Selection of coarse crushing equipment Mine ore beneficiation plant treated metal is generally hard or hard minerals, the choice of suitable jaw crusher or gyratory crusher; In certain non-metallic minerals or cement industry, when a hard or soft mineral processing, also A counter crusher can be used. Jaw crusher has a wide range of applications, and large, medium and small concentrators can be used. The main advantages of the jaw crusher are: simple structure, light weight, low price, easy maintenance and transportation, small height and low plant height; in terms of process, it is reliable, adjusts the discharge port, and is broken and wet. Ore and ore containing more clay are less likely to clog. The main disadvantages are: the lining is easy to wear, the processing volume is lower than that of the gyratory crusher, the product size is not uniform and the oversize is too large, and the uniform feeding is required, and the feeding equipment needs to be set. The gyratory crusher is a high crushing capacity equipment, mainly used in large and medium-sized concentrators. Compared with the jaw crusher, the main advantage is that the processing capacity is large, and the processing capacity is 2.5-3.0 times that of the jaw crusher under the same width of the mine mouth and the discharge port; the power consumption is less; the crushing chamber lining The board wears evenly and the product size is uniform; the gyratory crusher with the specification of 900mm or more can be filled with ore, and no mining equipment is needed. The main disadvantages are: the equipment is more complex in construction, the weight of the equipment is large, the foundation is required to be strong, the body is high, and the factory building is required. The domestic rotary crusher has the common type and the light type. The light type is generally only suitable for the ore with low hardness and low density such as broken limestone ore. In addition, there are two jaw crushers and gyratory crushers suitable for use under special conditions. One is a large-sized detachable hoisting crusher, suitable for crushing operations in underground mines; the other is semi-fixed or mobile crusher, suitable for crushing operations in underground mines; the other is semi-fixed or moving Crusher for rock or ore crushing operations in fixed or irregular moving locations in open pits. For large and medium-sized concentrators, before determining the use of jaw crushers or gyratory crushers, technical and economic comparisons should be made from the aspects of total equipment weight, installation power, capital investment, operating expenses, equipment configuration and process operation advantages and disadvantages. . Specifically: (1) Basic chemical raw materials, including three acids (hydrochloric acid, sulfuric acid, nitric acid), two alkalis (soda ash, Caustic Soda) and various inorganic salts. They are important raw materials in various industrial sectors. In addition to being widely used in the chemical industry, they are used in all walks of life, including mining, metallurgy, machinery, and light industry.

How to make the right choice for crushing equipment?
The type and specification of the crushing equipment must be adapted to the physical properties of the ore, to meet the processing capacity and product granularity requirements, and to consider factors in equipment configuration. The physical properties related to ore crushing performance are mainly ore hardness, density, viscosity, clay content, moisture and maximum particle size in the ore. The relationship between the maximum grain size of the ore and the width of the crusher feed is one of the main factors in selecting the crusher specifications. Materials Gongyi Hengchang metallurgical plant in the art that, for the coarse crusher to a maximum particle size should not exceed ore ships to the mine mouth width 0.8-0.85; for, the fine crusher is not greater than 0.85-0.9.
