Coal preparation plant

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).

Experimental Study of an Orientation and Resin-Lifting ...

 · During roof bolting in underground coal mines, the effect of gravity on the resin for anchoring the bolts, resin mixing methods, and borehole wall collapse can easily lead to resin outflow, nonuniformity of the resin, and poor bolt concentricity. In this study we developed an orientation and lifting device (OLD) for resin-anchored rock bolts.
