Hammer crusher is directly maximum particle size of 600-1800 mm of material crushed to a period of 25 or 25 mm below the crusher Crusher. Hammer crusher is suitable for cement, chemical, electric power, metallurgy and other industrial sectors crushing medium hardness materials, such as limestone, slag, coke, coal and other materials in the debris and crushing operations.
Classification Of Hammer Crusher
Hammer crusher is divided into: single stage hammer crusher, high efficiency hammer crusher, vertical shaft hammer crusher, reversible hammer crusher, ring hammer crusher. The hammer crusher hammer crusher for ring steel ring, ring type crusher is a variant of hammer crusher. It uses high-speed impact and the combined effects of low-rolling to crushed the material, and thus obtain finer products, mainly used for crushing coal power plants, but can also be used for crushing gypsum, salt, chemical raw materials and some of the hard materials.
- By number of the rotor is divided into two kinds of single rotor and double rotor.
- According to the direction of rotation of the rotor, can be divided into two types of irreversible and reversible.
- According to the arrangement of the hammer, is divided into two types of single row and multi row type. The former hammer is mounted on the same rotating flat surface, and the latter is distributed on several rotating flat surface.
The Advantages And Disadvantages Of Hammer Crusher
Advantages of hammer crusher is: crushing ratio (generally 10 to 25, the higher 50), high production capacity, product evenly over flour phenomenon, low unit energy consumption, simple structure, light quality of equipment, operation easy maintenance and so on. Hammer crusher series is suitable for crushing all kinds of medium hardness and brittle materials, such as limestone, coal, salt, white sub, gypsum, alum, brick, tile, coal and so on. The compressive strength of the material to be broken does not exceed 150 MPa. It is mainly used in cement, coal preparation, power generation, building materials and fertilizer and other industries, it can be of different sizes in crushing into uniform particles, in order to facilitate the next step of the processing, mechanical structure, reliable, high efficiency, good applicability.
The disadvantage is that hammer crusher: Hammer and grate of the screen faster wear, maintenance and looking for long equilibration time, when crushed hard material materials, wear faster; crushing sticky material, easy to plug the sieve grate slit, for easy downtime (moisture content of the material should not exceed 10%). Crushing hard objects, the hammer and liner wear and consume more metal material, easy to wear pieces need to be changed frequently point with more maintenance time, crushing sticky material, the grate is easy to plug and lead production capacity decrease.
