Recently, Polaris Energy Conservation Network learned from the Ministry of Science and Technology, Russia's National Research and Technological University, Moscow Institute of Iron and Steel Alloy and Russia's National Atomic Energy Corporation, "leading Chemical Technology Research Institute," a joint-stock company research team to develop waste from fertilizer production - - Phosphogypsum extracted with an important strategic significance of rare earth elements, thereby reducing the import of rare earth.
Rare earths are widely used in the production of high-tech products such as lasers, electronics and computers, and are increasing at an annual rate of 15%. China is the world's largest producer of rare earths.
Russia uses sulfuric acid to process apatite to produce phosphate fertilizer. During this period, it generated about 320 million tons of industrial waste phosphogypsum, which contains about 80-98% of gypsum components widely used in the building materials industry and 800,000 tons of rare earth elements.
This innovative new technology addresses three issues in a single step: extracting important rare earth metals from industrial waste, building material gypsum, and recycling waste. Researchers have started trial production and are planning to produce the first batch of rare earth products in 2016.
The machine also has a self-cooling function, especially active abundant hand processing thermoplastic, fibrous material use and chemical heart medicine, seasoning, paint, pigment, dye, feed, plastic, carbon black, Catalyst, aluminum hydroxide, alumina, talc, mica, graphite, AC foaming agent, petroleum coke, pesticide, dye, coating, flame retardant, carbon black, electronic materials, rubber, metallurgy, ceramics, food, building materials, ore, cement, refractory materials, inorganic minerals, cereals and other ideal equipment for crushing.
Through the high-speed rotation of a special shape of the moving disk, it is squeezed, collided and cut for many times, so as to achieve crushing. The material receives impact and shear between the high-speed rotating rotor and the stator of the toothed lining. The crushed material enters the grading area driven by the air flow. The qualified material is collected by the cyclone and dust collector, and the unqualified material is returned to the crushing area for crushing.
â—1. The machine has compact and reasonable structure, small size, low energy consumption, high efficiency, stable speed, low noise, reliable sealing, no dust pollution, simple installation, easy disassembly and repair, convenient replacement of damaged parts;
â— 2.The equipment adopts the specialty of domestic and foreign dry mechanical crusher, according to the need to use large air volume into the cavity or water jacket cooling, in order to reduce the crushing heat, to prevent the shortcomings of material particles sticking to the wall, sticking to the crushing surface;
â—3. Crushing, grading machine, can reach the fineness of the material timely distribution out, avoid over crushing, material size distribution is narrow;
â— 4.Suitable for processing a variety of materials in various industries, without stopping, can adjust the strength. Product particle size uniform, fineness up to 10-5um3
5 Dry materials with water content less than 10% can be crushed by this machine: special materials with water content up to 15%, such as whole wheat flour;
â— 5.For the aggregate, has a good scatter and dispersion function, with automatic screening is not easy to crush the function.
