Hammer crusher (sand breaker) is a one-stage crusher that directly crushes materials with a large particle size of 600-1800 mm to below 25 or 25 mm. Hammer crusher box body, rotor, hammer head, counterattack lining plate, sieve plate and so on. Mainly used for crushing medium hardness materials in cement, chemical, electric power, metallurgy and other industrial sectors.
Application areas: limestone, coal, salt, white Asia, gypsum, alum, brick, tile, coal gangue, etc.
Equipment advantages: 1. Large crushing ratio (generally 10-25, the highest is 50), high production capacity, uniform product, less over-crushing phenomenon, and low energy consumption per unit product.
2. It is suitable for crushing various medium and brittle materials.
3. The hammer crusher has compact structure, reasonable layout, convenient installation, good maintainability and easy operation.
4. The raw materials of different sizes can be crushed into uniform particles to facilitate the processing of the next process. The mechanical structure is reliable, the production efficiency is high, and the applicability is good.
Working principle: Hammer crusher mainly relies on impact energy to complete the operation of crushing materials. When the hammer crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head rushes to the baffle plate and sieve bar in the frame, and the material larger than the sieve hole size is blocked on the sieve plate and continues to be hit and ground by the hammer until it is crushed to the required discharge size and finally discharged out of the machine through the sieve plate .
