Closed Circuit Grinding VS Open Circuit Grinding
Although closed circuit grinding offers many choices for arrangement of the equipment as well as combinations of equipment, some of the more common circuits are rod mill/classifier, Ball mill/Classifier, Rod mill/Ball mill/Classifier and Rod mill/Classifier/Ball mill/Classifier.
Circulating Load Calculation Formula
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones.

Grinding Circuit an overview ScienceDirect Topics
The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bidirectional rotational capacity. (Reversing direction evens out wear on liners with symmetrical profile and prolongs operating time.) The

Effect of circulating load and classification efficiency
It was concluded that Equation 2 represents a useful mathematical model for the relative capacity of closed grinding circuits as a function of circulating load and classification efficiency. The model confirms that closed milling circuit capacity increases as circulating load increases and decreases as classification efficiency decreases. The ì model was used to compare fine screens and

Cement mill Wikipedia
Closedcircuit systems The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

The cement mill
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of 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.
