These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semi autogenous ballmillcrushing circuit, and the application is well described. This refers to highaspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

It is these characteristics in addition to flexibility in the machine's design that have made open gear drives the most common type of drive used for ball mills and grinding mills, kilns, dryers, draglines and shovels. There are two types of open gear drives; Type 1 utilizes a rack whereas Type 2 utilizes a gear or series of gears.

The ball mill reducer and gear feature firm, wearresistant, safe ...
Generally, you should replace all the old lubricating oil and clean the machine thoroughly after the mill was put into work as long as one month. After that you should change the lubricating oil ...
The ratios are roughly: 66/30 = :1 for the higher speed and 72/26 = :1 for the low speed. The only small items that need to be done are a belt guard and a lever to lock the rotation of the shaft. This will mean tightening the main nut onto the belt drive is easier and there will be something to react the forces when tightening the collets.
The ball mill is a cylindrical form of container that is driven by a toothed circular gear by couple of gears present in the gear box. The gear box is a setup intended for making the power transmission from the electric motor to the ball mill. During this stage the gear box plays a crucial role in terms of controlling speed and torque.
Large girth gears are installed around the cylinder to rotate the horizontal ball mill cylinders. A pinion connects these directly to the industrial gear unit. SEWEURODRIVE does not just provide industrial gear units, we provide the complete drive package with specially segmented girth gears. We have developed an extremely flexible concept for ...

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.

For small ball mills, the power draw under dry batch grinding conditions was derived by Austin et al. [5] and the same considerations apply for rod mills. Equation () indicates that like any tubular mill the variation of mill power with speed in a rod mill is almost linear. This is true at the initial stages but breaks down when the critical ...
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
