The cement production line generally adopts vertical grinding. For the processing of cement, what we need to do is to improve the fineness of the finished product.
In the main milling equipment, the vertical roller mill has a very high comprehensive performance, integrating crushing, drying, grinding and grading and conveying. The system is simple and compact, and the floor space is about 50% of the ball mill. The vertical roller mill adopts a closed loop production system, which is not affected by natural factors such as weather and can be arranged in the open air, thus reducing a large amount of investment costs.
Under the environmental protection policy, a feature of cement production is the comprehensive utilization of tailings. At this point, the main advantage of vertical roller mill is reflected in the large-scale treatment of industrial slag, fly ash, slag, coal gangue and other industrial waste. There are four grinding rolls and two hydraulic systems in the vertical roller mill configuration, which is especially good for the fine slag. After the vertical roller mill is reused in urban tailings, it is often used to make new building materials. This is a promising project.
Vertical mills are more adaptable to changes in raw material quality and moisture. Closed-circuit grinding and automatic drying recommended by manufacturers can greatly improve the quality of cement aggregates. At the same time, the vertical grinding repair work is simple and easy, and it is much easier than the maintenance process of the general vertical roller mill.
