With the development of economic strength, compared to twenty-first Century the need for large vertical roller mill such large equipment, such equipment production quality is light, covers an area of small, small production system, investment and production cost of the corresponding low, the same level of large equipment operation.
Vertical roller mill is the key equipment for crushing the material after crushing, and it belongs to a kind of large-scale grinding equipment. Vertical roller mill is usually used to manufacture cement raw material, so it is also called lime mill. Of course, the use of vertical mill is not limited to the grinding of limestone, it can also be used for chemical, ceramic, water slag, steel slag and other materials of milling production. These materials are critical to metallurgy, aerospace, electronics, construction, refractories, machinery, and the formation of a complete organic chain.
Vertical roller mill is mainly composed of powder selecting machine, grinding roller device, grinding disc device, pressurizing device, reducer, motor, shell and other parts. The utility model can be widely used in cement, electric power, metallurgy, chemical industry, nonmetal ore and other industries, and is used for grinding lumps, granules and powdery materials to the required fineness.
1. vertical roller mill runs reliably. Installation of automatic control system, remote control can be achieved, easy to operate, rod sets and disc lining board installed to prevent direct contact devices, to avoid destructive shock and violent vibration;
2. high performance. The material in the vertical roller mill residence time is short, easy to detect and control the product size and chemical composition, reduce repeated grinding, product quality is more stable, by adjusting the temperature of hot air, which can meet the different requirements of the humidity material;
3. vertical roller mill investment cost is low. The roller of the vertical roller mill is directly rolled and ground material on the grinding disc, the energy consumption is lower than that of the ball mill 30%-40%, and the roller and the lining plate are made of high quality material, and the abrasion resistance is stronger.
