25 tph Cement Ball Mill

A ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls.A cement ball mill is the equipment that is used to grind the hard, nodular clinker from the cement kiln into the fine grey powder. In the production of cement, clinkers are the sintered lumps exiting the cement kiln. Clinkers are typically 1 to 25 mm in diameter. Many customers have inquired Zenith that whether we can offer the 25 tph cement ball mill. To our pride, we have exported a certain number of cement ball mills around the world, and they have made a great contribution to local cement industry. Here we focus on more details of 25 tph cement ball mill.

Cement Ball Mill Design

Cement ball mill is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls grind the clinker. The drum rotates approximately once every couple of seconds. Grinding systems of cement ball mill are either 'open circuit' or 'closed circuit'. In the open circuit system, the feeding rate of clinker is adjusted to achieve the desired fineness of the product. In the closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Generally, closed circuit grinding systems are widely held by cement producers. Of course, the 25 tph cement ball mill adopts the closed circuit grinding system. Engineers from Zenith suggest using the φ2.4×9 cement ball mill whose capacity ranges from 25 tph to 30 tph. And the 25 tph cement ball mill needs 570 kw powder. The feeding size of this project is not more than 25 mm. The reduction ratio can achieve to 5.6, which is higher than other brand of cement ball mill.

Outcome of Project

Many customers think highly of the 25 tph cement ball mill, and we sent specialists to install the processing line and train local working staff. Some clients even write commendatory letters by themselves and sent them to our after-sale departments. Up to now, many project run very stably. We feel it a great honor to participate the development of local economy.
