PF Impact Crusher

Impact crusher is a new generation crusher which is developed by our company in absorbing domestic and foreign advanced technology, combining with the concrete industrial conditions of domestic sand and gravel industry.Impact crusher is a new type of high efficiency of crushing equipment, its characteristics is small size, simple structure, big crushing ratio (up to 40), low energy consumption, large production capacity, product size uniform, and selective crushing effect is very promising devices. But its biggest weakness is that the hammer and the counter plate is particularly easy to wear, especially the broken hard ore, wear is more serious, need to often change. At present, due to the emergence of some wear-resistant material, in some metal concentrator has been applied.

Impact crusher mainly by impact principle to achieve the selective crushing of material, and therefore the products out of its production of grain shape, high pass rate, is often used as requirements on aggregate crushing stage of high subgrade and pavement, can also be used in building materials, chemical industry, mining and other industries of the crushing production process. It is mainly with high rotating hammer impact block, the weak layer selectively broken, is the impact of the material obtained tremendous kinetic energy. After counterattack plate and the material between the mutual collision and friction and achieve further broken until screened qualified products.

Development of PF Impact Crusher

  1. The need of the existing structure of impact crusher was improved to increase the impact crusher on the hard ore crushing capacity and equipment maintenance convenience, which are mainly concentrated in the improvement of the plate hammer, rotor structure to facilitate the replacement of the plate hammer and clamping; counterattack frame (crushing cavity shape) structure optimization, improve ore a breakage rate and energy utilization rate.
  2. The research and development of the new type of plate hammer with high wear and toughness can improve the service life of the hammer and increase the productivity.
  3. Application of electromechanical integration of modern technology and modern control methods, such as hydraulic technology, electronic technology, and constantly improve the automation degree of impact crusher, reduce the labor intensity of workers, improve the productivity. For example, the structure parameters of the counter frame are optimized by modern computer aided design, which improve the utilization of energy and the crushing rate of the ore.
  4. In order to meet the needs of the market and customers, the counterattack crusher is a series of standardization, and the development of large-scale.
  5. Adhere to technological innovation, and gradually get rid of the single introduction and imitation of the product.

The production line of sand production line is essential to impact crusher

National high-speed iron ore aggregate supply need to rely on the support of the crusher and other mine equipment. 2012, the technology innovation of high-speed railway is developing to more fields, and the pursuit of speed and the innovation of technology are endless.In sand production line is generally used for coarse crushed is jaw crusher, for secondary crushing is impact crusher, for crushing is cone crusher and, of course, for other occasions to roll crusher, composite crusher, crusher equipment.

But general secondary crushing are selected crusher, because without it, is counterattack type crusher is a new type of high efficiency of crushing equipment, its characteristics is small size, simple structure, big crushing ratio (up to 40), low energy consumption, large production capacity, product size uniform, and selective crushing effect, deal with side length 100-500 mm to material, with compressive counterattack crusher machine to a maximum of up to 350 MPa, with big crushing ratio, broken material after a cubic granule advantages, so in the line of psammophytic, counter type crusher in arenaceous product line is secondary crushing of choice.
