Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed ...
Cement – Tube mill internals – Grinding media. Changing impact conditions can cause conventional grinding media to either work harden or cause spalling – thus shortening working life, increasing downtime and increasing costs.

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. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
The grinding medium of cement dry ball mill includes steel ball, steel rod, steel pipe, stone, porcelain ball, etc. the steel ball is divided into cast iron, bearing steel, carbon steel and other materials, and the diameter of steel ball varies from 15mm to 125mm.
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
determine what media size(s) addition will maximize any given plant ball mill's grinding efficiency (Fig. 1). The functional performance parameters "mill grinding rate through the size of interest," and "cumulative mill grinding rates" from both plant and small-scale tests are applied to this task. A plant media sizing methodology, and
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, the …
