Profile

This series of products is a new type of product in the series of hammer crusher. Its named for the rotator which can bilateral rotation and without bar. The PCK Model Reversibility Hammer Crusher is one of the main equipment in metallurgical, building materials, chemical industry and hydroelectric industry which used for fine crushing the brittle materials with medium hardness, such as coking coal, small limestone, gypsum, alum, brick, tile and so on, the compressive strength of the broken material is not more than 150Mpa, and the surface moisture is not more than 15%.  

Technical Parameters

Feature

-The PCK Model Reversibility Hammer Crusher overcame the problem of blockage caused by the high humidity of the material.

-The PCK Model Reversibility Hammer Crusher improves the utilization of the hammer head, reduces the frequency of the replacement of the hammer, and ensures the uniformity of the grain size.

-The series of products have high output and low operating cost.

Working Principle

The material is broken along the first and second counter plate through a certain length of repeated impact in a set flow path, and the lower grate can determine the size of the material. Broken material in contact with board hammer, after that it was thrown to the strike back board to achieve partial breakage, it makes a part of the material gets crushed in the air. Although the flow direction of the material block looks chaotic; in fact, the center of gravity of the material block is constrained by the flow line of the counterattack plate, so that is a regular pattern.The working principle of the above crusher can be summed up in three aspects.

1.Free impact breakage

It is the leading part of the crushing effect. When the board hammer is contacted with the material, the material is broken and thrown at two times of the rotor speed, and most of the dust is produced by the impact of the material block on the space.

2.Strike back breakage

The breakage block group is shot along the mechanical trajectory and reflects from the counterattack plate,and the counterattack plate is the leading factor to control the material flow direction, and it also produces partial crushing effect.

3.Milling breakage

The material enters the broken section of the board hammer, and the bulk material is milling broken and thrown out high speed by hammer board. In addition, the materials through the above two kinds of breakage that have not been broken or larger than the size of the outlet, they are also broken by high speed rotating hammers board at the outlet.

Maintenance

1. The PCK Model Reversibility Hammer Crusher is used for crushing and selecting fine coal, and the requirement for the moisture of coal shall not exceed 14%.

2. The crusher belongs to the large vibration and shock equipment, the tightening of the anchor bolts and the shell bolts should be checked regularly, if the loosening should be fastened in time.

3. The hammerhead used for crushing is easy to abrasion, and should be checked and replaced regularly in the use, and the general use time is 3-----5 weeks.

4. After 2 weeks of continuous operation of the same machine, the reverse operation must be made to ensure the uniform wear of the hammerhead.

5. The motor rated current and voltage application within the specified range, when abnormal cut off the power supply, should shut down immediately.

6. Keep rotor bearing lubricated, and replenishment new molynoc grease timely.

7. Check the change of motor and rotor bearing working temperature in time (when the ambient temperature is 40 degrees), the rotor bearing temperature should not exceed 70 degrees, and the motor should not exceed 60 degrees.

8. Each indicator should keep normal work, the data to be indicated is accurate and reliable, and should be replaced in time when the problem is found.

9. After accidents or overhaul, the machine needs to be carefully checked

10. When the rotor is blocked, the power is cut off immediately. It is forbidden to start the motor by force. It is necessary to open the inspection, then remove the coal in the cavity, the rotor can be operated with the hand plate, and the motor can be started after it is flexible to use.

11. After the production is stopped, should be cleaning the PCK Model Reversibility Hammer Crusher. When cleaning the residual coal in the crusher, it is necessary to stop the rotor and strictly prohibit anyone to start the motor.

FAQ

1. What are the advantages of the PCK Model Reversibility Hammer Crusher?

   -The PCK Model Reversibility Hammer Crusher has two sets of cavity type, and the rotor can make positive and negative rotation to achieve crushing function. After hammers are used for a period of time, they do not need to disassemble and install. They can be directly reversed, so they are fast and convenient to operate.

2. Does the mainframe only need to open the box for maintenance?

-The PCK Model Reversibility Hammer Crusher adopts the hydraulic opening device, the box can be opened to the maximum and easy to maintain.

3. What is the minimum discharge size of the PCK Model Reversibility Hammer Crusher?

    -The PCK Model Reversibility Hammer Crusher is mainly fine-grained, and the conventional grain size is 3~6mm.
