lump size maximimum for 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 aMaximum Lump Size for Pipe Conveyor Transport – bulkonline Dear All, For transporting 150 mm lump size iron ore , I selected 600mm pipe dia with 32 m/secmaximum lump size on belt conveyors Mining150mm lump size for pipe conveyor Dear All, For transporting 150 mm lump size iron ore , I selected 600mm pipe dia with 32 m/sec belt speed But some body expressed his doubt As per him, for a lump size of 150mm pipe conveyor is not suitable Kindly, help RegardsMaximum Lump Size for Pipe Conveyor Transport
