2017-11-27  Carrying idlers (Troughing or flat) Support the belt in the section of the conveyor that transports the material . These idlers may be flat or troughed to shape the belt to prevent spillage and are available in 20°, 35° and 45° trough angles with equal or unequal roll lengths . Normal spacing is 3 to 5 feet . impact idlers (Troughing or flat)

How to confirm the spacing distance between the

2020-2-26  The spacing distance between the upper carrying idlers can be increased to 2.5 to 5.0m, and the spacing distance between the lower return idlers can be increased to 5 to 10m. However, this design must be based on sufficient dynamic analysis to ensure reliable conveyor operation.

2020-3-4  Unequal Troughing (Picking) Idlers are used to reduce the height to aid in magnetic separation, picking, sorting, or manual separation . The inclined roll ends turn up the belt to minimize spillage . Rubber disc rolls are also available . The load ratings are greatly reduced from standard troughing idlers because most of the weight is on the long

Design Considerations for Conveyor Belt Idlers -

2010-8-21  Now, to calculate the spacing between the two idlers we will use the eqn.1.1; S=(8*50000*0.015)/(15+165.34)*9.81 = 3.391 m. The diameter of the idler can be calculated from the eqn.1.3 as below: D= (60*1.68)/ (3.14*50) = 0.64 m. Total load acted on each idler

Therefore, if the average speed is 968 feet per minute, as the speed increases from 800 fpm and slows to 800 fpm, the speed is significantly higher at the outer edges. The actual speed may be 1,000 fpm, or more.

2013-1-22  The spacing of the idlers in the loading zone of the belt is about half the normal spacing of idlers in the carrying side. A set of self aligning idler or training idler should be provided at the carrying side and return side at an interval of 15m on the carrying run and 30m at the return run.

2021-3-26  Idler arrangements are configurable in the 24m–long test facility for inline, offset and belt-friendly types. Belt stresses at the idler junctions of these configurations are measured by applying strain gauges and load cells. The offset distance can be varied to determine the effect this has on the developing idler junction stress.
