Grinding systems are either 'open circuit' or 'closed circuit'. In an open circuit system, the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system, coarse particles are separated from the finer product and returned for a further grinding.
