Two shaft shredder

The double-shaft shredder is an efficient equipment for crushing and reducing bulk materials. The following is a detailed introduction:

 Working principle

The double-shaft shredder shears, squeezes and tears the materials through two relatively rotating shafts with blades, so that the materials are torn into smaller pieces.

Structural composition

1. Motor: Provides power to drive the knife shaft to rotate. Electric motor or hydraulic motor can be used.

2. Reducer: Connects the motor and the knife shaft to reduce the high speed of the motor to the low speed of the knife shaft, so that the knife shaft obtains high torque.

3. Knife shaft: It is equipped with a crushing knife, which is a component that directly crushes the material. It is made of high-strength and heavy-duty special steel.

4. Crushing knife: It is divided into a moving knife and a fixed knife. The moving knife is installed on the knife shaft and rotates with the knife shaft, and the fixed knife is fixed on the frame. The knife is often made of special alloy steel with high hardness, high wear resistance and strong shear force.

5. Knife box: It contains the knife shaft and the crushing knife, and plays a protective role in the crushing process. It is usually made of thick plate with precision processing.

6. Electronic control system**: It adopts programmable logic controller (PLC) control to realize the start, stop, reversal and overload automatic reversal of the equipment.

Advantages and characteristics

1. Strong processing capacity**: It can handle a large amount of materials, such as wood, plastic, metal, tires and other solid wastes, with a throughput ranging from 300kg/h to 20t/h, suitable for handling difficult-to-crush materials in all walks of life.

2. Good crushing effect**: It can tear the material into smaller pieces to achieve the purpose of volume reduction, which is convenient for subsequent transportation, storage and reuse. For example, it can process large metal oil drums into small-sized pieces.

3. Wide application range**: It is widely used in urban waste treatment, agricultural waste treatment, industrial waste treatment, construction waste treatment and other fields. It can also be used to treat special wastes such as home appliance casings, electronic waste, and medical waste.

4.Environmental protection and energy saving**: effectively reduce the volume of waste, reduce the pressure of landfills, and the shredded materials are easier to classify, recycle and reuse; at the same time, the knife shaft has low speed, low noise, low energy consumption, and dust can meet environmental protection standards.

5.Easy operation and maintenance**: high degree of automation, can reduce manual operation and labor intensity; simple structure, bearing seat adopts split type design, easy to disassemble and replace knives, daily maintenance work is easy and simple, and the operating cost is low.

6.High safety**: the equipment is equipped with automatic reversing system, overload protection device and safety protection device, etc. For example, the machine is equipped with maximum safety current. When the motor is overloaded or the material is blocked, the knife shaft will automatically reverse to protect the machine, prevent equipment damage and personal injury.

 Application field

1. Environmental protection industry**: handle urban domestic waste, industrial waste, medical waste, etc., realize garbage volume reduction and resource recycling, reduce pollution to the environment, and promote harmless, reduced and resource-based garbage treatment.

2. Resource recycling industry**: used to shred scrap metal, plastic, wood, paper, etc., to facilitate subsequent sorting, smelting, regeneration and other treatments, improve resource recycling rate, and reduce resource waste.

3. Agricultural field**: can process agricultural waste such as straw and branches, convert them into biomass energy or organic fertilizer, realize the resource utilization of agricultural waste, and promote the sustainable development of agriculture.

-4. Construction industry**: crush waste building materials such as wood, bricks, concrete, etc., reduce the stacking and transportation costs of construction waste, and some materials can be reused for road base, backfill, etc.
