Fine crusher, also known as high-efficiency fine crusher, third-generation fine crusher, etc. This machine has a wide range of uses, especially suitable for making abrasives, refractory materials, cement, quartz sand, steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate and other hard and brittle materials. It is a high-efficiency, energy-saving gravel and sand making equipment with fine and medium crushing, which saves 50% energy than the traditional fine crusher.

It is very troublesome when problems arise with such efficient equipment. Among other things, if there is a problem with wear of the fine crusher shaft, just contact Henan Global Heavy Industry. The excellent bonding and anti-wear properties of carbon nanopolymer materials are used to increase the surface bonding area and bonding force of the material through surface baking, polishing and other treatments to ensure that the material will not fall off. Not only that, this material and targeted repair process can realize online repair of coal crusher shaft wear, and the repair process is not limited by the amount of unilateral wear of the shaft. The specific repair steps for fine crusher shaft wear are as follows:

(1) Disassemble other parts to expose the worn parts;

(2) Check the repair surface to determine the amount of wear;

(3) Use oxygen acetylene for surface baking oil treatment.

(4) Use an angle grinder to roughen the surface of the shaft head;

(5) Dry test the tooling. After confirming that the size of the tooling is correct, apply release agent on the inner surface of the tooling and let it dry for later use;

(6) Mix carbon nanopolymer materials in proportion;

(7) Apply the material to the repair surface and install the tooling;

(8) Wait for the material to solidify;

(9) After the material solidifies, disassemble the tooling;

(10) Verify the dimensions after repair and remove excess material;

(11) Reinstall the parts and repair is completed.
