Brief description The equipment has the characteristics of low speed, high conveying efficiency, step-less speed regulation, low energy consumption and so on. It can ensure that the material is conveyed to paste pump at a certain pressure. Application This equipment is based on a bi-axial spiral rectangular structure and is widely used in the treatment of paste materials such as slime, sludge, calcium carbide sludge, printing and dyeing sludge, etc. It is a part of the paste material pumping system. After stirring and conveying, the materials are conveyed to the KOS series paste pump through the bottom discharge port under the stirring of the twin-shaft coupled spiral blades. Effectively solve the problems of material compaction and uneven mixing. It greatly improves the transfer efficiency of paste and viscous materials, and reduces the unit time cost.
