Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Coal mill is the main equipment in the pulverized coal preparation process.Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the pulverized coal preparation system is one …

Our OK Mill with its patented roller and table design delivers the best power efficiency of any cement vertical roller mill. It uses five to ten percent less power than other vertical roller mills. In addition to efficiency, the unique design also makes the vertical roller mill more stable in operation than other vertical roller mills, offering ...

Cement ball mill The cement ball mill is a horizontal cylindrical rotating device with outer gear transmission. The rotation of the cylinder produces a separation Heart force brings the steel ball to a certain height and then falls. Cement ball mill is used to grind cement raw materials, it is divided into dry method and wet method.
