With the rapid development of technology, rare earth is an important non-metallic mineral regard as industrial vitamin, cannot be replaced. It has excellent magnetic, optical, electrical properties, therefore, widely used in the metallurgical, military, petrochemical, glass, ceramics, agriculture and new art materials area especially in the development and application of modern functional materials, rare earth elements become an indispensable qualified raw materials.
Applications of rare earth can be divided into traditional and emerging areas:
First, in the field of traditional industries, such as agriculture, rare earth as a plant regulator both for growth and physiology, have three characteristics of improve capacity and quality, resistance, can enhance the crop drought resistance, water logging resistance and lodging resistance; a big amount of 1/3 rare earth been used in the metallurgical industry, added to molten steel to improve the often and low temperature toughness, fracture resistance, reduce heat brittleness of certain steel; also can be used as graphite spheres agents, nucleating agents and control agents of harmful elements; in the application of non-ferrous alloys, non-ferrous metals have good effect based on a variety of alloys; in the petrochemical industry, rare earth used in petroleum cracking industry as zeolite cracking catalyst, it is characterized by high activity and selectivity, high productivity of gasoline; in glass industry, there are three applications: glass colored, glass discoloration and production of special properties of glass; in ceramics industry, rare earth can be added into ceramics and enamel, reduce cracking and make enamel brighter, and more important is used as ceramic raw materials; in electric light industrial areas: rare earth as a fluorescent light-emitting materials, is an energy-saving light source, characterized by good light efficiency, good light color, long life; in the textile industry: rare earth chloride is also widely used in tanning skins, fur dyeing, dyeing wool and carpet dyeing and so on.
Second, the rare earths’ application is very significant in high-tech industries, such as rare earth luminescent materials used in display screen; can be obtained nickel-hydrogen batteries, in instead of other permanent magnet materials, allows the device size and weight decreased exponentially; also used as a solid-state laser materials and inorganic liquid laser materials activator; can produce a variety of special-purpose scissors, automobile engine; at the same time, as raw materials to make high-quality, petroleum cracking catalysts; an important raw material of making high temperature superconducting material, oxidizing atmosphere in high-temperature furnace heating body.
It can be tell that rare earth has good prospects both in the traditional industrial areas and in high-tech applications field, mill equipment can grind rare earth into finished products with different fineness. With the technological advances of modern milling progress, a new generation of Raymond mill, ultrafine mill, vertical mill and other equipment has a very high value in the field of rare earth deep processing, both in the production process improvements of high-tech ceramic or have ultra-high milling technology is highly required on the ultra-fine powder, has provided a broad space for the application and development of rare earth.
For physical and chemical properties of rare earths, Hong Cheng ultra-fine milling machine provides a complete production line for the milling and processing of rare earth. HCH ultra-fine mill is an excellent representative of the field, make rolling, milling, and other comprehensive impact mechanical crushing performance into one system. Material is processed into finished products fineness of 400-2500 mesh which can be freely adjusted based on customer’s demand, fineness uniform particles, high-quality can bring a strong market competitiveness, is a truly efficient, energy saving, environmental protection, especially for non-metallic minerals’ deep processing
