Hammer Crusher

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.

The hammer head is made of AMC composite material which is at international level and is developed by our company independently. The life of super hammer head branded as "Big Gold Teeth" is 50-150% longer than that of hammer made from Mn18Cr2MoNbRe. The reconstruction of crushing cavity with our patent of "stone strike stone" greatly increases the self-breakup rate of stones, which efficiently reduces the load of grate-shoe and hammer head. The technology of WHM two-step super hard surface interspersed welding is introduced for the rotor. The life of weld beadis over two times than that ordinary anti-abrasion welding rads. The main shaft is made of military gun steel with high strength the steel is made by means of vacuum double refining, whose strength is 4-5 times higher than that of ordinary shaft. New design of grate-shoe. The shones flow smoothly and stably. The size of stone is fine and even. The life of wall plate is long. Features Stones stricken by stones crushing cavity Hammer head is wearable Intensity of principal axis is higher Discharging granularity is fine and equality Easy maintenance Relialbe operation.

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. Characteristics: The characteristics of simple structure, easy maintance make ring hammer crusher sell abroad, and be appreciated by

Processing ability: 30-160t/h Max feeding size: 800mm Product Fineness: 0-50mm Range of application: Almost all minerals, such as quartz, feldspar, mica, calcite, gypsum, fluorite, limestone, soil, clay, marble, granite, pebble, coal, slag, iron ore, copper ore, manganeseore, refractory material, glass, etc. Brief Introduction of Cabinet hammer crusher: Cabinet hammer crusher with feature of large feeding space, it is very suitable for processing big raw material with size 450-1400mm to small granularity below 100mm, which are widely used for mine, cement, building material, chemical industry and so on. It is suitable for crush raw materials with compression strength not more than 200Mpa, such as limestone, rock, plaster, coal gangue etc. Working principle of Cabinet hammer crusher: In cabinet hammer crusher gravity, hammers do high-speed circular motion along with rotors driven by motor. After being fed into crusher, large stones are stacking on the shelf which is particular to box crusher. Raw materials are smashed into smaller pieces by hammers. Right following the fist crushing, unqualified pieces hit against the impact plate with new fed material at a tangent to circular motion of Hammers. So once for all, material undergo two steps of crushing, from coarse to medium size then to qualified small size. Finished product are sieved through screen and discharged at a uniform particle size. Benefit of Cabinet hammer crusher 1.Large feeding size, high crushing ratio, uniform particle size, 2.The finished size can be adjusted, high productivity. 3.Durable hammers, turning type cabinet, easy maintenance. 4.Coarse and medium reduction in one time, which simplified sand-making process.

Processing ability: 5-30t/h Max feeding size: ï¼?350mm Product Fineness: 5-30mm Range of application: Almost all minerals, such as quartz, feldspar, mica, calcite, gypsum, fluorite, limestone, soil, clay, marble, granite, pebble, coal, slag, iron ore, copper ore, manganeseore, refractory material, glass, etc. Brief Introduction of PC Hammer Crusher: PC Hammer crusher is equipment using high-speed rotary hammers to crush materials, mainly applied to the industries of metallurgy, mining, chemistry, cement, construction, refractory materials and ceramics. It can crush hard and soft ores into medium or small size, such as barite, limestone, gypsum, terrazzo, coal, slag, and up to 100 different kinds. Working Principle of PC Hammer Crusher: PC Hammer crusher mainly consists of frame, rotor, support iron and grate bars. The frame is divided into two parts: upper part and lower part which are welded by steel plates after being cut. Liners made of high manganese steels within the frame can be replaced after being worn out. The rotors consist of the turn plate, pin shafts, and hammers which are grouped regularly in the main shaft. The motor drives the rotors to rotate quickly in the crushing cavity, and hammers spread outward as a result of centrifugal force from the rotation of the rotors. Large materials entering the crusher through the feed inlet are stricken, impacted, cut and ground by the high-speed hammers to small size. Qualified materials crushed will be screened out and exit from the gap of the grate bars while the unqualified will be left in the crushing cavity to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the grate bars. The gap between the rotors and the grate bars can also be adjusted according to different requirement. Benefit of PC Hammer Crusher: 1.high capacity, high crushing ratio 2.uniform particle size, simple structure 3.Low investment, easy management and maintenance.

Diesel Engine Hammer Crusher The small diesel hammer crusher is also called diesel hammer mill, which is equipped with diesel engine instead of electric motor. It is suitable for crushing medium hardness and fragile rocks, such as limestone, coal, salt, gypsum, brick, tile, etc. Diesel Engine Small Crusher Features: 1. Suitable for middle and fine crushing of different sizes of materials. 2. Low investment, the diesel engine is cheaper than that with electric motor 3. Equipped with two wheels, which is a perfect choose for outdoor operation 4. Simple structure, easy to operate and maintain Working Principle : Driven by the diesel engine, the rotor rotates at a high speed and there are series of beaters on the rotor. When the raw material get into the working area of beaters, it will be continuously impacted by the rotating hammers. The impacted particle meeting the required size will be discharged from the outlet, and the big size material is brought back to the crushing area for re-crushing until reaching the required size.
