Improving knowledge of grinding technology and mill operations to operate, optimise and troubleshoot ball mill and vertical roller mill grinding installations. Ball mills and vertical roller mills are used for many grinding applications in cement production raw meal grinding, coal and pet coke, and finish cement grinding.
Vertical Roller Mills VRM. Roller press with Ball mill. Ball Mill. 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 7080 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Optimization of Cement Grinding Operation in Ball Mills. Contact Us . Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses typically in combination with a ball mill, and clinker pregrinders with ball mills.
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.

Optimize your grinding process via temperature control Water injection is one way to control and maintain the cement temperature at mill outlet at a preset level. Depending on the circuit thermal balance analysis and the mill design, Magotteaux water injection system WIS automatically sprays water into the mills in 3 different ways 1st chamber via its inlet 2nd chamber via mill outlet or
The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills. Our ATOX coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent.

The ball mill is traditionally the basic system used for the grinding of raw material, clinker and additives in a cement plant, as well as a wide range of minerals. Benefiting from a large experience, the FCB BMill has been designed to be particularly well adapted for the grinding of products at high fineness and grinding of very abrasive
The ball mill is traditionally the basic technology in a cement plant and is a very reliable machine. It is particularly well adapted to the grinding of products at high fineness, very abrasive products and solid fuels, as well as to a wide range of minerals.
The ball mill is key equipment in grinding industry. It is widely used for the cement, coal, sand, fertilizer, glass, ceramics etc. But its final product cost is high as Ball Mill BM grinding is lowest 5 when compared with Vertical Roller Mil
