· 1. Introduction. Breakage of minerals is an energy intensive process. Energy for the comminution of raw coal in power plants consumes nearly –1% of the gross power generation (Shi et al., 2015).This proportion would increase to over 55% in the mineral processing plant (Narayanan, 1987).In this case, selection of alternative grinding devices is mainly based on .
Grinding of coal generally uses two types of crushers, namely, the drum crushers and the hammer crushers. The drum crushers consist of two parallel set of drums stocked on circumferences of the performances in the form of spikes, rotating at high speed in opposite directions. Getting between the rotating drums coal is crushed and falls out of the drums. The .
consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if chemical effects may play important roles. UNESCO – EOLSS SAMPLE CHAPTERS CIVIL ENGINEERING – Vol. II ...

The grinding force for coal pulverization is applied by a loading frame. This frame is connected by vertical tension rods to three hydraulic cylinders secured to the mill foundation. All forces used in the pulverizing process are transmitted to the foundation via the gear reducer and loading elements. The pendulum movement of the roller wheels provides a freedom for wheels to .
