Impact crusher is short for impact breaker, and it is commonly known as the sand making machine. It is a kind of energy consumption impact which has the international advanced level. Its performance plays an irreplaceable role in all kinds of ores and fine broken equipment. Due to these, it has become the most effective, practical and reliable gravel machine currently.

The working principle of impact crusher , the simple point is the principle of stone dozen stone. Let the pebble collided and pass the impeller accelerate out of stones in the natural process of falling in order to achieve the purpose of breaking. While being accelerated stones and falling thrown stones collision naturally when the formation of a vortex, the return process and two broken, the wear is very small in the process of operation of the machine back plate.

The stone falls into the high-speed rotation of the wheel directly from the upper part of the machine, in the high speed under the action of centrifugal force, and the other part of the umbrella type approach to producing high speed flow in the wheel around the target of stone impact and high density of crushing, stone in the fight against each other, will form a vortex motion between the turntables and the chassis caused by repeating against each other, rubbing, grinding, discharging from the bottom directly. The formation of many closed loop control achieve the required size by screening equipment.

The impact crusher’s structure is novel and unique. It has low energy consumption, high yield, high crushing ratio and small volume. In addition to these, it is convenient to install, operate and repair. Stone can be formed to protect the fuselage bottom, no wear, durable in the course of production process.

This is not only a new development of the ninety's in the fine crushing equipment，but also the world widely used instead of cone crusher to roll machine models. The impact crusher has finely, coarse grinding function and high efficiency. Its products are excellent. Their shapes are cube, extremely low flakiness content. It is suitable for the production of plastic, artificial sand and aggregating in high grade highway. Its products have high packing density and their iron pollution is minimal. A few easy wear parts are made of very hard wear-resisting material. They have small volume, light weight. Besides，they are easy to replace.

Impact is widely used in all kinds of metal and nonmetal ore, cement, refractories, abrasives， glass raw materials, construction aggregate, sand, metallurgical industry. Application of fine different hardness of various minerals and rocks, s uch as high hardness materials, iron ore, non-ferrous metal ore, carborundum, bauxite, quartz sand, perlite, Zong Gangyu, Xuan Wuyan and other finely homework, are the domestic construction, mining and metallurgical industries, highway, railway, bridge, hydropower, mineral grinding field and mechanism of the core equipment of sand industry.
