pyrophyllite vertical roller mill production line

Pyrophyllite is a kind of clay mineral, which belongs to layered hydrous aluminosilicate mineral with crystal structure of 2:1 type. Pyrophyllite is fine in texture and low in hardness (1-2). It is suitable for making blanks (molds) for synthetic diamonds, ceramics, refractory materials, glass fibers, and carving stones. It can be widely used in ceramics, metallurgy, building materials, chemical industry, light industry and other industrial sectors. The production of pyrophyllite is inseparable from the help of grinding equipment. As a pyrophyllite mill manufacturer, the HLM1700 pyrophyllite vertical roller mill production line produced by Guilin Hongcheng has been successfully applied in the market.

More than 90% of pyrophyllite production is consumed in domestic ceramics, refractory materials and glass fiber industries. Japan imports about 20,000 tons of pyrophyllite from China every year for glass fiber. All kinds of pyrophyllite powders are white, and the whiteness is generally above 80%, and the highest can reach 93%. As the powder fineness increases, the whiteness value increases, and the whiteness of calcined wax stone increases, up to 96%. Generally, pyrophyllite is soft, delicate, and not hard. It has good machining performance and is easy to be ground. However, due to the use of Raymond mills to grind pyrophyllite before, the output per hour is low, the efficiency is low, the energy consumption is high, and the product particle size is difficult to control, which restricts the development of this industry. Energy consumption provides equipment assistance.

Recently, an enterprise purchased a set of Guilin Hongcheng HLM1700 pyrophyllite vertical roller mill production line for processing pyrophyllite powder. The fineness of grinding pyrophyllite is: 45μm (99% passed), and the energy consumption per unit product is obviously lower than that of Raymond mill. In order to make the new equipment meet customer requirements, we first studied the physical properties of pyrophyllite, learned that it is a layered silicate mineral, often in the form of scales, leaves or dense massive aggregates, and tested its bond function Index, which provides material property values for equipment design. The leading idea of the new mill design is: on the premise of meeting the user's requirements for the mill, try to use the modular units of the original mill that have been proved to be reliable for grinding other products, and determine the specifications of the new equipment through similar principles . Borrowing the components tested in production can not only reduce the manufacturing cost of the factory, shorten the design cycle, and improve the reliability of the new mill; it can also minimize the psychological burden and ideological pressure caused by the customer's selection of new equipment. The design of the pyrophyllite vertical roller mill production line is based on the ordinary vertical roller mill. Although it belongs to the material bed grinding principle, the difference in characteristics of different materials has a great impact on the operation effect. For the grinding of leaf wax For stone, how to stabilize the material bed, reduce vibration and improve grinding efficiency is the core content of the equipment design. Around these key issues, select reasonable technical parameters and structures for the content of the modified design in the previous section.

The operation effect of the pyrophyllite vertical roller mill production line: the trial operation of the HLM pyrophyllite vertical roller mill production line has gone through three stages: the overall performance debugging of the equipment body, the adjustment of peripheral supporting equipment and the exploration of system parameters, and the equipment problems such as the height adjustment of the retaining ring have been solved, and the exploration and control are good. In terms of raw material particle size, air pressure difference, water spray, feeding amount and slag discharge, the system runs smoothly and normally, the output is stable, and the average power consumption of the system is low, which has been highly recognized by customers. If you also have a pyrophyllite grinding project and need to purchase a pyrophyllite vertical roller mill production line, welcome to choose Guilin Hongcheng as your partner.
