Roller press is well-accepted technology in India
In the case of Slag grinding, the acceptance of roller press in finish grinding is well recognised. It offers the distinct advantage of saving of about 6-7 Kwh/t as compared to Vertical Roller Mill at 4200 Blaine. KHD has sold 27 Sag Grinding Circuits and maintains about 70 % market share in slag grinding in India.® can be operated in this case as a finish grinding plant. High-pressure grinding of binding agents is suitable for compared to a roller mill, up to 20 percent of the energy required for grinding can be saved; com-pared to a conventional ball mill, and combi-grinding mode (with ball mill) 500 400 450 350 300 250 200 150 100 50Industrial Solutions polycom high-pressure grinding roll

Crushers Selection Guide: Types, Features, Applications GlobalSpec
There are several types of industrial crushers available to industrial buyers. These types include: Cone or gyratory crushers insert feed via a cone-shape bowl and crush it with a spinning or gyrating head. HPGR (high pressure grinding rollers), roll/roller crushers, or mineral sizers use two large rollers or a roller and a flat surface.pressure and other operating parameters. The most important of the wearing parts are rolls. The wear. rate on the roll surfaces is approximately 1 2 gr / ton.Clinker. This wear rate is not very high.

Clinker grinding technology in cement manufacturing
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits 4 DRIVE YSTEM OR HIGH PRESSURE GRINDING ROLL ROLLXTEND™ 1.

Effect of High Pressure Grinding Rolls (HPGR) pre-grinding and
High pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc.) and cement grinding stages. The energy consumption is 2.5–3.5 kW h/t and about 10 kW h/t when recycling of the material is used.A HPGR consumes 30–50% less specific energy as compared to a ball mill which indicates higher the efficiency of the high-pressure grinding and a separating system optimized for the respective application. Combining a polycom ® high-pressure grinding roll and a static-dynamic sepol ® separator in a finish grinding plant for raw material increases energy efficiency significantly.
