The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
Step 5: Measure and Check Whether the Shaft and Housing Bore Fit the Bearing. You should check whether the dimensional tolerance fits with the bearing size. You can again use your micrometer or slide caliper. An eightpoint measuring method is recommended for both the shaft and housing.

Each bearing design has distinctly different ball sizes, number of balls, and raceway curvatures that determine the capacity, speed limit, and bearing stiffness. Typically, the bearing design is selected according to the intended type of cutting—roughing, finishing or multipurpose cutting (see Figure 2.) This is only a starting point ...

A ball mill is a crucial piece of machinery used in grinding and mixing materials in various industries. It works by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. Ball mills are used extensively in the mining, construction, chemical, and pharmaceutical ...

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

Ball bearings are rolling element bearings that use balls to separate the bearing races and provide smooth, low friction motion in rotary applications. Ball bearings are manufactured in hundreds of sizes, from the ultrasmall mm diameter bearing for use with miniaturized medical devices and micromotors, to bearings over 15 feet in diameter for use in heavy equipment.
