The agitator has anchor type, frame type, paddle type, turbine type, scraper type, combined type. The rotating mechanism can adopt cycloidal pinwheel reducer, stepless speed reducer or frequency conversion speed control, etc., which can meet the special requirements of various materials. Response requirements. In fact, under different production process requirements, the required sealing performance and sealing structure of the stainless steel reactor are different. Therefore, when the customer chooses the reactor, the reactor should be sealed according to the actual production process requirements. Selection.
