Cement Grinding Process Explanations

 · Grinding systems are either ''open circuit'' or ''closed circuit.'' In an open circuit program, the feed rate of incoming clinker is adjusted to accomplish the desired fineness of the item. In a closed circuit program, coarse particles are separated from the finer product and returned for further grinding.
