Equipment Introduction 

Impact crusher is a device that uses impact to crush materials, with advantages such as high crushing ratio, uniform product particle size, low energy consumption, wide range of product particle size adjustment, and selective crushing. 

Working principle and structural characteristics 

Impact crusher is a type of crushing machinery that uses impact energy to crush materials. When the material enters the crushing chamber, it is selectively crushed by the impact of the high-speed rotating hammer head; The material gains tremendous kinetic energy from the impact process and is thrown at high speed towards the first stage counterattack plate. Due to the counterattack effect of the counterattack plate, the material is broken again, and the material bounced back by the counterattack plate is again impacted by the hammer head, continuing the above crushing process; Afterwards, the crushed material is also thrown at high speed towards the second stage counterattack plate, further achieving crushing; In this way, the material is continuously subjected to multiple impacts from the plate hammer and counterattack plate, as well as the mutual collision between materials, resulting in cracks, looseness, and fragmentation along its own joint surface; When its particle size is smaller than the gap between the hammer head and the counterattack plate, it is unloaded from the lower part of the equipment.

Feature and advantages of impact crusher 

1. Multi-cavity uniform crush is suitable to crush hard rocks. 2. The leveling plate make discharge material at finer and cubic shape without internal cracks. 

3. The low and large feed opening is suitable for production line arrangement and to increase feeding size. 

4. Full hydraulic type opening is suitable for maintenance and replacement of wear part. 

5. New abrasive material makes impact hammer board, impact plate and liner have long working life. 

Structural composition and characteristics 

The impact crusher is mainly composed of a frame, transmission mechanism, rotor, hammer head, impact plate, etc. Its main structural characteristics are: 

1.Rack: composed of upper and lower parts, connected by bolts; All parts of the rack that come into contact with crushed materials are equipped with replaceable lining plates, and chain curtains are installed at the feed inlet to provide safety protection;

2. Transmission mechanism: The main shaft and rotor are driven by an electric motor through belt transmission for high-speed rotary motion;

3. Rotor: Made of integral cast steel structure, it has high quality and durability, and is also easy to install hammer heads; 

4. Counterattack board: made of new wear-resistant materials, freely suspended inside the equipment; 

5. Hammer head: Made of a new wear-resistant material, it is fixed on the rotor through a wedge block. The impact crusher from 西瓜影视.,Ltd plays an important role in various industrial fields through its unique design and efficient process flow, Especially for materials that can be crushed and have a compressive strength not exceeding 320Mpa, it is particularly outstanding in the application scenarios of producing triple materials for high-grade highways, hydropower, construction and other industries.
