Two shaft shredder (also known as biaxial crusher, shear shredder), two shaft shredder are mainly used in waste plastics, waste rubber, wood, paint barrels, waste appliances shell (plastic shell, metal shell), waste Circuit boards (circuit boards), scrap cables and other large volume of waste, compared to other grinder equipment, biaxial shredders are slow high torque crushing equipment, two shaft shredder in the processing of materials mainly concentrated in the metal , The crushing of plastic parts and the crushing of large hard materials, our company Two shaft shredder is a kind of material crushing and processing equipment which is suitable for the domestic market after absorbing foreign advanced experience according to the specific development needs of the market. For the recycling of waste in China pre-crushing, reducing capacity to provide quality and reliable equipment.

Two shaft shredder structure principle

Two shaft shredder As the name suggests, two sets of rotors equipped with a shredder blade are relatively rotated in the machine chamber to squeeze the material entering the chamber with the principle of the angle between the two shafts. Due to the special design of the blade, After the angle of the material is fixed by the edges and corners of the blade to further create the conditions for the contraction of the angle, the material strength to reach the material yield strength after the material began to break between the blades to complete the tear effect.
Two shaft shredder Structural features:
1. Crusher body
The main body of the equipment is made of high quality steel plate welding to eliminate the stress treatment and the whole machining to ensure the stability of the equipment in the heavy load.
2. Knife / Knife
The tool is made of special special alloy tool steel forging blank, precision machining, multiple heat treatment and low temperature refrigeration heat treatment technology, the overall toughness of the same hardness can be used repeatedly to ensure that the cutting performance and service life. Set the knife with a patented hook-type installation, optimize the tool replacement function, so that tool maintenance replacement more efficient.
3. Bearing / seal
It is easy to maintain and replace the tool. The unique sealing structure effectively blocks the contact between the broken material and the grease, and the liquid material can also protect the bearing. The bearing can be used to protect the bearing. And gears.
4. Knife axis
The use of high-strength heavy-duty special steel processing and refining, more reasonable with the tool for cutting to provide a strong power.
