Mobile Stone Crushing Equipment Vertical Impact Crusher For Coal Rock Fly Ash

Vertical Impact Crusher Machine for Coal Fly Ash Crushing Brief Introduction:

Vertical Impact Crusher Machine consists of an encased rotor carrying swing hammers, whizzer classfier for fineness regulation and blower fan mounted on a solid shaft. Raw material to be pulverised enters the crushing chamber through the hopper and automatic rotary feeder. The impact of the hammer on the feed material against the liner plates reduces it into fine powder. The ground material is carried towards the whizzer classifier for classification and the over size particles are rejected by the classifier and returns to the crushing chamber for further grinding. The classified material is then conveyed into the cyclone for collection and bagging. A dust collector is provided in the system for ensuring dust free operation and no loss of ground powder.

Impact Crusher Specifications:

Portable Impact Stone Crusher Advantages:

◆ The impact crusher is more effective in handling materials with large moisture content, effectively preventing material blockage
◆ The impact crusher is suitable for a wider range of stone materials
◆ It has a wide adjustment range, can easily and flexibly adjust the discharge granularity
◆ Low wear rate of wear parts and high metal utilization rate
◆ The replacement of the spare parts of the impact crusher is simple and the maintenance cost is reduced accordingly

Vertical Impact Crusher Machine Working Theory:

Stone impact crusher is a crushing machine that uses impact energy to break up materials. When the machine is working, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of the hammer, it collides with the hammer on the rotor, and then is thrown to the counter-attack device to break again, and then rebounds from the counter-attack. Returning to the hammer action zone, the process is repeated, and the process is repeated. The material is repeatedly broken into the first, second and third counter-attack chambers until the material is crushed to the required particle size and discharged from the discharge port.

The stone material falls directly from the upper part of the machine into the high-speed rotating turntable; under the action of high-speed centrifugal force, the flying stone that is shunted around the turntable in another part of the turntable produces high-speed collision and high-density crushing. After the stone hits each other, a vortex motion is formed between the turntable and the casing to cause multiple blows and smashes.

Portable Vertical Impact Crushing Equipment Troubleshootings:

A. Impact crusher's bearing temperature is too high:
(1) First check if the grease is reduced
(2) Standardly, the grease should be filled with 50% of the housing volume
(3) It is necessary to clean the bearings and replace the grease in time
(4) If the wear is serious, please replace the bearing
B: Very strong knocking sound is generated inside the crushing chamber during operation:
(1) Stone crusher should be turned off immediately, clean the crush chamber and check if there is any material that cannot be broken into the crushing chamber
(2) The machine will generate huge vibration during operation, check the fastening of the lining and the gap between the hammer and the lining; whether the wear lining is detached or not
(3) Replace broken parts
C: Excessive particle size
(1) Should adjust the front and rear counter-rack clearance or replace the worn liner and plate hammer
(2) In addition, adjust the position of the counterattack so that the two sides and the frame lining can reach a relative gap to ensure the discharge granularity.
