What kind of materials can the double shaft shredder shred?

Double shaft shredder manufacturing workshop

With the development of society, the double-shaft shredder is used by more and more enterprises. With its own advantages, the double-shaft shredder also plays a very important role in material handling. Under the action of the double-shaft shredder, various materials can be processed, and waste cars, waste tires, waste metals, etc. can be shredded, which greatly saves resources and energy.

shredder material

The double-shaft shredder has a good shredding effect, high output, and no noise. It is an ideal equipment for coarse shredding of various scrap iron and steel, scrap aluminum and aluminum alloys, oil drum color steel tiles, cans, and waste household appliances. The equipment has the characteristics of saving transportation costs, saving landfill costs, and recycling and reusing waste after crushing.

The double-shaft shredder is different from the metal shredder equipment. The metal shredder adopts hammer-type impact crushing, while the double-shaft shredder uses double guide rollers to roll and shear in opposite directions. It is mainly used to crush various metals, reducing its volume and saving space. In order to facilitate transportation and recycling, such as scrap iron and aluminum, waste furniture, waste cars and motorcycles, electronic waste, etc.

Double-shaft shredders can generally be used to shred hard-to-break aluminum alloys, broken bridge aluminum, rubber tires, car shells, large pipes, wood, electrical components, cables, PET bottles, cardboard, circuit boards, wood, and oil drums , cans and other materials, these materials are bulky, and the processing efficiency of traditional equipment is low, but the coarse crushing effect of materials can be easily achieved through the dual-shaft shredder, which is convenient for subsequent processing of materials.

The working conditions of the cutter of the double-shaft shredder are extremely harsh, and the working intensity is high. Therefore, the surface of the cutter often has peeling, chipping, wear, etc. during the working process. Therefore, manufacturers of the double-shaft shredder require the surface of the cutter to have a high resistance Abrasiveness, but also requires high toughness to adapt to harsh working conditions.

How To Maintain And Maintain The Main Shaft Bearing Of Double Shaft Shredder Equipment?

Double Shaft Shredder 
The dual-shaft shredder has high working intensity and harsh operating environment. The main shaft of the equipment, the blade of the shredder, and the bearing of the main shaft are all faced with high-load operations. The maintenance work of the shredder bearing is introduced today.


Why should the bearing be regularly maintained?

1. Bearing maintenance has the effect of cooling and heat dissipation.


Prevent the shredder spindle from increasing the temperature of the parts due to frictional heat generation, resulting in aggravated adhesive wear and corrosion wear, reducing work efficiency and causing damage to the spindle.


2. Sealing protection.


The lubricating grease of the bearing can effectively isolate the moisture, oxygen and harmful medium erosion in the humid air, and can also prevent water, dust and impurities from invading friction.


3. Effectively reduce friction and wear.


Since the bearing lubricating film can reduce the friction factor between the two moving parts, it will reduce the wear consumption of the parts, thereby prolonging the life of the dual-shaft shredder, reducing power consumption and improving the operating characteristics of the equipment.

1. Clean the floating coal and sundries around the bearing chamber of the main shaft every shift every day. When cleaning the bearings, the site should be cleaned to ensure a clean environment and prevent secondary pollution of the bearings.


2. Check the heating and wear of the bearing from time to time, determine whether the bearing is in good condition and whether it is worn, regularly add lubricating grease, and replace the oil seal;


3. If the bearing has abnormal noise or heat due to wear, it is necessary to replace the bearing, clean the bearing chamber, replace the new bearing, add lubricating grease, replace the oil seal, and then assemble, restore and install.


Installation steps of the main shaft bearing of the dual-shaft shredder


1. Before installing the bearing, the bearing chamber and inner oil should be sealed on the main shaft;


2. Before installing the bearing, check whether the bearing is rusted and whether the rotation is flexible. If there is, clean it with diesel oil or kerosene;


3. Before installing the bearing, the bearing oil bath should be heated, and the bearing should be heated and then installed on the shaft. During the installation process, the end face of the bearing should not be directly hit with tools such as a hammer to avoid damage to the bearing;


4. After the bearing is installed, put the bearing on the main shaft, and seal the transparent cover and outer oil after installation.


5. After the bearing is installed, the double-shaft shredder is started, and it should run idly for 30 minutes to check the operation of the equipment.
