Cement clinker is sometimes ground employing a ball mill. this is often basically an outsized rotating drum containing grinding media – normally steel balls. because the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once each number of seconds.
The drum is mostly divided into 2 or 3 chambers, with completely different size grinding media. because the clinker particles are ground down, smaller media are a lot of economical at reducing the particle size still additional.
Grinding systems are either ‘open circuit’ or ‘closed circuit.’ In an open circuit system, the feed rate of incoming clinker is adjusted to realize the specified fineness of the merchandise. in a very closed circuit system, coarse particles are separated from the finer product and came back for additional grinding.
Gypsum is interground with the clinker so as to regulate the setting properties of the cement. Clinker grinding uses lots of energy and also the cement becomes hot - this will lead to the gypsum changing into dehydrated, with doubt less undesirable results – see the link at the lowest of this page for a lot of data.
Cement Ball Mill
Classic cement mill additionally named since cement ball mill, natural material mill, material grinding mill still as clinker mill, is that the key equipment for milling following the cement crush method, that is widely utilized in the manufacture industries, like cement, silicate, new constructing materials, refractory materials, fertilizer, ferrous metal, nonferrous steelstill as a glass ceramics, etc. Cement ball mill could also be used for the dry still as wet grinding for those types of oresbeside alternative grind-able materials. consistent with completely different materials and discharging strategies, there are dry cement ball mills and wet cement ball mills with regard to alternative.
Cement grinding equipment
In two-compartment cement mills, the first, coarse grinding compartment is supplied with a step lining that’s appropriate for big grinding media and ensures optimum lifting of the mill charge. The shell lining within the second compartment or in a very one-compartment cement mill may be a corrugated lining designed to get most power absorption and grinding potency. For special applications a classifying shell lining could also be equipped for fine grinding within the mill. The ball charge mill consists of grinding media in numerous sizes to make sure optimum grinding potency and simple maintenance. the dimensions distribution of the grinding media within the coarse grinding compartment is meant to merely crush the coarsest particles within the mill feed material and to make sure adequate fineness of the fabric passing the diaphragm. For fine grinding, the charge consists of little balls, that ensures the most effective potential grinding potency while not obstructing the fabric flow through the ball charge.
