China's manufacturers of cone crushers mainly include Heavy, One Heavy, Shenye, Shangjian, Nanzhong, Huayang Machinery and Shanghai Doring Watson Machinery Equipment Co., Ltd. (hereinafter referred to as Shanghai Doring), followed by Hengye, No. Second Heavy Machinery Plant (hereinafter referred to as "double"), Shen Mine, Zhongzhong and Dahua Heavy Machinery. At the same time, advanced cone crushers produced in countries such as Sandvik and Russia were selected.
At present, China mainly produces spring-type cone crushers and single-cylinder hydraulic cone crushers (each with more than 10 specifications), followed by multi-cylinder hydraulic cone crushers, product varieties, main performance and technical and economic indicators and the former Soviet Union and Eastern European countries. The level of the machine is similar, the life of the whole machine and the main zero, the life of the components (except the liner) are close to the life of similar foreign products. Compared with foreign advanced products, the main gap is centralized control, the degree of automation is slightly poor, the service life of the lining plate is short, and the shape of the crushing cavity should be improved. In recent years, due to the introduction of advanced technology and cooperation with foreign countries, the technical level of the cone crusher is approaching the advanced level of foreign countries.
Heavy in 1986, the design and manufacturing technology of the Symons cone crusher was introduced from Nordberg. This is also a spring-loaded cone crusher, which adopts hydraulic control device such as hydraulic discharge opening and hydraulic clearing chamber. Compared with similar products designed and manufactured by China, the production capacity, particle size uniformity and fine crushed product are fine. Advantages in terms of degree, component life, operation rate, and production and maintenance management costs. At present, this crusher is the main cone crusher of the plant, of which there are more than 20 specifications for standard and short head types.
Cone crusher is metallurgy, building materials, chemicals, utilities, and other industrial sectors for the various road ore or rock of different hardness were broken and the main equipment crushing operations, particularly commonly used as secondary and tertiary crushing plant in beneficiation equipment.
Model Specification PYT(Y,S)-B(Z,D)T(D,C) ××××:P——Crusher, Y——Conical, T(Y,S)——Spring Type ( Hydraulic, Simmons), B (Z, D) - Standard (medium, short), T (D, C) - single cylinder (multi-cylinder, super heavy), × × - cone bottom Diameter (dm), × × - feed port size (cm).
The above-mentioned model specifications are mainly used in heavy weight. At present, the domestic factories have not been completely unified. The ones and other factories have their own slightly different representations. Generally, they are simpler, the letters have the same meaning, and the numbers expressed by numbers are mostly broken. Cone bottom diameter (mm). A standard spring cone crusher with a cone bottom diameter of 1200 mm is indicated as PYB1200.
The following describes the cone crushers produced by major domestic and foreign manufacturers.
1. Heavy Six Factory The factory has a history of manufacturing cone crushers for more than 50 years. It is the leading plant for the production of such equipment in China. By 1991, it had provided more than 1500 cone crushers for domestic and foreign users. The plant mainly produces spring, single and multi-cylinder hydraulic and Simmons types of four types of cone crushers. Among them, Simmons cone crusher has 6 specifications, each of which has two types: standard type and short type. Each type has four crushing chambers of fine, medium, coarse and extra-thick, which can be more It is well adapted to the needs of different users and different crushing processes in medium and fine crushing operations.

5. Shangjian The company currently produces three types of cone crushers, namely PY cone crusher, Φ350 Simmons cone crusher and AF type laminated cone crusher. The latter type of crusher is a new type of cone crusher which is produced by the Kobelco Group (hereinafter referred to as Kobelco) and adopts the laminating crushing technology. It can obtain fine and uniform crushed products and belongs to the new generation of fine crushing equipment.
(1) PY type cone crusher. This series of crushers is suitable for crushing various ores and rocks of medium and above hardness. The utility model has the advantages of reliable structure, high production efficiency, convenient adjustment and economical use. Its spring safety system is the overload protection device, foreign objects can block iron by crushing chamber without damage to the machine, using two kinds of oil or water seal dry form, so that the lubricating oil and powder isolated to ensure reliable operation. The crushing cavity type is determined by the use of ore, the standard type is suitable for medium crushing; the medium type is suitable for fine crushing; the short head type is suitable for fine crushing. Its main technical parameters list 18.
