The circulating load ratio is an excellent subject for study of classification system performance because it has long been recognized as such an important factor in ball milling efficiency. Results from the classical work of Davis (1925) are shown in Figure 2. Note that an increase in circulating load ratio from 150 to 500 percent yielded an ...

Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.

Roughing mills are also sometimes known as ripping cutters. • Greater reduction in diameter occurs in this mill hence the stresses and forces on the transmission shaft are the highest here. Intermediate Mills: • There are six shafts used to transmit power to the intermediate rolling mills. The shafts are numbered from 9 to 14.

Most shafts will transmit torque through a portion of the shaft. Typically the torque comes into the shaft at one gear and leaves the shaft at another gear. A free body diagram of the shaft will allow the torque at any section to be determined. The torque is often relatively constant at steady state operation. The shear stress due to the torsion
