The throughput of a belt conveyor system is the primary design parameter when considering a new installation, determined by the cross-section of the material on the belt, coupled with the belt speed.
Lump Size – The lump size influences the belt specifications and the choice of carrying idlers. There is an empirical relationship between lump size and belt width. For a 20° surcharge angle with 10% lumps and 90% fines, the recommended maximum lump size is one third of the belt width (BW/3). If it is all lumps, then the
What is lump size in belt conveyor? The size of a screw conveyor not only depends on the capacity required, but also on the size and proportion of lumps in the material to be handled. The size of a lump is the maximum dimension it has. A closer definition of the lump size would be the diameter of a ring through which the lump …
