Dec 05, 2004· I am revising some old maintenance strategies for this site. One of these is conveyor idler maintenance. Our trunk conveyors, some 4km of them, run at over 5m/s. We currently use steel rollers as troughing idlers and return idlers. These currently are run to failure and appear to last about 3 years before the bearings give up. Every week there are about 30 50 odd rollers identified for ...
Conveyor Carrying Roller Application. Carrying roller is an important component for light to heavy industry bulk material handling equipment, such as overland conveyors, coalconveyors, highspeed trough belt conveyor system projects, crushing and screening. These equipment are widely used in coal and lignite mining, cement, quarries, tunneling,
Conveyor design capacity is based on both the coal density and the angle of surcharge, which is the angle to the horizontal that the surface of the coal assumes while at rest on a moving conveyor ...
A major expansion at a gold mine included an innovative idler design developed by Martin Engineering in conveyor transfer areas. The mine's highcapacity conveyor system faces continuous loads and heavy impact from 8inch lumps of copper ore. To withstand this impact, Martin Engineering designed a special belt support system.
Some people use one 20 degree idler at each end of a 35 degree conveyor, and 20 degree and 35 degree idlers on each end of a 45 degree conveyor. The object of this approach is to have the rolls sloped to suit the belt contour between the last regular or impact idler and the adjacent pulley.
CONDITION MONITORING for CONVEYORS A TOOL for INCREASED PRODUCTIVITY SYNOPSIS A stoppage in the conveyor transport system means no production in most mining applications. Whether the stoppage is due to a minor problem or a major problem, the effect is the same. In the coal industry with conveyors carrying between 1,000 and 3,500 tonnes per hour ...

May 06, 2012· The local idler standard, SABS 1313 1980, has served its purpose in establishing a basis for the dimensional specification, hence ensuring the interchangeability, of conveyor idlers. The standard is currently under review by a committee comprising users, manufacturers and the South African Bureau of Standards.

Conveyor roller idler is an important part of the belt conveyor, with many kinds and large quantity. It takes up 35% of the total cost of a belt conveyor and bears more than 70% resistance, so the quality of the roller is particularly important. The role of the roller is to support the conveyor belt and the weight of the material. The operation of the roller must be flexible and reliable.
