Impact hammer crusher basic structure to determine the parameters

1 the diameter and length of the rotor
The diameter of the rotor body and maximum feed size information. According to the impact theory, particle size and feed hammer proportional to the mass, and with the hammer

effectively combat height (ie the height of the rotor body exposed hammer) are closely related. In addition, taking into account the impact hammer crusher machine work process there is

a certain role when rolling, turning their anger must have sufficient capacity, which requires the diameter of the rotor body with feed particle size increases.

Typically, the diameter of the rotor body and the ratio of the maximum feed size is 2 ^ -4, take small mainframe. The length of the rotor is taken according to the production

capacity of a given size.

Hammerhead
a. hammerhead hammerhead shape and the height of the rotor is exposed h.

Design, hammer face should in principle be the rotation axis of the rotor in order to achieve a positive impact on the material hammer. Taking into account the wear compensation

or hammer weight restrictions, a slight deviation. Hammerhead ends arc surface design should consider the introduction of bite angle a. This paper recommends a 5-100. Too large

bite angle so that the hammer premature wear and reduce the life of the hammer. The arc length is mainly based on the type of hammer weight required strength corresponding

hammer shaft diameter, and take an arm fixed thick. Hammer shaft and arm strength assessment can hammer in working condition in equilibrium when the force is calculated, and

when working with hammer centrifugal force as the payload checking.

Hammerhead exposed rotor body height h that is highly effective in combating the hammer. From the point of impact mining screen effects and hope h large production capacity, especially for

bulk materials, to achieve the desired impact, h is bound to large, in theory, if the force of the impact gob gob right through the center of gravity. Then shocks the best

results. Consideration to the structural design is reasonable, and the power consumption increases, the person must be properly increased. At the same time people can not be too

small, too small h increased the hammer on the material increases the abrasive cutting, it will affect the handling capacity of the crusher exacerbated hammer wear.
