HXJQ PCZ heavy-duty hammer crusher

HXJQ PCZ heavy-duty hammer crusher

With the features of high efficiency and energy saving, PCZ heavy-duty hammer crusher adopts the mature technologies, which can achieve once-molding crushing effect. It combines the advantages of jaw crusher, hammer crusher and impact crusher, and becomes one of the most popular hammer crushing machines.

PCZ heavy hammer crusher applications

After optimization and redesign, PCZ heavy hammer crusher becomes the new crushing machine which can crush large and small materials simultaneously.

Wide range of PCZ hammer crusher

Wide range of PCZ hammer crusher

It mainly applied in the industries of mines, metallurgy, building materials, road construction, railway building, water conservancy, cement, sand, coal, chemical engineering, electricity, and compound fertilizer.

Heavy-duty hammer crusher can be used in the dry crushing process and wet crushing process. During the wet crushing process, materials can be mixed with water to continue crushing operation, and the water content is required to be no more than 15%.

Heavy-duty hammer crusher is usually used to crush the ores of compressive strength no more than 200MPa, or calcium content no less than 40%, such as limestone, coal, salt, gypsum, bricks, tiles, gangue, etc.

Various advantages of heavy-duty hammer crusher

The feed size is large and the output is high

The feeding size of the heavy hammer crusher can reach 750 mm, and the output of single hammer crusher can reach 3000 tons.

The design of the crushing cavity conforms to the dynamic principle. The unique structure without sieve plate increases the throughput of the material, which can crush the wet material and solve the traditional hammer problem of easy to block and low output.

Low energy consumption and investment

The PCZ type heavy hammer crusher has a large feeding size, small discharge particle size, and a once-molding system, which completely realizes a low-cost operation.

Environmental protection and less pollution

It can crush the wet material, that is, when the wet material is crushed, water can be added to reduce dust pollution and protect workers' health and environment.

Excellent finished grain size

The material can be adjusted according to the demand which can meet various specifications.

Advanced parts and wear resistance

The PCZ type heavy hammer crusher produced by our company adopts the most sophisticated fittings, especially the selection of wear-resistant parts, and the hammer head is the most advanced technology and the most wear-resistant metal in China. 

working principle

The main working part of the PCZ type heavy hammer crusher is a rotor with a hammer (also called a hammerhead). The rotor consists of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feeding port, and crushed by the hammer.

In the lower part of the rotor, a sieve plate is arranged, and the size of the crushed material smaller than the mesh size is discharged through the sieve plate, and the material larger than the mesh size is remained on the sieve plate and continues to be struck and ground by the hammer, and discharged through the sieve plate.

Frequently Asked Questions
  • Why the output size is too large?

    Show

    Reason: It may be that the hammerhead is worn too much, resulting in insufficient crushing force; it may also be that the screen strip is broken, and materials that do not meet the specifications are discharged.

    Solution: Stop immediately and check the degree of wear of the hammer. If the hammer is worn seriously, replace the hammer in time; check whether the sieve is broken or damaged. If there is any above, replace the sieve immediately.

  • When the hammer is broken, there is an abnormal knocking sound inside the body?

    Show

    Reason: Non-crushed material enters the inside of the machine (heavy hammer can only break the material type with compressive strength below 200 MPA. If the material is too hard, it will not break normally, or even damage the hammer); the liner fastener is relaxed, making The hammer hits the liner; the hammer or other part breaks.

    Solution: Stop the machine and check the chamber for unbreakable materials, or directly clean the crushing chamber; check the fastening of the liner and the gap between the hammer and the screen; replace the broken parts.

  • Why does the body produce abnormal vibration?

    Show

    Reason: When the hammer is replaced, the static balance of the rotor can't meet the standard; the hammer is broken, the rotor is out of balance; the pin is bent and broken; the disc will be cracked; the anchor bolt is loose.

    Solution: remove the hammerhead and select the hammerhead according to the weight, so that the total weight of the hammer on each hammer shaft is equal to the total weight of the hammer on the hammer shaft, that is, the static balance meets the requirements; replace the hammerhead; replace the pin shaft; Repair or replace the triangular disc or disc; tighten the anchor bolts.
