LW type distillers mash with separation decanter centrifuge (Decanter centrifuges) allows distillers mash insoluble solids settling and dehydration, eventually resulting in a clear liquid and a relatively dry solid phase. For distillers mash of different crushing methods and mash fermentation and lees difference extracted solids concentration and particle size. The decanter centrifuge (Decanter Centrifuge) dewatering machine uses a special structure: the swash plate composite spiral, a spiral-shaped impeller bad mouth, arc-shaped drum taphole, anti-wear design; to meet requirements distillers mash separation and dehydration process of solid-liquid separation equipment.
