Vertical Roller mill is the main equipment in cement grinding. In the process technics, compared with the closed-circuit grinding, opened-circuit grinding process is only more saving invest, and more facilitated in the maintenance and management. However, the adjustment of closed-circuit grinding is much more convenient and more adaptable to the quality changes and moisture of raw materials.
Some experts on recommending opened-circuit vertical roller mill believe that the particle size distributions in the open-circuit cement grinding process are wider. So the opened-circuit grinding is welcomed in concrete mixing station. To choose which one, the cement factory should be based on the actual situation of their choice. But LM series vertical mill apply to both.
In the production of modern cement industry grinding mill system operations, including raw material grinding, cement grinding slag grinding and coal preparation. Is generally believed that the power consumption of the unit cement grinding materials accounted for 60% to 70% of the power consumption, improve efficiency, reduce grinding power consumption has been the focus of the cement industry grinding technology.
Raymond mill in the traditional on such basis as technological innovation, the technical indicators from the mill drive-year tradition of Raymond has greatly improved, Raymond is a new energy-efficient machine. HC Series wollastonite mill for grinding limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphate, bentonite, starch, kaolin, etc. The next seven Mohs hardness, moisture and humidity below 6% within the non-flammable and explosive materials. Fineness of 0.18-0.015 (80-800 mesh) between the arbitrary adjustments.
Ball grinding mill is the huge grinding machinery utilized in grinding plant. It really is capability is very significant, and primarily used in coal, cement clinker, mineral ore and stone grinding mill. Ultrafine grinding technology lately combined with modern high-tech and new materials industry and created a new crush engineering technology, has become the most significant industrial minerals along with other garbage, processing technology, among the modern high-tech industry The introduction of great significance.
