Impact Crusher Working Principle

Impact Crusher Working Principle

Impact crusher is widely used in various kinds of hard and brittle materials such as rock, abrasive, refractory, cement clinker, quartz stone, iron ore, concrete aggregate, etc. Sand and road sand are particularly suitable. The impact crusher has simple structure, low price, stable operation, high efficiency and energy saving. The material self-lining in the impeller and vortex crushing chamber greatly reduces the wear parts cost and maintenance workload. The impact crusher effectively solves the raw materials such as glass. The problem of “iron pollution” in the crushing process and the “calendar steel” problem in the process of steel slag crushing, the ingenious internal airflow self-circulation eliminates the dust dispersion.

Factors affecting production capacity

Generally speaking, there are many factors affecting the production capacity of the impact crusher. Generally speaking, there are five factors. The following five factors will be described and corresponding solutions will be proposed.

1. Hardness of material: The harder the material is broken, the more difficult it is, and the more serious the wear of the equipment, the slower the breaking speed and the lower the capacity. Therefore, we need to pay attention to the selection of materials.

2, the composition of the material: before entering the impact crusher, the more fine powder contained in the material, the more impact on the crush, because these fine powder is easy to adhere to affect the transport, so the material with a lot of fine powder should be sieved one time in advance, will Fine powder should be screened out from the material as much as possible to avoid affecting the normal operation of the impact crusher.

3. The fineness of the material after crushing of the impact crusher: the fineness requirement is high, that is, the finer the material is required to be broken, the smaller the crushing capacity is. The specific requirements are determined in this respect. If there is no special requirement, the general will The fineness of the material can be set to medium and fine.

4. Viscosity of the material: the greater the viscosity of the material, the easier it is to adhere. The material with high viscosity will adhere to the inner wall of the crushing chamber in the impact crusher. If it cannot be cleaned in time, it will affect the impact crusher. Work efficiency, in severe cases, may also affect the normal operation of the impact crusher. Therefore, when selecting materials, it must be noted that the viscosity of the materials is not too large.

5. Humidity of material: When the moisture contained in the material is large, the material is easy to adhere in the impact crusher, and it is easy to cause blockage during the feeding process, resulting in a reduction in crushing capacity. To solve this problem, we must first strictly control the humidity of the material when selecting materials. If the humidity of the selected material is too large, we can use sunshine or air drying to reduce the percentage of moisture in the material.

Impact crusher is easy to repair

In view of the maintenance problems that many users purchase the impact crusher, the manufacturer pays special attention to this problem when designing the impact crusher. The impact crusher we designed is mainly composed of feed port, distributor, overflow, impeller, crushing chamber, counterattack plate, main shaft, frame, motor and other components. It has the characteristics of reasonable structure and stable operation. If there is a fault in operation, the customer can open the observation door to check the internal condition of the equipment, adjust the various parts of the equipment as appropriate, and our technical staff will train the basic operation and maintenance skills. If there is any problem that you can't solve, please call our company after-sales service. Our equipment is a lifetime warranty, we are happy to serve you.

Impact crusher working principle

The material enters the impact crusher from the feeding hopper, and the material is divided into two parts through the feeder, and a part of the material enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller, and its acceleration can reach hundreds of times of gravity acceleration. And then ejected from the three uniformly distributed flow paths of the impeller at a speed of 60-70 m/sec. First, it is impact-broken with a part of the material falling from the periphery of the distributor, and then impacts together on the material lining in the vortex cavity. It is rebounded by the material lining, impacts obliquely upward to the top of the vortex chamber, changes its direction of motion, deflects downward movement, and the material emitted from the impeller flow channel forms a continuous material curtain. Such a material is subjected to two or even multiple chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge port. It forms a closed circuit with the circulating screening system. Generally, the material can be broken into 20 mesh or less after three cycles. During the whole crushing process, the materials are crushed and broken by themselves, and are not in direct contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces pollution and prolongs mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.
