Roller press with Ball mill. Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
The belt conveyor mix clinker, gypsum and admixture in a certain proportion and transport them to the cement mill for further grinding, such as cement roller press, cement ball mill, cement vertical mill or group of them. The cement mill grinds all materials into certain size.
Process Of Roller Press Grinding Ball Mill . We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore ...
The roller press is often used where energyefficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the subsequent fine grinding is .
Besides, when used together with a ball mill, it can be used in various process flows, like pregrinding, mixing, semifinished grinding, finished grinding, and more. Due to the change in its grinding principles, this roller press and its grinding system have more advantages, like 50 lower power consumption, and 100300% higher productivity.
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media.

Current systems for steel slag grinding that include ball mill systems, vertical mill systems and roller press systems on the market.. The ball mill system has high energy consumption, high noise and small singleunit capability, but the ball mill has low investment and it .
Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...
Feb 10, 2016· VRM vs Ball Mill for Cement Grinding. Good Days! Gentlemen, Anybody in this forum who have had some practical/extensive experience on Vertical Roller Mill being used for cement grinding? We are planning to put up a new cement grinding plant using Vertical Roller Mill(300350 – TPH) and before implementing the project, we would like to
