Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of the incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
Therefore, Clinker Grinding Unit system has simple technology, low failure rate, high operation efficiency, compact allocation, construction area of 70% of ball mill, construction space of 5060% of ball mill, and it can help enterprises to save land resources effectively. 3. With excellent environmental benefit, low noise, and low dust.
Some of the admixtures allow fineness to be increased in open circuit mills, whereas in closed circuit mills, considerable production increase can be achieved at the same fineness. The difference is due to the fact that in the latter, the fineness of the product is established by the parameters of the airseparator.
