Marcy mills are recommended to operate a peripheral speeds governed by the following relationship : Peripheral Speed= D meters/ min. D = mill diameter in meters. The Marcy expression is applicable for mill diameters between to Using peripheral speed, the rotational speed can be determined.
Most discharge via trunnionoverflow; Volumetric loading is similar to that of a ball mill (3035%) Design standards for drive components are more demanding than ball mills; Dry applications feature a peripheral discharge or an airswept arrangement; Typical operating speeds are slower than either SAG or ball mills: 6570% TCS (wet) and 6263% ...
From the smaller installations to the very large cement clinker mills we provide the optimum solution. Open/closed circuit operation for wet or dry milling applications. Rod Mills for coarse grinding, fitted with trunnion, end peripheral or central peripheral discharge. Ball Mills for fine grinding fitted with trunnion or diaphragm discharge.
The newly developed peripheral discharge rod mill has great differences in structure and discharge feeding mode, which is the key to distinguish rod mill from overflow ball following is a comprehensive introduction of the discharging and feeding of the surrounding bar mill.
