Cement grinding operation may be performed in one of the following mill setups. Ball and tube mills. Vertical Roller Mills (VRM). Roller press with Ball mill. Ball Mill. Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical ...
The roller press ROP is designed to grind raw meal or for pre-grinding in two-step grinding processes in combination with a ball or a vertical mill.
Roller presses developed for grinding a range of raw materials, are often used in the cement industry for grinding limestone (raw meal), cement clinker and blast furnace slag. The roller press can work together with a ball mill for pre-grinding or be used alone for the finish-grinding of the material. This roller press system is now used by ...

Cement is ground in roller press only. Rule of Thumb. 1 [kW] absorbed in the press replaces 2 – 2,5 [kW] in the tube mill. If roller press is used as a retrofit for existing systems, capacity increase of. 25 – 50 [%] can be achieved. 3.2.1.1 Hybrid / Pregrinding System. Main Elements (Figure 9)
2. Design Structure. There are essential differences between the design structures of vertical mill and roller press. In a vertical roller mill, the material on the grinding disc is restricted by the air duct ring, but the side of the material …
Stability in operation: Feeding material like fly ash, GGBS are fine in nature and they show a fineness below 3 mm hence where other grinding systems like vertical roller mills required water spray to form a grinding bed but in roller press when a pre-mixing of fines with coarse material is made properly it can efficiently grind up to higher ...
The most noticeable feature of the roller press cement pre-grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required. The finished product cement from this system has all been ...
Fig. 3 Roller press . Fig.4 clinker crusher. Since the Hydraulic roller press for clinker grinding is used widely in our country, we focus mainly on the development and cost reduction exercise on this machine. This is done to sell this machine in this competitive world in a competitive price. METHODOLOGY . I. Collect data of the existing roller ...
The roller press is used for crushing minerals like clinker, limestone, slag, and trass in the cement industry. It crushes minerals between two counter-rotating cylinders under high pressure, forming a thin band or "cake" of crushed material. This crushing reduces energy consumption in grinding mills and extends the life of mill components. The roller press …
There are basically 4 types of cement mills in use today: Ball Mill (BM) Ball Mill (BM): predominant despite higher energy consumption partly because of historical reason but partly also because it still offers considerable advantages over other mills, often operate with roller press for pregrinding or in combined grinding;

Roller presses grind raw materials and cement in a cost-efficient way. However, the highly dynamic process causes excessive stress on the bearings of the grinding rolls and the two drive trains, which ultimately fail and lead to unplanned stoppages. An online condition monitoring system that uses acceleration sensors can help avoid such stoppages.
