Adopting the latest manufacturing technology and unique structure design, the PF series impact crusher can produce cubic products with very good grain shape without tension and crack. It can crush each kind of coarse, medium, fine cubic material (granite, limestone and concrete etc) with feeding size not more than 500mm and crushing strength not more than 350MPa and is widely applied to secondary and tertiary crushing of various ores and medium- hard materials in railway, highway, energy, cement, chemical industry construction etc.

Impact Crusher is a kind of new type high efficiency crushing equipment. It has the features of small volume, simple structure, and big reduction ratio, high production capacity, production size well-distributed; also have the selective crushing effect. It is promising equipment. But its biggest drawback is the hammer and the back plate particularly easy to wear, especially when crushing hard rock, wear and tear is more serious, so it needs for frequent replacement. At present, in some metal concentrator has been applied, because the emergence of a number of wear-resistant materials.

In summary, the direction of crusher development mainly shows in the following areas:

We need do some improvements for existing crusher structure; improve the crusher on the hard stone crushing capacity and ease of maintenance. Mainly focus on improvement of hammer and rotor structure, in order to facilitate the replacement board and hammer mounted card, counter-attack aircraft (the crushing chamber shaped) structure optimization, increasing energy efficiency.

Research and develop new kind hammer plate material which is high toughness, high wear-resistant, and increase productivity.

Application of modern Mechanical technology and control methods (as Hydraulics and Electronics), continuously improve the crusher automation level; Reduce the labor intensity, productivity gain. For example, application of modern computer-aided design optimization of the structural parameters of counter frames Improve energy efficiency and broken rates of ore.

In order to meet market and customer needs, impact crusher is normalized to the series, large-scale development.

Adhere to technical innovation, gradually emerging from a single product introduction and imitation. Improve the crusher independent knowledge of the R & D.

When the impact crushing machine works, the motor drives the rotor rotate of the impact crusher with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers affect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being refreshed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet of the impact stone crusher and mineral impact crusher.

As the professional manufacturer of complete sets of mining machinery, such as stone production line,rotary dryers, Henan Hongxing is always doing the best in products and service.
