Coal Crusher 250 Ton Per Jam
Coal Crusher Introduction:
Coal crusher (referred to as the back-breaking) and hammer crusher belong to impact the role of the main machine to crushing brittle materials, also called coal crusher. The series equipment suitable for the size of not more than 500 mm, the compressive strength of not more than 350MPa of various materials (granite, limestone, concrete, etc.) coarse, medium, fine, widely used in a variety of ore crushing, railway, highway, energy, cement, chemical, construction and other industries. Its nesting stone size can be adjusted, crushing specifications diversification, great crushing ratio, high crushing efficiency, easy maintenance characteristics of the finished products are cubic, is ideal senior road surface and hydropower construction aggregate processing equipment.
Coal Crusher Performance and Use:
Coal crusher appears a little late,while it develops very rapidly. At present, it has been widely applied to medium crushing,fine crushing,also coarse crushing in cement, building materials, coal,chemical industry and mining.The reason why coal crusher develops so rapidly is for the following advantages:
High crushing ratio:the crushing ratio of coal crusher is about 30-40,even the max can be 150.While the max ratio of other crushers is less than 10.
Therefore, for the present popular three-stage crushing plant,if using coal crusher in it,there will only need one-stage or two-stage to finish the crushing,which greatly simplify the production process, save investment.
High crushing efficiency, low energy consumption: for impact strength of normal stuff is far lower than compressive strength,at the same time, when stuff is impacted by high-speed hammer and impact plate,stuff is crushed firstly along the joint interface and weak&vulnerable organization.Therefore its crushing efficency is high and electric energy consumption is low.
Homogeneous final product size,less excessive comminution.In the crushing process, larger stuff is crushed to a great extent, while smaller one is not crushed under some circumstances,so there is homogeneous final product size and less excessive comminution.
Selectively crushed. In the impact crushing process,useful minerals and gangue are firstly crushed along the joint interface in order to facilitate the separation of useful minerals,especially for coarse crushing of useful minerals, which is more remarkable.
Great adaptability. coal crusher can be used to process brittle stone,fibrous stone and medium hard stone,particularly suitable for brittle stone such as limestone,so it is proper to use coal crusher in cement and stone industry.
Small size, light weight, simple structure, easy maintenance.
For the above advantages,coal crusher is widely used all over the world.However if to process hard stone,the hammer and impact plate will be badly worn. In addition,coal crusher is a crushing equipment making use of high-speed rotation and impact,so it has high requiremnts for precision of mechanical parts, and also for static balance and dynamic balance in order to extend the service life.
Coal Crusher Accessories:
The Crusher Parts strict implementation of the heat treatment process, the use of high strength wear parts, key components Torrington bearings and other countries to export exemption product, device one-time investment, and effective.
Coal crusher counterattack board cast in ZGMn13-2 material. Casting after pouring water toughening treatment. Water toughening treatment after casting With high tensile strength, toughness, stone and non-magnetic. Makes the tooth plate more durable. Use of the process by the surface hardening, the deformation of the severe shock and strong pressure, and martensite is formed, thereby forming a high abrasion resistant surface layer, while the inner maintaining excellent toughness even wear to the thin, can also be withstand greater shock load.
Welded rotor body, spindle and rotor body taper sleeve keyless coupling, disassembly, easy to replace, with overload protection role.
Board hammer is a core component of the heat treatment process using special materials processing, both to ensure wear-resistant, and guaranteed not to break the life of ZGMn13 3-5 times the board hammer symmetrical production, can turn around and flip use, material utilization 50 % -60%, another plate hammer wear blocks easily and quickly fixed, embedded into the rotor body, the operation of automatic centering, installation, replacement.
Usage and Maintenance:
In normal use, the operator adjusts the radial clearance between impact plate and hammer mainly according to wear pattern of hammer and final product size. With hammer worn,the final product will be gradually coarse. At present, our hammer and impact plant is made of high manganese steel.
In addition, the bearing of coal crusher should be installed strictly in accordance with our factory’s regulation,checking and adjusting the clearance of bearing and lubricating device,timely replacing sealing ring in order to ensure the normal operation of bearing.
