Crusher 25 X 15
Crusher 25 X 15 Introduction:
Crusher 25 x 15 (referred to as the back-breaking) and hammer crusher belong to impact the role of the main machine to crushing brittle materials, also called crusher 25 x 15. 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.
Crusher 25 X 15 Working Principle:
Crusher 25 x 15 is a use of impact energy to break material crushing machinery.When the unit is operating, the motor driven rotor high-speed rotating materials into the active area of the plate hammer, impact crusher plate hammer on the rotor, and later was thrown counterattack device again broken, then from counterattack linerbounced back to the the board hammer district re-broken, and this process is repeated, the material descending into one, two, three, fight back cavity repeated broken until the materials are crushed to the required size of the discharge port. Adjust the gap between the frame and the rotor counterattack up to change the purpose of material discharging size and material shape.
Crusher 25 X 15 Advantages:
Crusher 25 x 15 is developed on the basis of absorbing domestic and foreign advanced technology, combined with domestic the gravel industry specific mining conditions, the latest generation of crusher 25 x 15. It uses the latest manufacturing technology, the choice of high-quality, high-chromium plate hammer, wear counterattack lining, plus a unique gear counterattack liner design, both to improve the impact of the equipment, but also enhance the wear resistance.
Crusher 25 x 15 through more optimized design, more crushing chamber, feeding greater granularity, new heavy rotor design, it has a greater moment of inertia, increasing the yield of the device, the more broken the ratio, in order to achieve a low-cost, energy-saving, efficient combination. Cubic shape of the finished product after processing, no tension and cracks, stone shape complete. Another compact structure, the fuselage using keyless connection, easy maintenance, more suitable to promote the use of large-scale.
Crusher 25 X 15 Performance and Use:
Crusher 25 x 15 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 crusher 25 x 15 develops so rapidly is for the following advantages:
High crushing ratio:the crushing ratio of crusher 25 x 15 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 crusher 25 x 15 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. crusher 25 x 15 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 crusher 25 x 15 in cement and stone industry.
Small size, light weight, simple structure, easy maintenance.
For the above advantages,crusher 25 x 15 is widely used all over the world.However if to process hard stone,the hammer and impact plate will be badly worn. In addition,crusher 25 x 15 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.
Crusher 25 X 15 Performance Characteristics:
1.Crusher can effectively deal with a large amount of material moisture, prevent crusher clogging. Processing materials excessive moisture, crusher 25 x 15 feed chute and counterattack board can be equipped with a heating device to prevent the adhesion of the material.
2. The crusher 25 x 15 applies to both the soft materials and suitable for very large hard materials. The plate hammer Crusher mechanical clamping structure is firmly fixed on the rotor, when the great moment of inertia with the rotor rotates. Relative to the hammer crusher (hammer was hanging), crusher 25 x 15 rotor has greater momentum adapt crushing hard materials, while the energy consumption is lower.
3. crusher 25 x 15 can be convenient and flexible adjustment of feed size, wide range of adjustment. Impact Crusher through a variety of ways to adjust the particle size, such as the regulation of the rotor speed, adjust the counter plate and the grinding chamber gap. The gap adjustment can be adjusted by a mechanical or hydraulic.
4. Crusher wearing parts wear than small hammer crusher, high utilization of metal. Counterattack crusher plate hammer wear only Looking materials side. Normal rotor speed, feed plate hammer will fall to the surface (of attack), the plate hammer back and sides are not to be worn. Even Looking material side wear very little. And the bottom of the grinding rod is also very easy to replace. crusher 25 x 15 board hammer metal utilization rate can be as high as 45% -48%. Hammer crusher hammer was hanging, wear and tear occurs in the upper, front, rear and side, relative to the plate hammer, hammer wear more serious hammer metal utilization ratio is only 25%, and the rotor body may be subjected to wear.
5. Crusher spare parts easy to replace, and a corresponding reduction in maintenance costs. Just one shift only install six board Hammer Crusher rotor can easily board hammer replacement, replacement of a board hammer time. The bottom of the grinding chamber grinding rod replacement requires only tens of minutes can greatly reduce the time and cost of repair and maintenance.
