Cement grinding Vertical roller mills versus ball mills. applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative
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.
Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.
a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
the grinding process remains a challenging issue, due to the elevated degree of uncertainties, process non-linearity and frequent change of the set points and the respective model parameters during operation. For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials.
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. Closed circuit ball mill with two compartments for coarse and fine grinding ...
Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

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.
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
