- maximum lump size on belt conveyors

Mar 06, 2021 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 would pass.30
