Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Why Are the Grinding Steel Balls of Ball Mill Worn Out ...

· When the ball mill machine does the wet grinding, if the steel balls are in contact with the substance with a certain acidity or alkalinity, they will be corroded. Besides, the cutting force of material can damage the passive film of grinding steel balls. Then the corrosion and wear stimulate each other.

SIZE REDUCTION

At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.

Wet mills can also be adjusted to reduce the likelihood of wear to the milling media or grinding chamber. If a product needs to be in a dry powder format, after wet milling it requires an energyintensive drying process. Dry milling techniques, including fluidized jet milling with superheated steam can save this step, possibly also sparing costs.
