a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.
Planetary ball mills are frequently used for the development of new materials by mechanical alloying due to their high energy input. The processes and reactions which take place in the grinding jar during grinding can be monitored and recorded. The PM GrindControl is available for stainless steel grinding jars of 250 ml and 500 ml.

Steel and aluminum mills know that monitoring the roll grinding process for quality control improves the performance of work rolls and back-up rolls (BURs) used throughout the mill. Work rolls touch all product surfaces that pass through a mill. Therefore, any pattern or lead line on these rolls is imparted onto the strip surface.
holds the grinding media inside the grinding zone. This enables the highest throughput rates without the build-up of pressure in the grinding chamber and creates the ideal conditions for circula-tion or multi-pass operation. For precise temperature control, the agitator mill is equipped with a multiple-zone cooling system. In the standard
AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′.
