Conventional rotary mills

The hammer mill is a variant of the conventional rotary breaker uses a closed far end with a series of hammers in a hammer mill rotating at this end, which breaks the harder coal and rock so that it is less than hole size and leaves through the holes. 

The equipment used in the industrial production is quite conventional, including stirred precipitation tanks, filters, extruders, concrete mills, spray, belt and rotary dryers, rotary Idlns, and so on. The modernization of the industrial plants has been driven by the need to increase the production capacities (debottlenecking) and to commercialize new generations of catalysts as well as by health, safety, and environmental issues.
