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.
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 .
CM1 is a ball mill in closed circuit with a high efficiency classifier and a pregrinding system. CM2 is an open circuit ball mill system. The product from CM1 and CM2 are 4700 and 4100 Blaine respectively. To satisfy the strength requirements of the cement, the cement mill feeds for CM1 and CM2 included 68% and 79% clinker, respectively. The ...
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.
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 to the ball mill system and has increased its share of the market for cement mills over

A typical general purpose Portland cement of fineness (specific surface) 340 m².kg-1 ground on an efficient closed-circuit ball mill system requires around 32 kWh per tonne, so a 10 MW mill would produce 313 tonnes of this per hour. In addition to the energy consumption of the mill, the "ancillary" equipment (separator, fans, conveyors, pumps ...
Alibaba offers 176 closed circuit ball mill products. About 52% of these are mine mill, 1% are grinding equipment. A wide variety of closed circuit ball mill options are available to you, such as ac motor, dc motor, and stepper motor.
Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
Reductions in the range of 4-6 kwh/t cement are reported from India, depending upon the product type. In China, for 5000t/d cement production line using a ball mill with closed circuit system, power consumption index is reported to range between 38 ~ 42kWh/t (NDRC, 2008. p.48).
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.
