Impact crusher, also known as impact crusher, vertical impact sand making machine and impact sand making machine, is composed of seven parts: feeding, distributor, whirling crushing chamber, impeller experience, main shaft assembly, base transmission device and motor. It plays an important role in the artificial sand production line, and is widely applicable to all kinds of hard Medium and fine crushing of brittle materials (making sand particles). It is suitable for building sand and road sand.

Compared with other types of crushers, impact crushers have the following advantages in the artificial sand production line:

1. The impact crusher has high crushing efficiency and has the functions of fine crushing and coarse grinding.

2. The impact crusher has the advantages of simple structure, convenient installation and maintenance, and low operation cost.

3. The ability to pass through non broken materials is strong, and it is less affected by the moisture content of materials, which can reach 8%.

4. The impact crusher has excellent particle shape, cube shape and extremely low needle and sheet content, which is suitable for aggregate shaping, artificial sand making and aggregate production of high-grade highways.

5. The product has high bulk density and minimal iron pollution.

Under the action of impact, the crushed materials tend to break along their most vulnerable layer. This selective crushing method has a high probability of dry cube shape of particles, so the percentage of needle and flake of impact sander products can be less than 10%, while the percentage of needle and flake of jaw, cone and roller crusher products will be higher than 15%. The above characteristics make the impact sand making machine play an important role in many crushing machines.

The impact crusher plays an important role in the artificial sand production line. Because a set of equipment for the sand production line is expensive, and if you want to produce a complete set of sand production line, you need certain technical and economic strength, especially for customers who want to buy a large sand production line first, you must choose a large manufacturer. The quality of the sand production line produced by a large manufacturer is guaranteed, and the production efficiency is also high.

The processing workshop equipment of the sand production line manufacturer. If the workshop equipment of the sand production line is advanced enough, the process and performance of the sand production line they produce will be relatively good, which will reduce a lot of expenses when the sand production line is put into later production.

Whether the sand making production line is complete? The sand making production line is composed of multiple equipment, so the manufacturer who chooses to cooperate should be able to provide a complete set of sand making production line, and do not buy a single equipment to piece it up. Because the pen performance and specifications produced by different manufacturers are different, it is difficult for these equipment to combine to give full play to the advantages and maximum capacity of each equipment, and cannot bring us high output and good benefits.

Working principle of impact crusher:

During the impact breaking operation, the material enters the crusher from the feed hopper, and is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. Its acceleration can reach hundreds of times the gravitational acceleration, and then it is thrown out from the three evenly distributed flow channels of the impeller at the speed of 60-70 M / s. first, it is impacted and broken by a part of the material collected and dropped around the distributor, Then they impact on the material lining in the vortex branch chamber together, rebound by the material lining, impact the top of the vortex chamber obliquely upward, change its movement direction, deflect and move downward, and the materials emitted from the impeller channel form a continuous material curtain. Such a piece of material is subjected to two or more times of probability impact, friction, grinding and crushing in the vortex crushing chamber. The crushed materials are discharged from the lower discharge port. It forms a closed circuit with the circulating screening system. Generally, the material can be broken into less than 20 mesh after three cycles. In the whole crushing process, the materials impact and crush each other without direct contact with metal components, but crush due to impact and friction with the material lining, which reduces angular pollution and prolongs the mechanical wear time. The ingenious air flow self circulation inside the whirling chamber eliminates dust pollution.
