Advantages of Roller Mills. 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 – 3 0 C) unlike hammer mill that generates up to 10 0 C. 3. Less moisture loss. 4. Better work environment due to low machine noises level.

Vertical Roller Mill VS Roller Press in Cement Industry

With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press. The two types of equipment are different in grinding mechanism, structure design, and product performance, but each has its own advantages. 1.

The two counter-rotating rollers of the roller press exert very high pressure on the material, effectively crushing and weakening the particles. Microcracks are created and make it easier to grind the particles finely. Used as a pre-grinding system in ball mill circuits, for example, production increases of up to 40 % and more can be achieved.

Cement Grinding

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 speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Grinding Technologies

The higher the demands placed on the quality of ground material, and the lower the desired energy consumption of the overall grinding system, the more important is the efficiency of the separator. The sepol® high efficiency separator plays a key role in grinding systems equipped with tube mills, roller mills and high pressure grinding rolls.
