The screw discharge sedimentation centrifuge has a wide range of applications, large production capacity, compact structure, small floor space, and can be used for solid dewatering and liquid clarification. At present, the quality of products produced by domestic enterprises still fails to meet the demands of users, and the return rate is relatively high. Overall, the domestic supply of this product exceeds the demand, but large-sized, high-speed and fully automatic products still mainly rely on imports.
