A Grinding Table for Cement Milling | Engineering360

A milling device sometimes used for grinding cement and industrial minerals is a grinding table. Figure 8 shows a typical example. It consists of a 4 m diameter table rotating around its centre at 20 rpm. On the outside it has a lip around to reduce particle ejection from the table. Four 1.2 m diameter rollers are positioned just above the table.
