Mar 09, 2018· Make your mill most efficient with a permanent optimum filled ball mill chamber! Reduce your specific energy consumption and wear of balls and liners. SmartFill is the key for that!
The maximum fineness attainable by open circuit stirred mill tests is 6200 cm 2 /g. • During the open circuit tests, specific energies excessively increases beyond Blaine values of 4500 cm 2 /g which corresponds to a specific energy consumption of 60 kW h/t. Beyond this point, further grinding can be obtained for the speeds above 600 rpm.
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further 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.

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 are generally found in cement plants for cement grinding.
Jan 07, 2015· For Blaine fineness of over 3000 cm2 /g; a closed grinding circuit obtains a lower consumption (kW/t) than the open one. 2.0 Diameter & Length of Mill: The diameter and the length of a tube mill depend on various factors. the most important factors are capacity, hardness of the material, feed size, fineness of the finished product, open or ...
Material passes steadily through the open feed trunnion of the mill. It is then ground to desired fineness and discharged at the opposite end. Closed Circuit Systems Continuous Mills are used in closed circuit operations for maximum control of product size, economical grinding and low contamination.
Ball consumption varies with the fineness of the product, hardness of the ore, quality of ball, and whether a mill is run in closed or open circuit. The ball, consumption for mills delivering a coarse product, all passing 8-mesh- and containing 10 to 20 per cent. below 200-mesh, the mill being run in open circuit, is about ½ lb. per ton for ...
Dec 10, 2019· The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the "new type of high fineness cement ball mill" and "open flow high fineness cement ball mill". There are three cement processing circuits. 1. Open circuit grinding
Ball Mill Application Cement Industry- Aluneth Mining. The application of ball mill in cement industry dates back more than 100 years the ball mill for cement grinding plant is mainly of high fineness dry grinding method and the process is mainly of open circuit process and closed circuit process the equipment of ball.
There are two basic types of ball grinding systems: open circuit and closed circuit. In the open circuit system, the mill product has the fineness required for the next stage of the process. In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next stage, and a thick fraction ...
