The role and daily maintenance of shredder in garbage disposal

A shredder is a commonly used crushing equipment, mainly used for coarse or fine crushing of large materials. It is widely used in various fields such as waste recycling, scrap metal processing, waste paper recycling, and waste plastic processing. The shredder uses the mechanical principles of shearing, tearing, and crushing to cut materials into smaller pieces for subsequent processing or recycling. Its structure is diverse, including single axis, double axis, and four axis types, which can be selected according to material characteristics and processing requirements. The shredder has the advantages of uniform discharge, high shredding efficiency, large output, and reliable performance, and is an important equipment in garbage treatment and resource recycling.

In order to continuously meet the high quality, high efficiency, and high-end requirements of the shredder market, Zhongcheng Machinery has been updating and transforming its shredder series products year by year, constantly improving the quality of its products. Our series of shredders are exported to Southeast Asia, Europe, America and other regions. At present, our company's series of wood shredders use wear-resistant pads chrome plated on the cutterhead, and the flying knife, bottom knife, and flying knife bolts are made of special steel. The knife changing door of the large wood shredder is available in two types: oil cylinder push-pull and manual, which can be selected by users. Gathering new technologies and dedicating ourselves to new large-scale shredders, plastic shredders, wire rope shredders, wood shredders, etc. Not only do they have high output and low energy consumption, but they also produce high-quality blades with high cost-effectiveness.

A. The shredder plays a crucial role in garbage disposal, which is reflected in the following aspects:

1. Improve the efficiency of garbage disposal

The shredder is designed for efficient batch processing of various materials, whether it is tree branches, paper sheets, plastic sheets, or waste such as tires, metals, cables, etc., it can quickly shred them into fragments of specified sizes. This efficient processing capability greatly shortens the time for garbage disposal and improves overall processing efficiency.

2. Promote resource recycling and utilization

Through the processing of shredders, many previously difficult to recycle waste can be transformed into reusable resources. For example, after shredding plastics, paper, etc., they can be more easily reprocessed to produce new products. This not only helps reduce resource waste, but also promotes the development of circular economy.

3. Reduce environmental pollution

The shredder can effectively reduce the volume and weight of waste when processing it, thereby reducing the pressure on the environment. In addition, the shredder can also be equipped with environmental protection facilities such as dust removal and deodorization, further reducing the impact of the processing on the environment. This helps to reduce pollution caused by landfill and incineration, and protect the ecological environment.

4. Reduce transportation and landfill costs

The volume of shredded material is significantly reduced, making it easier to compress and store, saving a lot of space and transportation costs. At the same time, due to the reduction in volume, landfills can accommodate more garbage, reducing landfill costs.

5. Promote the development of the waste disposal industry

The application of shredders has promoted technological innovation and development in the waste disposal industry. In order to continuously improve the performance and processing efficiency of shredders, enterprises and research institutions need to increase their research and innovation efforts in shredder technology. This helps to enhance the technological level and competitiveness of the entire industry, and promote the healthy development of the industry.

In summary, shredders play a positive role in various aspects of garbage disposal, not only improving processing efficiency and promoting resource recycling, but also reducing environmental pollution, lowering transportation and landfill costs, and promoting the development of the waste disposal industry.

B. Precautions for daily use of shredder:

1. Before starting up, ensure that the host is stable and does not swing back and forth.

2. Before starting up, check if all connecting bolts are tightened. If there is any looseness, tighten the bolts before starting up.

Before starting up, the gearbox and bearings should be lubricated as required.

After turning on the power for the first time, observe the rotation direction of the two main shafts of the shredder and request that the main shaft of the shredder rotate inward towards the main machine. If there are errors, adjust the options and restart.

5. Start up for the first time, idle for 10-20 minutes, confirm that there is no abnormal noise or phenomenon, and operate normally before proceeding

6. The first trial feeding should be uniform and not too aggressive. If there are no problems during the trial run, the material can be evenly loaded and work normally.

7. During the work process, the head, hands, and other parts should not be placed near the feeding port to prevent splashing objects from injuring the body and endangering one's own life safety during the shredding process.

When repairing equipment, it is necessary to: power off and stop the machine, perform single person maintenance, disassemble and assemble the equipment according to the maintenance instructions (using special tools), and avoid rough operations such as knocking or smashing important parts of the shredder.

C. Factors affecting the performance of dual axis shredder:

We often use more than one type of shredder, which can be classified into different types based on their structure and composition. According to different cutting methods and tools, it can also be divided into single axis, double axis, four axis, etc. The commonly used equipment is a dual axis shredder. For double axis shredder equipment, many customers may encounter situations where the shredding effect is not ideal during use. So let's briefly introduce what factors affect the performance of a dual axis shredder in daily production processes?

1. Humidity of the material. If the humidity of the material is too high, it is easy for the material to clog in the crusher, resulting in a decrease in relative crushing capacity.

2. There is a problem with the material of the shredder hammer and jaw plate. If the material of the hammer head and jaw plate is poor, the hardness is not strong, and the wear resistance is not sufficient, it will seriously affect the shredding ability and fail to meet the expected requirements.

3. The hardness of the material. The harder the material, the harder it is to tear. Poor tearing effect and slow tearing speed.

4. Material composition. The tearing effect varies depending on the material composition and particle size. It is necessary to screen and separate particle sizes and crush them.

5. Fineness of shredded materials. The higher the fineness standard, the finer the tearing material and the stronger the tearing ability.

These are some common factors that affect the use of dual axis shredders. In fact, in actual use, in addition to the above factors, there are many other factors that can affect the effectiveness of the dual axis shredder, but many of them are caused by improper operation during use. Therefore, some precautions and operations of the double axis shredder also need to be paid more attention to.

The shredder has broad development prospects in the future. With the increasing awareness of environmental protection and the promotion of environmental policies, shredders will play a greater role in garbage disposal and resource recycling. Intelligent, efficient, energy-saving, and modular design will become important directions for the development of shredders. By integrating IoT, big data, and artificial intelligence technologies, the shredder will achieve remote monitoring, fault warning, and automatic adjustment of working modes, improving the stability and efficiency of equipment operation. At the same time, the application of new materials and processes will further enhance the durability and processing capacity of shredders, meeting more diverse processing needs. In the future, shredders will become an important force in promoting the development of the waste treatment and resource recycling industry.
