The factory absorbed advanced foreign technology and developed series high-speed eddy-durrent multipurpose poweder mill. The machine is an equipment of grinding microfine powder in plastic, mine, chemical, metallurgical and other industries, especially is used in grinding retrieved plastic grain of thermoplastics PVC, PE. The practice and experience of plastic product factories shows that the chemical and physics functions of the products can keep all parameters of new raw material if adding 20-30% retrieved plastic powder So it is the best equipment for reducing cost, saving expense and solve waste plastic.
