0.6%, totaling $23.32 billion. Organic sales increased by 1.3% during the quarter when the effects of acquisitions, divestitures, and currency changes are excluded.

Pepsi’s beverage sales fell this quarter.

The most recent report indicates that the beverage and food sectors of the organization experienced a 2% decline in volume. Consumers of all income levels are demonstrating a change in their purchasing habits, as indicated by CEOs’ statements from the previous quarter.

Pepsi’s entire volume was adversely affected by the lackluster demand they encountered in North America. An increasing number of Americans are becoming more frugal, reducing the number of snacks they ingest, and reducing the number of times they purchase at convenience stores.

Furthermore, Laguarta observed that the increase in sales was partially attributed to the election that occurred in Mexico during the month of June.

The most significant decrease in volume was experienced by Quaker Foods North America, which was 13%. In December, the company announced its initial recall in response to a potential salmonella infection.

Due to the probability of an illness, the recall was extended in January. Pepsi officially closed a plant that was implicated in the recalls in June, despite the fact that manufacturing had already been halted.

Jamie Caulfield, the Chief Financial Officer of Pepsi and Laguarta, has indicated that the recalls are beginning to have a lessening effect.

Frito-Lay experienced a 1.5% decline in volume in North America. The company has been striving to improve the value it offers to consumers and the accessibility of its snack line, which includes SunChips, Cheetos, and Stacy’s pita chips, in the retail establishments where it is sold.

Despite the fact that the category as a whole has slowed down in comparison to the results of previous years, the level of activity within the division is progressively increasing.

Pepsi executives issued a statement in which they stated that “Salty and savory snacks have underperformed year-to-date after outperforming packaged food categories in previous years.”

Pepsi will spend more on Doritos and Tostitos in the fall and winter before football season.

The company is currently promoting incentive packets for Tostitos and Ruffles, which contain twenty percent more chips than the standard package.

Pepsi is expanding its product line in order to more effectively target individuals who are health-conscious. The business announced its intention to acquire Siete Foods for a total of $1.2 billion approximately one week ago. The restaurant serves Mexican-American cuisine, which is typically modified to meet the dietary needs of a diverse clientele.

The beverage segment of Pepsi in North America experienced a three percent decrease in volume. Despite the fact that the demand for energy drinks, such as Pepsi’s Rockstar, has decreased as a result of consumers visiting convenience stores, the sales of well-known brands such as Gatorade and Pepsi have seen an increase throughout the quarter.

Laguarta expressed his opinion to the analysts during the company’s conference call, asserting, “I am of the opinion that it is a component of the economic cycle that we are currently experiencing, and that it will reverse itself in the future, once consumers feel better.”

Additionally, it has been noted that the food and beverage markets of South Asia, the Middle East, Latin America, and Africa have experienced a decline in sales volume. The company cut its forecast for organic revenue for the entire year on Tuesday due to the business’s second consecutive quarter of lower-than-anticipated sales.

The company’s performance during the quarter was adversely affected by the Quaker Foods North America recalls, the decrease in demand in the United States, and the interruptions that occurred in specific international markets, as per the statements made by Chief Executive Officer Ramon Laguarta.

Pepsi has revised its forecast for organic sales in 2024, shifting from a 4% growth rate to a low single-digit growth rate. The company reiterated its expectation that the core constant currency profitability per share will increase by a minimum of 8% in comparison to the previous year.

The company’s shares declined by less than one percent during premarket trading. The following discrepancies between the company’s report and the projections of Wall Street were identified by LSEG in a survey of analysts:
