Working principle and main characteristics of impact crusher

Impact crusher is used in the production of ore and sand production line commonly used crushing equipment, especially for sand making effect is very good, today we will come together to understand the principles and characteristics of such equipment.

1, the impact crusher working principle

Impact crusher is a new type of self Impact Crusher. The utility model is mainly composed of a feed hopper, a distributor, a vortex crushing chamber, an impeller body, a main shaft assembly, a base, a transmission device and a motor.

Impact crusher work, ore into the crusher cavity, the motor drives the crushing chamber of the impeller rotating speed, will stop falling ore thrown to the inner wall of crushing cavity, partial residence here, produce ore lining. The ore, which was subsequently thrown into the lining of the seam, was recovered, and the kinetic energy was fully transformed into the energy of the broken ore, which was broken for the first time. The process of ore rebound falling, and thrown out of the new ore impact, the second time being broken, even re impact to the ore lining cycle breaking process of new, finally through the discharge port. In this way, the whole ore will be impacted at least two times or more in the crushing process.

 

2, the main characteristics of impact crusher

(1) the impact crusher before use, with a certain amount of mineral products and a certain proportion of water needed, added to the impact crusher machine cavity, three cavity through the impeller machine Nene (head) of high speed operation, the dust particles stick and fine ore in finished products to pay, cavity metal element on the formation of a dense protective layer. In the process of crushing the ore is not in direct contact with the inner cavity of the metal element, but with the ore liner impact and collision and crushing, the crusher wall basically do not produce wear consumption, usually only in the middle rotating parts wear parts consumption, low consumption cost, maintenance workload is small, fast. The ores have been impacted by many times, the fine material reaches a high standard and the crushing efficiency is high. Compared with the relative cone, the water content of the ore is low, and the water content of the broken ore is usually less than 20.

(2) maintenance workload is small, low cost. Due to the special structure of the impact crusher, compared with the cone crusher, because there is no hydraulic system does not leak, reducing the equipment failure rate and maintenance personnel technical requirements. Impact crusher is the main wear parts of the three impeller (cutter head), put the heap, bread block long service life (each can be broken 4400 ~ 4800t ore), low cost (the cost of each wearing parts of about $3500). The replacement period of the wearing parts is long, and the maintenance time and work intensity of the equipment are reduced.

Impact crusher is widely used, is suitable for crushing a variety of ore crushing equipment, high production, maintenance workload is small, effectively reducing the intensity of work, you are welcome to come to consult the purchase.
