Custom-made stainless steel boxes of various specifications, feeding height, conveying capacity, for irregular powders, crushed materials, granules, and flake materials, etc., to deliver the materials to the designated main machine hopper according to production needs. Screw feeder purpose: The screw conveyor feeder is an auxiliary machine required for plastic processing equipment, capable of directly and automatically conveying powdered or granular plastic raw materials to the hopper, or into containers such as high-speed mixers and blenders. The parts that come into contact with the raw materials are made of stainless steel, ensuring that the materials are not contaminated and no foreign objects are introduced during the conveying process, allowing for a fully enclosed and automated production process. The design is reasonable, and operation and maintenance are convenient. Compared to vacuum feeders, it eliminates the frequent need to clean filters. This machine has a wide range of applications, suitable for conveying powdered materials, plastic granules, powder-granule mixtures, and crushed materials. It can also be used for the conveying and feeding of powders and granules in pharmaceutical and chemical production processes. ZD400 Screw Feeder Main Technical Parameters: Motor power: 1.5kw 2.
