The new way of using our screw feeder
Screw feeders are used all over the world in a variety of industries to transport a variety of powdered raw materials and other materials. For example, screw feeders play an important role in the material recycling method that many companies in Japan have recently adopted. You can probably imagine what the term material recycling means, but do you know what it means?
What is material recycling?
Material recycling is the process of reusing discarded materials and regenerating them as raw materials for new products. This method helps prevent resource waste and reduces environmental impact.
Examples
・Plastic: Collect PET bottles, grind and melt them, and regenerate them into new plastic products.
・Metal: Melt aluminum cans and regenerate them into new aluminum products.
・Paper: Turn old paper back into pulp and regenerate it into new paper products.
Role of Screw Feeder
Screw feeders play a crucial role in the recycling process by efficiently moving and supplying materials. Specifically, they serve the following functions:
・Uniform Material Supply: Screw feeders can supply materials uniformly to the recycling line. This ensures that processing equipment operates steadily, enabling efficient recycling.
・Controlled Supply Rate: Screw feeders can adjust the supply rate, optimizing the load on processing equipment. This prevents clogs and overloads, ensuring stable operation.
・Pre-Grinding and Pre-Mixing: Recycled materials are often fed through screw feeders before being ground or mixed. The even distribution by the screw feeder ensures efficient subsequent processing.
Specific Examples of Use
Plastic Recycling: When recycling waste plastic, screw feeders supply material to grinders. By feeding the material uniformly, grinders operate more efficiently, producing uniformly sized recycled plastic.
・Food Waste Recycling: In recycling food waste, screw feeders supply waste to bioreactors. In bioreactors, organic matter is decomposed to produce biogas or fertilizer. The even supply maintained by the screw feeder ensures smooth progression of the decomposition process.
・Metal Recycling: In metal scrap recycling, screw feeders supply material to crushers or smelters. Particularly when handling fine metal particles or powdery scrap, uniform supply by the screw feeder improves the efficiency and safety of processing equipment.
Screw feeders are essential devices in material recycling processes, supporting efficient recycling by achieving uniform and controlled material supply. It is important to select appropriate screw feeders based on the installation environment and material characteristics, ensuring proper design and adjustment according to specific needs.
