Classification and daily maintenance manual for plastic crushers

Plastic crushers are essential machines used to break down waste plastics and factory plastic scraps. These devices play a crucial role in the recycling industry, helping to process various types of plastic materials efficiently. The motor power of a typical plastic crusher ranges from 3.5 kW to 150 kW, while the knife roll speed can vary between 150 and 500 revolutions per minute (RPM). The machine is designed with either a tangential or top feed system, and the knife roll typically consists of a solid cutting roll paired with a hollow guide roll for optimal performance. The operation of a plastic crusher involves the motor driving the movable cutter head at high speed. As it rotates, the moving knife interacts with the fixed knife, creating a gap that allows for effective crushing and cutting of the plastic material. Large plastic blocks are broken down into smaller pieces, which are then filtered through a screen before being discharged as output. Plastic crushers come in different types based on their design and application: **1. Hard Plastic Crusher** - Ideal for processing rigid materials such as ABS, PE, and PP boards. - Features a rectangular feeding port specifically designed for sheet materials, enhancing efficiency when handling long strips. - Optional suction fans and storage tanks can be integrated to create a complete recycling system. - Equipped with sealed bearings for long-lasting performance, and the knife design ensures even granulation and a neat appearance. **2. Strong Plastic Crusher** - Combines claw knives and flat knives for versatile use in processing sheets, pipes, profiles, and packaging materials. - Designed with sealed bearings for durability, and uses alloy steel blades for consistent particle size. - Knife seats undergo heat-shrink treatment and are balanced to ensure smooth operation and an attractive design. **3. Pipe Plastic Crusher** - Specialized for crushing small to medium-sized plastic pipes, including PE, PVC, and silicon core pipes. - Features a circular feeding port for efficient handling of long pipe materials. - Can be combined with suction fans and storage tanks to optimize the recycling process. **Maintenance Tips for Plastic Crushers** 1. Place the machine in a well-ventilated area to ensure proper cooling of the motor and extend its lifespan. 2. Regularly lubricate the bearings to maintain smooth rotation. 3. After the first hour of operation, check and tighten the screws securing the moving and fixed knives. 4. Inspect the cutting tools frequently to ensure sharpness and prevent damage to other components. 5. Adjust the gap between the moving and fixed knives: 0.8 mm for machines with 20 HP or more, and 0.5 mm for lower horsepower models. 6. Before restarting the machine, remove any leftover material to reduce startup resistance. Periodically clean the inertia cover and pulley cover to remove dust buildup. 7. Ensure the machine is properly grounded for safety. 8. Check the belt tension regularly and adjust if necessary. This content is provided by Foshan Wenfeng Plastic Machinery Co., Ltd.

Solar Light

Solar street lights have several advantages over traditional street lights. Here are some of the benefits of solar street lights:

Energy-efficient: Solar street lights are powered by renewable energy from the sun, making them highly energy-efficient and eco-friendly. They do not require electricity from the grid, which reduces electricity bills and carbon emissions.
Although the initial cost of installing solar street lights may be higher than traditional street lights, they are more cost-effective in the long run. They require minimal maintenance and have a longer lifespan, reducing replacement and repair costs.
Solar street lights are easy to install and can be installed in remote areas without access to electricity. They do not require any wiring or trenching, which makes the installation process quick and hassle-free.
Solar street lights provide better visibility on roads and sidewalks, making them safer for pedestrians and drivers. They also reduce the risk of accidents and crime in poorly lit areas.
Solar street lights are equipped with batteries that store energy during the day and provide power at night. They are designed to work even in cloudy weather and can provide illumination for several nights without sunlight.
