This size reduction operation can be divided into two major categories depending on whether the material is a solid or a liquid. If it is solid, the operations are called grinding and cutting, if it is liquid, emulsification or atomization. All depend on the reaction to shearing forces within solids and liquids. GRINDING AND CUTTING

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

A mill ready to start a grinding operation could be around 150 t in dead weight. Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it. Figure 8.11 illustrates a typical change in torque with increasing speed of motor. It can be seen that the peak torque of 140% of the running ...
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
18.9.3 Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.

Description This invention is directed to grinding mills, and in particular to arrangements for controlling the discharge of fine material from mills. In the use of grinding mills for the reduction of friable material the efficiency of mill operation is dependent upon satisfactory extraction of ground material from the mill.
In fact, in the same application a Vertimill has 50% less footprint than a ball mill. Lower operating cost. Vertimill is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency.
