Dual shaft shredder

Product introduction

The dual shaft shredder, also known as the shear shredder, is a shredder that reduces the size of materials through cutting, tearing and squeezing. This dual shaft shredder is widely used in waste plastics, waste rubber, wood and other large-volume wastes, and provides reliable services for the early-stage crushing and volume reduction treatment of waste recycling.

Structure

1. The main body of the shredder: The main body of the equipment adopts high-quality steel plate welding to eliminate stress treatment/ overall machining to ensure the stability of the equipment under heavy load for a long time.

2. Movable knife/fixed knife: The movable knife material is made of special special alloy tool steel forging blanks, precision machining, multiple heat treatments and low temperature freezing heat treatment technology. The overall toughness and hardness are consistent and can be used repeatedly to ensure the cutting performance and Service life. The fixed knife adopts a patented hook-type installation to optimize the tool replacement function and make the tool maintenance and replacement more efficient.

3. Bearing/seal: The bearing seat adopts the patented split-and-disassemble type, which can quickly remove the movable knife, fixed knife, bearing and other parts, easy to maintain and replace the knife, and the unique sealing structure effectively prevents the contact of broken objects and grease. Liquid materials can also protect bearings and gears.

4. Cutter shaft: It is processed and refined with high-strength and heavy-duty special steel, which is more reasonable with the cutter to provide powerful power for cutting.

Performance characteristics

1. The dual shaft shredder can crush hard-to-powder bulk materials, baskets, pipes, plates, wood, tires, scrap metal barrels, and large rolls of film.

2. The combined structure of the extra-thick plate processing frame, the powerful rotating shaft of the large-angle hexagonal column, and the large-diameter sturdy input hopper, so you can safely input large-scale raw materials.

3. The unique rotary knife is designed and processed in terms of thickness, shape, arrangement order, etc., with strong shearing force, sharp blade, and capable of breaking.

4. The dual shaft shredder equipment runs at low speed, with low noise and less dust.

5. The knives are made of special alloy steel, strong and durable.

Equipment advantages

1. Heavy movable knife, high crushing power, all tools are made of alloy steel casting, strong and long service life.

2. The frame of the dual shaft shredder is thick, which can resist high torque and is very strong.

3. It adopts microcomputer (PC) automatic control, with start, stop, reverse and overload automatic reverse control functions.

4. The equipment has the characteristics of low speed, high torque, low noise, and dust can reach environmental protection standards.

5. Dual shaft shredder equipment is easy to adjust, low maintenance cost, economical and durable.

6. The thickness of the cutter and the number of claws can be changed according to different materials.

Pay attention to the points

1. Before starting the dual shaft shredder, check whether the machine is supporting the door. Do not open the door when the machine is running to prevent danger.

2. If the equipment is not started in the air, it will be in normal operation, which is only for production purposes.

3. The dual shaft shredder equipment is based on the particle size requirements of imported materials, and the conference equipment is damaged and the output is low.

4. The result is abnormally suspended, the inspection is stopped, the problem is solved and the production is put into production.

5. Lubricant is added regularly to rotate the bearing parts, and the thin wax of double shaft crusher is also called engine oil.

6. It is composed of lubricating oil and thickeners (calcium, sodium, aluminum, etc.). It has great adaptability to load and speed, but it has great friction loss and is not suitable for high speed.

Maintenance considerations

1. Periodic inspection during execution. If there is abnormal noise or the bearing temperature exceeds 70°C, stop the inspection immediately, eliminate the fault immediately, and then start operation.

2. It can be supplied only after the machine is running normally. The supply must be uniform to prevent hard iron from mixing. The supply must be stopped before the machine is shut down. After the machine stopped working, the material broke and the power supply was cut off.

3. After the discharge port is checked or adjusted, the rotor and other parts can be manually rotated to avoid friction and shaking, so that the motor can rotate flexibly before starting.

4. Be sure to check whether the enclosure sealing strip is clean and tidy. Bearing grease needs to be changed monthly, and it feels like it needs to be changed every 3 months.

5. When checking whether the fasteners are loose, mainly check the screws of the hammers on both sides of the rotor to prevent them from being pressed down. Both ends of the hammer exposed the rotor, hit the car body and damaged mechanical parts.

6. In order to ensure the safety of workers and equipment, maintenance, adjustment and cleaning are prohibited during the operation of the dual shaft shredder.

7. The size of the crushed product is too large. Please stop the mechanical inspection of the wear state of the blow bar to prevent the rotor from wearing.

8. If the hammer needs to be used repeatedly at 180 degrees due to wear, the weight of each hammer must be kept in balance to avoid vibration after the machine is started.
