V-BELT Ball Mill DRIVE. V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less. Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field assembly. V-belt drives …

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

The ball mill diagram shows the main parts of a ball mill, including the feeding device, the cylinder, the discharge device, the hollow trunnion, the transmission device, the gear cover, the girth gear, the pinion, and the motor. The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use.

Available cylinder sizes range from laboratory mills to 12′ in diameter.. Discharge Features. For discharge of the product on wet grinding processes we offer our standard media retention grate along with an adequate size discharge valve. For discharge of the product on dry grinding processes we offer our dry media retention grate and housing. ...

The ball mills can be operated either in batch or in the continuous mode. In the batch mode, a given amount of material is loaded into the mill and ground for a specific period and then discharged. In a continuous mode, material is fed continuously into one end of the mill and discharged from the other. The feed and discharge mechanisms, which ...
