Aug 10, 2019· Mining Conveyor Belt Comparison Posted on August 10, 2019 by admin . Multiply? Straight warp? Steel cord? Something else? There''s more than just these categories of mining conveyor belt types that you need to consider when comparing equipment for your applications.
The standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.
