According to the physical and mechanical properties of minerals, the shape of the nugget and the required product size, crushing force, and the crushing force of broken machinery.

The hammer crusher also named hammer mill. Hammer Crusher is mainly used for crushing medium-hard or brittle materials with hardness not more than 300Mpa and 15% moisture such as barite, limestone, terrazzo, silica sand stone, coal, coke, gypsum, aluminum sulfate, slag, salt, chalk, blocks, cement, alumen, brick, tile, etc. It has the features of simple structure, big crushing ratio, high production efficiency, uniform particle size, etc.

1. Purpose: metallurgy, mining, chemicals, cement and other industrial sectors, each year a large number of raw materials and reuse of waste crusher processing, such as in the concentrator for the useful minerals in the ore to achieve single separated, you need to use the crusher ore to the grinding process the required particle size. Mill and then broken to provide the raw mill to a particle size of monomer separation of useful minerals. Another example is in the cement plants should raw material crushing, so that firing the clinker, and then in the clinker mill ground into cement. In addition, in the construction and road-building industry, with broken machinery, raw material crushing to the operational requirements of next granularity. In the coking plant, sinter plants, ceramic plants, glass industry, powder metallurgy and other sectors to be broken machinery raw material crushing to the operational requirements of next granularity.

2. Significance: in the chemical industry, power sector, the crusher and mill machinery, raw material crushing, grinding, increase the surface area of the material, to create favorable conditions for shortening the time of the material's chemical reaction. With the rapid industrial development and resource decreases rapidly, the various departments to the production of waste re-use is very important, and the reprocessing of these waste handling required crusher to be crushed. Therefore, broken machinery plays an important role in many sectors. stone jaw crusher: http://www.hx-crusher.com/crusher.html

The choice of the mechanical performance of the ore and the hammer crusher:

Ore are composed of many minerals, the physical and mechanical properties of various minerals vary widely, so when the crusher force with ore adapted to the nature, will have a good crushing effect. Hard ore, more appropriate to break with the impact to broken, if the grind, the parts will be subjected to severe wear. For brittle ore, splitting and bending broken more favorable, if the grind and powder products will be increased.

Common soft ore: coal, galena, anthracite, and its compressive strength is 2 ~ 4Mpa, the largest not more than 40Mpa. S & P-type hardness coefficient is generally 2 to 4, another example, in the hard ore: granite, pure brown iron ore, marble, etc., the compressive strength is 120 ~ 150Mpa, S & P hardness coefficient is generally 12 to 15, as well as the hard ore, extremely hard ore, the S & P hardness factor of 15 to 20.

As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior vibration sieve, spiral concentrator, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
