The main gear is cut from a special gear steel casting and is made split and reversible. The pinion, usually integral with the pinion shaft, is cut from an alloy steel forging and heat treated prior to cutting the teeth. The pinion shaft is double ended so it is also reversible. All ball Mill gearing is designed in accordance with sound ...

A ball mill operates 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. The rotation of the cylinder is typically between 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation.

A good maintenance program, as well as rebuilds or upgrades when necessary, is essential. 6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition.

Ignoring mechanical losses in this drive train, the power transmission at each stage, defined as torque x speed, is constant. The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of to RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is ...

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.
