The drive of the ball mill consists of an induction electric motor, twostage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell, see Figure 1, taken from [1]. Figure 1.
Usually, the power of the ball mill pinion shaft was directly proportional to the motor power of the ball mill, and the correlation coefficient was The correlation coefficient and equality (18) [32] were adopted to ensure the safe and stable production of the ball mill, where N e was the motor power of the ball mill. (18) N e ...

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...

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.
Grinding and processing. WEG offers the most reliable and efficient solutions for milling plants for ferrous and nonferrous products with their experience of mill drive systems. In the heart of a processing plant, the ball and SAG mills must be driven by solutions that adapt to the characteristics of the minerals in line with the whole process.
All burrs should be carefully removed by filing or honing. Unless otherwise arranged for, the mill has been completely assembled in our shop. Before dismantling, the closely fitted parts were match marked, and it will greatly facilitate field assembly to adhere to these match marks.
Monzonite Bond Ball mill work indices (Wi) averaged /t, with a maximum variation of ±9%. The inferred average orebody Wi, based on ... Maximum SAG mill power was determined by deducting the installed ball mill pinion power of /t (16,400kW) from the maximum overall circuit power of /t to give /t (18,060kW).

Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing. Small and batch grinding mills, with a diameter of 700 mm and more, are available. These mills are of a special design and described on special request by all Ball Mill Manufacturers.
Gear cutting of a split girth gear for a cement mill having an input power of 2200 HP 5. Separate mill A: Damage to mill cylinder, neck or stub endanger girth gear and pinion. Repairs entail extra work for girth gear dismantling. B : Damage to mill cylinder cannot endanger gear teeth. Mill repairs do not entail gear dismantling. KAANU FAC TU RE 6.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
for size reduction • The energy dE required to effect a small change dL in the size of unit mass of material is a simple power function of the size. • Rittinger's law: putting p = −2, then integration gives: Writing C = KRfc, where fc is the crushing strength of the material, then Rittinger's law, first postulated in 1867, is obtained as: Since the surface of ...
