Hammer Crusher is widely used in mining, cement, coal, metallurgic, construction material, road building, and Petroleum & Chemical industries. It is used for grinding the medium-hard materials. The material will be grinded by the striking between high-speed hammer and material. It possesses qualities of simple structure, large reduction ratio, and high-efficiency. Both Dry and Wet Process are available.
Hammer Crusher Operating principle:
The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.
The hammer crusher (hammer mill) has good quality features like simple structure, high reduction ration, high efficiency, and etc. The pc hammer crusher (hammer mill) is suitable for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum & chemical industries. Operating principle of hammer crusher: The motor drives the rotor rotated of the hammer crusher at a high speed through the belt, and on the rotor there are series of hammers. When the materials get into the working chamber of hammers, they are crushed by the rotating hammers with high rotation speed, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, while the large size products are brought back to the crushed area by the hammers for being recrushed until they reached the required size. In bulk or container.

Hammer crusher is mainly applied to low abrasion materials with medium hardness and compression strength not exceed 100Mpa. Such as coal, salt, chalk, gypsum, bricks, tiles, limestone, etc. It is also used to crush wood chips with strong fiber structure and tenacity, and the waste from asbestos cement to recycle asbestos fiber, etc. In addition, hammer crusher can be not only applied in crushing line and sand production line, but also applied instead of cone crusher. Performance and features: Hammer crusher has the advantages of high product capacity, high crushing ratio, low power consumption, uniform products partial size, simple structure, compact and light, low investment cost, easy to management, etc. The defects are: when crushing very hard materials, it will cause greater wear of hammer and grate and consume more metal; it needs more maintenance time and uniform feeding of materials; when crushing soft-moist materials, the capacity will become significantly lower and even stop because of material jam. In order to avoid jam, the moisture content of materials should be less than 10%-15%. Model PC400x300 Rotor diameter (mm) 400 Rotor length (mm) 300 Rotor speed (r/min)1100 Max. feeding size (mm)

Description: Ring hammer crusher is a punching rotor type crushing machine with ring-hammer on the rotor. The material is firstly crushed by the punching force of the high speed ring-hammer rotating, then the crushed material is thrown forward to crushing board for the second crushing, required sizes material will get out through the sieve plate, but bigger sizes material will be shot back to the ring-hammer again for the third crush. Such process repeats until the materials are crushed to the required size. Applied scope: ring hammer crusher is suitable for many departments, such as mine, cement, coal, metallurgy, building material, highway, burning material and so on. The solid material with medium hardness brittle material¡¡¥s fine crushing is available from ring hammer crusher. Besides, ring hammer crusher can be used widely to meet customers different requirement of different product size by adjusting the gap between grates.
