a ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. it works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
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 b-mill has been designed to be particularly well adapted for the grinding of products at high fineness and grinding of very abrasive products and solid fuels.

it gives also a rough interpretation of the ball charge efficiency: - ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs): - modification of the ball charge: this calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:
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.
the ball mill for clinker is an efficient tool for fine powder grinding. it is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores. cement ball mill is not only suitable for over-flow grinding, but also applicable for
as for tubular ball mills, vertical mills benefit significantly from the employment of specific grinding additives, both in terms of production increase and cement quality improvement. the effect of grinding additives is evident in all cases, especially in case of high-blaine cem i and blended

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 the ball mill in the cement
a concrete mixer is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. a typical concrete mixer uses a revolving drum to mix the components. for smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens.
