The LAARMANN® ball / rod mill is designed to meet the industrial requirements to grind coal, cement and a wide variety of ores. It is related to the Bond ball mill and Bond rod mill work index. This index is used to calculate the power draw requirements of a rod mill and allows for a more precise calculation of the required comminution energy. The RWI index is used for a secondary crusher product size in the range of 25mm down to 2.1mm. The 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. It is complete with an outlet funnel, a set of separation screens, and a sample collector.
Method of operation:
The mill incorporates a yoke and locking mechanism for easy access to the contents. An appropriate ball or rod charge is provided with the mill. The motor has a solid-state controller to accurately control the drum speed. This controller has internal overload protection and can be used to set different drum speeds. The mill can be adjusted to rotate at variable speed. The lid has a quick release locking mechanism.

The Bond Crushing Work Index (CWi) describes the competency of the ore at larger particle sizes. It is used for the calculation of the actual crusher power requirements. The test is conducted using a Bond impact tester, which consists of two pendulum-mounted hammers.
