Hammer crusher is a one-stage crushing machine used for directly crushing the materials whose biggest granularity is 600-1800 mm to 25mm or smaller. It is suitable for the medium and fine crushing of medium hard materials such as limestone, coke, slag and coal in cement, chemistry, power, metallurgy and other industrial departments. Hammer crusher hammer rotor, spindle and bearings, pin, hammer frame and wheel components.
First, hammer shape and quality
1) hammer crusher hammer and crushing the material properties of the shape and size related, that is crushing the material with the hardness, brittleness, size and other factors.
2) The hammer-shaped shape and quality; one more severe; second is to extend the life of a hammer.
Second, determine the location of the hammer pin hole
Although the rotor hammer crusher rotor balancing requirements met, but a hammer hanging incorrectly, that the pin hole with a hammer will not impact on the material, the pin, shaft and bearing against an impact force.
In order to work crusher, hammer pin does not produce the reaction, must be under the impact hammer is equilibrium. The so-called equilibrium, that is, the impact hammer material, the suspension does not have an impact on the pin reaction force. Indeed, it is the right choice pin hole location. For medium and fine crush, there are many types of crushers, such as jaw crusher, cone crusher, hammer crusher, impact crusher, roller crusher, high pressure roller mill.
Third, determine the quality of the hammer
Hammer crusher hammer is the most critical parts, and a hammer the size of a direct impact on the quality of the crushing effect. If the quality is too small hammer, break the material does not meet the requirements of time; if the quality is too large a hammer, then the consumption of too much exercise in futility, not economic. Part by the rotor shaft to support the spindle and bearings installed in the rack in the wall flow. Broken boards The impact of the work force but also by the spindle bear, therefore, requires the spindle material has high strength and toughness. Spindle with a square cross-section of circular cross-section and two, which is the hammer frame looper not flat key in the spindle connection.
