Factors affecting the  impact crusher crushing effect


Due to impact crusher simple structure and large crushing ratio, the impact crusher is widely used in building materials, highways, railways, mines and other industries. The factors affecting the impact impact are as follows:

1. Rotor rotation speed
Generally speaking, the higher the rotor speed is, the greater the impact force will be when the plate hammer and the material contact and collide. With the increase of the rotating speed, the greater the impact force will be when the material and the counterattack plate collide, the better the impact crushing effect of the material will be, and the higher the damage degree of the material will be.

2. Rotary inertia of the rotor
In the case of impact crushing of materials, the greater the rotary inertia of the rotor is at the same rotating speed, the greater the impact crushing force of the plate hammer on materials and materials and the counterattack plate will be. In the case of subsequent shear crushing of materials, the smaller the counterattack plate is affected by the reaction force of materials, and the easier it is to shear crushing of materials.

3. Strike board Angle at all levels
It is found that reducing the Angle of the first stage counterattack plate has a better effect on the shear crushing of materials, but is not conducive to the impact crushing of materials. Increasing the Angle of the first stage counterattack plate can increase the number of impact collisions and enhance the impact crushing effect, but is not conducive to the shear crushing of materials.The same is true for the second or third strike boards.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
