Impact Crusher is mainly used in metallurgy, chemicals, building materials, utilities and other materials often need to move processing operations, especially for highways, railways, hydropower engineering and other stone work flow. It can be different depending on the type, size and processing of raw materials finished material requirements using a variety of configurations.
Development History Of Impact Crusher
Impact crusher development history can be traced back to the 1850s, from the birth of the first jaw crusher in the world for a long time has passed. With the development of productive forces, jaw crusher has been unable to fully meet the needs of crushing technology, so, on the basis of the jaw crusher, it has designed a Impact Crusher.
In 1924, the German first developed a single, dual-rotor two types of Impact Crusher, when the crusher structure similar to the modern squirrel cage crusher, because in terms of structure, or from the working principle analysis it has all the characteristics of the Impact Crusher. As the material requires repeated impact, crushed process can be free and unimpeded discharge, but due to the strength and limits feed Impact Crusher capacity, which gradually transformed model for squirrel cage crusher.
In 1942, German Andreson summarizing the structural characteristics of the squirrel cage crusher hammer crusher and working principle based on the invention is of the modern and Impact crusher structure similar to the AP series impact crusher. Thanks to the productivity of this Impact Crusher is relatively high, can handle larger material, and it is relatively simple in form structure, easy maintenance, so, this Impact Crusher has been developing rapidly. With the further development of the crushing and screening crushed theory has improved steadily and technology, a variety of high-performance Impact Crusher endless.
Until the late eighties China has introduced KHD-type hard rock impact crusher, fill the gaps, but behind twenty years abroad. Domestic hard rock impact crusher, the beginning of its core parts board hammer dependent on imports, and domestic plate hammer "eight five" period as a ministerial-level scientific research projects, after the success of the project, the domestic plate hammer not only replace imports, and has been exported Europe, Japan and other countries. Breakthrough wear-resistant materials, to make even more powerful hard rock impact crusher. For example: the Ministry of Communications to improve the quality of highway construction, concrete pavement research projects have been proposed stone crushing plant, and included in the national "eight five" key project. Trial equipment failure in the northeast of the project site for a use. After the user to switch to hard rock impact crusher stone production, in full compliance with the highway anti-skid pavement concrete requirements. So hard rock impact crusher reputation has been boosted.
National economic development must be to promote the rise of some of the infrastructure, the construction of the infrastructure into a boom, so in this context, it is bound to promote the progress of China's mining machinery market. Based on the stringent requirements for construction sand, but also to open up a broader market, the new HCP, HCS efficient Impact Crusher, sand and gravel used in a full set of hardcover production line for advanced crushed, with the normal operation of the entire production line.
- the rotor backplane can withstand extremely high moment of inertia of the rotor and the impact hammer crushing force;
- designed to be optimized low-speed, multi-impact crusher crushing chamber, the impact crusher than the average line speed reduced by 20% -25%, with low power consumption for high production capacity;
- It has tertiary crushing and shaping functions, thus crushing ratio, cubic shape products, selectively crushed, etc;
- Unique counter tooth plate, keyless connection, easy maintenance, economical and reliable;
- impact crusher is equipped with multi-function hydraulic station, with high-speed hydraulic discharging gap, the back plate and the body automatically open stable damping and other functions.
Advantage Of Impact Crusher
1, Impact crusher to deal with large amount of wet material is more effective and effectively prevent the material from clogging. In dealing with excessive moisture content of materials, Impact Crusher feed chute and the back plate can be equipped with heating means, to prevent the adhesive material. Impact Crusher shall not be equipped with the bottom of the sieve can effectively prevent clogging.
2, the Impact Crusher is suitable hardness of the material more widely. Impact Crusher board hammer mechanical clamping structure firmly fixed on the rotor, with a great moment of inertia when the rotation with the rotor. With respect to the hammer crusher (hammer was hanging state), rotor Impact Crusher has a greater momentum, crushed harder to adapt to the material, while their low power consumption.
3, It can be convenient and flexible to adjust the particle size, wide adjustment range.Impact Crusher through a variety of ways to adjust the particle size, such as adjusting the rotor speed, adjusting the gap between impact plate and grinding chamber and the like. Gap adjustment can be adjusted by mechanical or hydraulic, hydraulic system can be easily adjusted by an operator or fortune-place control systems to complete the adjustment of the gap.
4, Wearing parts wear small, metal utilization. Impact rock breaking machine board hammer wear only appear in the Looking to material side. When the rotor speed is normal, the feed will drop to the surface of the plate hammer, hammer the back and side panels are not being worn. Even Looking to material this side rarely wear. And the bottom of the grinding rod is also very easy to replace. Impact Crusher hammer metal utilization can be as high as 45% -48%.
