subject: Hammer Crusher Working Principle [print this page] The hammer crusher can be divided into two kinds: the reversible and unreversible. And the motor of the reversible hammer crusher can be reversible, which can be used for fine crushing while the unreversible hammer crusher can not be reversible, which can be used for medium crushing. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are crushed to small sizes by the high-speed hammer, with the process of pressing, impacting, cutting and grinding. There is a screening plate under the rotor, which make sure the materials with size smaller than the screen mesh will be screened out and others will be left to be further hammered and ground until they fulfill the standard size. The size of the final products can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirements.
Technical Features of Hammer crusher
1. Side liners - modular design, available in optional grades and easy to install.
2. Hammers available in a range of materials to suit specific applications. Modular concept means minimal on site stock holding over complete range.
3. High inertia rotor with heavy duty backing bars and unique wedge lock system allowing vertical removal of hammers.
4. Individual curtain adjustment (hydraulic) with easy locking.
5. First curtain liner with modular concept heavy duty liners. All curtain liners are interchangeable.
6. Second curtain liner separately adjustable for accurate product sizing.
7. Third curtain adjustment, easy access and adjustment.
8. Third (optional) curtain liner, ideal for finer product sizing and most recycling operations.
Hammer crusher is mainly broken by the shock effect to the material.The crushing process is roughly like this, the material into the crushing machine, suffered the impact of high-speed rotation of the hammer and broken, broken materials, obtained from the kinetic energy of the hammer from high-speed toward the frame body baffles, sieve of, at the same time the material of conflict, have been repeatedly broken, the gap is less than the screen of the material discharged from the gap, the larger the individual materials in the screen bar again by the impact hammer, grinding, squeezing and crushing, the material was hammer out from the gap thus obtained the required size of the product.
