Many customers consult us about the use and maintenance of the screw washer and so on. Screw washing machine is mainly used to remove impurities of sand product. The stone material to be processed by the screw washer is hard, and it needs to be exposed to the slurry during processing, and the cleaning can be completed by spiral rotation. For this kind of machinery, one of the daily notices is wear, and another one is rustproof. First of all, the new machine must be debugged and reused. In the process of use, it is also important to ensure that the incoming material is relatively uniform and continuous, and the side loading or filling should be avoided. Another important point is to start up the feed before opening machine and stop feeding materials after stopping machine.
