PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL … Land cement grinding. The cement grinding and drying system be dovetail of a large array of obsolete incompetent equipment and was completely replaced by a single VRM, it improves the fineness and diminish the maintenance and power consumption [1, 34, 36].
VRM has been a more compact unit is quite smaller about the ball mills thus significantly reducing civil engineering cost about a ball mill plant. Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues.
meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and finish grinding. This mill-system claims to have advantages of ball mill, roller mill and roller press in terms of reliability and energy savings. The energy saving is claimed to be similar to roller press, around 20 % less ...
The Ball Milling is very popular in grinding industry and the ball mill is the key equipment used. It is widely used for the glass crushing industry, silicate product, ceramics, cement, different building material process, chemical fertilizers, fire-proof material, black and non-ferrous metal etc.
The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over
mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is 30-45 percent lower for cement grinding and 40-50 percent lower for slag. The OK mill can contribute significantly to profitability and. More
In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed.
