Coal Ball Mill | Grinding for Different Kinds of ...
A high-quality coal mill can effectively solve the fineness problem of coal powder and ensure uniform grinding of raw coal. The fineness of pulverized coal has a great influence on the ignition temperature and burning time of the equipment. In this way, the influence of bad raw coal on combustion efficiency can be well improved by coal mill.
