The LAARMANN® ball / rod mill is designed to meet the industrial requirements to grind coal, cement and a wide variety of ores related to the Bond ball mill and Bond rod mill work index
Thi index is used to calculate the power draw requirements of a rod mill. Furthermore it allows more precise calculation of the required comminution energy. The RWI index is used for a secondary crusher product size in the range 25mm down to 2,1mm and BWI index is used from 2,1mm down to 100μm which is the usual product size. The ball / rod mill consists of a gear motor mounted on a high precision solid steel underframe complete with outlet funnel and a set of separation screens plus sample collector.
The mill incorporates a yoke and locking mechanism to facilitate easy access to the contents of the mill. An appropriate ball or rod charge is provided with the mill. The motor incorporates a solid-state controller to accurately control the drum speed. This controller has an internal overload protection and can be used to set different drum speeds. The mill can be adjusted to rotate at variable speed. The lid incorporates a quick release locking mechanism.
