What is the internal structure of the shredder equipment?

What is the internal structure of the shredder equipment?

2024.11.12

The shredder equipment is a kind of machinery commonly used for material crushing and recycling. Its internal structure and performance characteristics are crucial to the operating efficiency and crushing effect of the equipment. The following is a detailed analysis of the internal structure and performance of the shredder equipment:

Frame assembly

The frame assembly of the shredder is the supporting frame of the entire equipment, carrying other components. It usually includes the base, columns, beams and other parts, and is made of high-strength materials to ensure the stability and durability of the equipment.

Under the frame, a lower hopper is designed to collect and process the crushed materials.

Transmission mechanism

The transmission mechanism is the power core of the shredder, responsible for transmitting the rotational power of the motor to the cutting blade or drum.

It is mainly composed of a motor, a small pulley, a V-belt, a large pulley, a reducer and a coupling. The motor drives the reducer through the belt and pulley. The reducer reduces the speed of the motor and transmits it to the main shaft. The main shaft then drives the cutting blade or roller to rotate through the coupling.

Chassis assembly

The chassis assembly is the main part of the shredder, which contains key components such as the cutting blade, roller, and bearing.

The chassis is usually composed of upper and lower panels, upper and lower side panels, and bearing boxes. These components are connected together by welding or bolts to form a closed space. In this space, the cutting blade or roller rotates at high speed to cut and crush the material.

Moving knife group and fixed knife group

The moving knife group and fixed knife group are one of the key components of the shredder and are directly involved in the cutting and crushing process of the material.

The moving knife group is usually composed of the main shaft, coupling, cover, bearing, locking nut, lock plate, spacer, moving knife, etc. The moving knife is installed on the main shaft through the bearing and is driven to rotate by the motor and transmission mechanism.

The fixed blade group is installed inside the chassis, forming a certain angle with the moving blade. When the material enters, the moving blade and the fixed blade cooperate with each other to cut and crush the material.

Feed hopper and discharge port

The feed hopper is the entrance part of the shredder, responsible for feeding the material to be processed into the equipment. The design of the feed hopper will vary according to the type and size of the material being processed to ensure that the material can enter the shredder smoothly.

The discharge port is located below or on the side of the shredder, used to discharge the crushed material out of the equipment. The design of the discharge port will also be adjusted according to actual needs to meet the discharge requirements of materials of different specifications and shapes.

The shredder equipment has the performance characteristics of strong crushing capacity, high efficiency, easy maintenance and replacement of blades, high degree of automation and strong adaptability. These characteristics make the shredder have a wide range of application prospects in the field of material crushing and recycling.

How to maintain scrap metal shredder equipment ?

How to maintain scrap metal shredder equipment
?

2024.10.16

The maintenance of scrap metal shredder equipment is the key to ensure its normal operation and extend its service life. The following are some specific maintenance measures:

1. Daily maintenance

Cleaning work: After work every day, the shredder should be cleaned to remove residual metal fragments, dust, etc. Pay special attention to cleaning the feed inlet, discharge port and blade parts to prevent blockage and increased wear. When cleaning, the machine should be turned off and the power supply should be unplugged to ensure safety.

Check fasteners: Check whether the fasteners of the shredder, such as bolts and nuts, are loose or damaged. If loose or damaged, they should be tightened or replaced in time to prevent equipment failure during operation.

Check lubrication: The bearings, gears and other parts of the shredder need to be regularly added or replaced with lubricating oil to reduce wear and friction. Lubricate in time according to the use of the equipment and the consumption of lubricating oil.

Check the electrical system: Regularly check whether the electrical system components such as wires, cables, switches, and motors are normal. If any abnormality is found, the fault should be eliminated in time to avoid damage to the equipment by the electrical system.

2. Regular maintenance

Blade replacement: The blade is the core component of the shredder, and its sharpness directly affects the crushing effect of the equipment. Replace the blade in time according to the use of the equipment and the wear of the blade. When replacing, the specifications and models that match the original blade should be selected.

Bearing inspection and replacement: Bearings are important components of the shredder, and their life directly affects the stability and service life of the equipment. Regularly check the wear of the bearings. If they are severely worn or damaged, they should be replaced in time. When replacing, ensure that the bearings are clean and lubricated.

Gear inspection: Gears are an important part of the shredder transmission system, and their operating conditions directly affect the crushing effect of the equipment. Regularly check the wear of the gears. If they are severely worn or damaged, they should be replaced or repaired in time.

Motor maintenance: The motor is the power source of the shredder, and its operating status directly affects the performance and service life of the equipment. Regularly check the operating status of the motor, including the temperature, vibration, noise, etc. of the motor. If any abnormality is found, the fault should be eliminated in time.

III. Idle maintenance

When the metal shredder equipment is in an idle state, maintenance work should also be done. Specific measures include dust prevention, rust prevention, moisture prevention, etc., to avoid problems such as internal rust and moisture in the machine parts, which will cause the machine to be paralyzed when it is used again.

IV. Precautions

Comply with operating procedures: Before maintenance, you should carefully read the equipment's instruction manual and operating procedures to ensure that maintenance is carried out in accordance with the prescribed steps and methods.

Use genuine accessories: When replacing parts, genuine accessories should be used to avoid using inferior or substitute parts to avoid affecting the performance and life of the equipment.

Maintenance records: Establish equipment maintenance records to record the equipment's maintenance time, maintenance content, replacement parts and other information for subsequent inquiries and references.

The maintenance of scrap metal shredder equipment involves many aspects, including daily maintenance, regular maintenance, idle maintenance and precautions. Only by doing these things well can we ensure the normal operation of the equipment and extend its service life.

Performance of plastic shredder equipment

Performance of plastic shredder equipment

2024.8.18

The performance of plastic shredder equipment is mainly reflected in the following aspects:

1. Processing capacity

Processing capacity: refers to the amount of waste processed per hour, usually in kilograms. Different models of plastic shredders have different processing capacities. For example, some models of equipment can process up to 300-1000kg/h, or even higher.

Feed particle size: Plastic shredders have certain requirements for feed particle size. Generally, materials less than 200mm can be directly fed into the shredder for processing.

2. Work efficiency and energy consumption

Work efficiency: The plastic shredder is driven by a high-speed, high-torque motor. The hammers on the main rotor take turns to hit the material to be crushed in the cavity, and the material is torn into uniformly sized fragments by shearing, extrusion, etc., with high work efficiency.

Energy consumption: Although the plastic shredder consumes a certain amount of electricity when working, due to its reasonable design and optimized structure, the overall energy consumption is relatively low, and it is a high-performance and low-power device.
