• Safety protection in the production of metal shredding

  Sep 30, 2024

  Metal shredders are highly efficient equipment that are popular in the metal recycling and processing industry. However, there are significant safety risks associated with shredding steel waste. How can we eliminate the occurrence of safety problems? The safety protection of metal shredders primarily focuses on preventing metal fragments from flying out during the crushing process. We cannot simply rely on baffles. Firstly, we should place the shredder a safe distance away from people. Then surround the production line of the metal shredding with a fence. And adjust the height of the fence according to the actual working situation. Furthermore, thicken the fence where flying debris is likely to be a greater concern. Add protective iron sheets to the shelters set up for the operators in the construction environment. Set up an approximately 10cm iron plate fence opposite the material transportation holes. The height of the fence should be able to prevent fragments from flying over. When our aclshredder is used for steel shredding, we must consider all possible scenarios and implement protective measures accordingly. As a shredder manufacturer, ensuring the safety of the equipment and providing comprehensive safety guidance during on-site installation is essential to effectively addressing the problem of safety protection.

• Operating a single or double shaft shredder precautions

  Jan 13, 2024

  What should we know when operating a shredding machine? 1. Regularly inspect all connecting bolts and the square head bolts for fixing the toothed plate. Prevents loosening and ensures the shredder's safety. 2. Lubricate each bearing bush, large and small gears, and special-shaped gears 1 to 2 times per shift to ensure sufficient lubricating oil inside the bearing bush and reduce over-decomposition wear on the bearing bush and gears. 3. Control the feeding particle size to ensure it does not exceed the specified size. Your ability to maintain continuous and uniform feeding is key to preventing material blockage and ensuring the efficient operation of the shredder. 4. Regularly check the temperature of the bearing. The temperature rise of the bearing bush should not exceed 25 to 30 degrees Celsius above room temperature. 5. Clean the bearing slide way of the moving roller frequently to remove dust and impurities to prevent materials from entering the moving roller and causing accidents due to its inability to move. 6. When there is a sudden power outage, first disconnect the power supply of the motor to prevent accidents caused by sudden power restoration. Then remove the unshredded materials from the shredder to prevent the safety pin from being cut off due to excessive load when the shredder starts. 7. Pay close attention to the working condition of the safety pin. If the safety pin is cut off, immediately disconnect the power supply to prevent the large pulley from rotating idly in the sleeve for an extended period. This idle rotation may cause excessive wear on its mating surface and even lead to shaft seizing and other accidents, resulting in significant damage to the equipment and downtime. 8. Operators must strictly follow the safety technical operation procedures and should not operate at will to prevent personal and equipment accidents.

• How to solve the problem of the shredder getting stuck?

  Oct 10, 2023

  While the aclshredder is versatile and can handle a variety of materials, such as plastic, tires, steel, and all kinds of waste, it's essential to remember that not all materials are suitable for shredding. Thick metal blocks, extremely tough materials, or materials that exceed the size limit for shredding should not be forced through the shredder. Doing so can cause the shredder to get stuck and, in severe cases, lead to damage. This caution is necessary to ensure responsible and safe operation.   Here, how can we avoid the phenomenon of material jamming in the twin shaft shredder?   Understanding the application fields of different types of shredders and the intricacies of shredding design is crucial. This knowledge empowers us to follow three key requirements and operate the two-shaft shredder effectively. 1.It is not allowed to exceed the hardness limit of the materials to be shredded by the double shaft shredder. 2. It is not allowed to exceed the design of the two shaft shredder for shredding materials. 3. Operate the aclshredder strictly in accordance with the rules. For some uncertain and questionable materials, we should conduct a trial run of the shredder in advance to prevent material jamming.

Before commencing work, it is necessary to inspect the double shaft metal shredder. Only after confirming that there are no errors can the machine be started. Before starting the machine, it is essential to run it for two minutes to preheat. Then, carry out the feeding. When shredding materials, we recommend selecting the same type of materials and ensuring uniform feeding to achieve optimal results. Do not feed too much material at once; otherwise, it may cause the machine to jam. When shutting down, we must wait until no materials are left before turning off the equipment. Then comes maintenance and lubrication. Effective maintenance of the shredder can significantly enhance its production efficiency and increase output. At the same time, understanding the characteristics of different products empowers us to make informed choices when selecting materials for blades. If the material we are shredding is of ordinary hardness, we can choose a blade made of a less expensive material to achieve a higher cost-performance. If the material we are shredding is of high hardness or difficult to shred, we should choose a blade that is relatively more flexible, better, and more durable.
