The HR series centrifuge is a filtering centrifuge with horizontal double-stage piston pushing and continuous operation. The centrifuge can carry out feeding, separating, washing, discharging, etc. continuously when it is running at full speed. With such features as continuous operation, stable running, high separation factor, high production capacity, high output, good washing effect, low cake moisture content, low mother liquor solid content and etc., it is suitable for separation of suspensions containing solids with granularity higher than 0.08mm and concentration higher than 35%. It is widely used in chemical industry, chemical fertilizer, alkali making, salt making and other industries, and is especially suitable for solid-liquid separation of sodium chloride, ammonium chloride, ammonium bicarbonate, sodium sulfate, ammonium sulfate, etc.

The main motor drives the inner and outer bowls to turn at full speed. The materials are continuously introduced from the feeding pipe and are evenly spread onto the inner filter screen wall of the inner bowl. Under the action of centrifugal force, after passing through the filter screen and bowl filtration pores, the liquids are discharged outside the machine from the liquid discharging pipe. The solids are retained in the inner bowl and form circular filter cakes. When the inner and outer bowls are turning at the same speed, the inner bowl is pushed by the piston to continuously make axial reciprocating movements. Thus, the pushing disc pushes the filter cakes at the inner bowl to continuously move outwards and enter the outer bowl for further separation and formation of circular filter cakes after they are discharged outside the inner bowl. The outer face of the inner bowl will push the filter cakes at the outer bowl to continuously move outwards until they are discharged outside the outer bowl, and then discharged outside the machine after passing through the scraping groove.
