Description of Hammer Crusher
Hammer crusher produced by Shanghai Dingbo Machinery is the equipment using the high-speed rotary hammer to crush materials, hammer crusher mainly applied to the industries of metallurgy, mining, chemistry, cement, construction, refractory materials and ceramics. Hammer crusher 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.The compressive strength of the materials do not exceed 100MPa and humidity islessthan15%.
Hammer crushers' features:
1 Hammer head, adoption of new casting technology, has wear-resisting and impact resistance.
2 Adjusting the production granularity according to customers' requirements.
3 Adopting the seal body structure in order to solve the dust pollution and ash leakage problem of the workshop.
4 One of the upgrading products and the overall design is of attractive appearance, compact structure, less wearing parts, easy maintenance.
Working principle of hammer crusher
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.
