Classification of rare earths 1) Light rare earth (also known as 铈 group): 镧 , 铈, 镨 , é’• , é’·, é’ , é“• , é’† . 2) Heavy rare earth (also known as é’‡ group): 铽 , é• , é’¬ , é“’ , é“¥ , 镱 , é•¥ , é’ª , é’‡. The difference between the 铈 group and the é’‡ group is because the rare earth mixture obtained by separation of minerals is often named after the ratio of lanthanum or cerium. Rare earth metals (rare earth metals), also known as a rare earth element, is a general term for a group â…¢B periodic table scandium, yttrium, lanthanides 17 elements, commonly represented by R or RE. Their names and chemical symbols are é’ª (Sc), é’‡ (Y), 镧 (La), 铈 (Ce), 镨 (Pr), é’• (Nd), é’· (Pm), é’ (Sm), é“• (Eu ), Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. Their atomic numbers are 21 (Sc), 39 (Y), 57 (La) to 71 (Lu). The element “Ce†“铈†was discovered and named by the German Claupros, Swede Usbizzi, and Singel in 1803 to commemorate the asteroid, Ceres, discovered in 1801. The rubber crushing machine consists of one crushing machine, cyclone separator, electric control cabinet and water supply mechanism. The Rubber Crusher is mainly used for processing rubber powder from waste tires.

The application of rubber powder can be divided into two major areas: one is the direct molding or with new rubber products, which belongs to the category of rubber industry; Second, it is applied in the wide field of non-rubber industry. At present, more and more manufacturers around the world use rubber powder instead of raw materials, which is not only beneficial to environmental protection, but also more important because the use of rubber powder can effectively reduce the cost, improve the performance, can get the effect that other materials can not. It can be widely used as rubber, filler and composite material for tires, rubber pipes, rubber tapes, rubber shoes, rubber industrial products, wires, cables and building materials. Rubber powder can also be used with plastics, such as polyethylene, polypropylene, polyurethane, etc., to improve performance and reduce cost.
