Pusher centrifuge can be divided into horizontal pusher single-stage, two-stage or three-stage that is operating continuously. They can perform feeding, filtration, washing and discharging in sequence at their full-speed running. They have the advantages of continuous operation, stable performance, large capacity, ideal washing effect, low moisture content of cake and less solid content loss. They are suitable for separating the suspension with solid particle size of more than 00.8mm, with the concentration rate of over 40 %. Suitable for industries such as chemical engineering, chemical fertilizers, alkali and salt making, particularly for the solid-liquid separation of sodium Chloride. ammonium chloride, ammonium bicarbonate, sodium sulfate, urea and so on.
