HR Series 2 stages Sea Salt Refining Pusher Centrifuge
This two - stage pusher centrifuge is applied in solid washing and solid - liquid separation processes. It can handle solids such as crystals, granules, or fibers, provided that their particle size exceeds 0.004 mm and the concentration is greater than 40%.
It finds extensive use in processing solutions related to various substances like NaCl, NH₄Cl, KCl, ammonium chloride, as well as other crystalline and granular materials.
Model: HR230N(P23),HR400N(P40),HR500N(P50),HR630N(P60), HR850N(P85),HR1000N(P100)

Working Principle
As depicted in the diagram above, when the basket rotates at its maximum speed, the suspension liquid earmarked for separation is introduced into the feeding pipe 1. From there, it is continuously channeled to the distributor 2. Under the influence of centrifugal force, the suspension liquid spreads evenly across the first - stage basket screen 3. A majority of the liquid phase passes through the screen mesh and the holes in the basket. Meanwhile, the solid phase remains on the screen in the shape of an annular filter cake.
As the first - stage basket moves back and forth, it propels the filter cake to advance a certain distance along the axial direction of the basket. During this process, as the first - stage basket moves, the empty areas on the screen are once again filled with the continuous flow of suspension liquid, which then forms a new filter cake. Through this continuous reciprocating motion, the filter cake moves forward in a pulsing manner and undergoes further drying.
Subsequently, the filter cake migrates from the first - stage basket into the second - stage basket. Once in the second - stage basket, the filter cake is loosened and redistributed on the second - stage basket screen. It is then pushed out of the basket and continuously enters the collecting tank 5. Finally, the filter cake is removed from the machine through the tangential discharge port by the scraper 4 installed in the second - stage basket. In the absence of the scraper, the filter cake would simply drop directly into the machine casting.

Salt centrifuge Configuration

Machine Casing
1. Casing
When looking at the front of the machine, a circular door can be observed on the casing. This door enables us to effectively monitor the machine's working condition.
Atop the casing, there is a feed pipe. Additionally, a screw conveyor for feeding purposes can be installed. Meanwhile, at the bottom of the casing, both the solid cake outlet and the liquid outlet are located.
Rear of machine
The equipment is equipped with a main motor and a pump motor. Among other components, there is a black back - oil pump and a variety of instruments.
Situated at the bottom of the machine is a counterweight. Its function is to balance the machine's gravitational pull. This is accomplished by filling it with concrete.


Inner of baskets
The setup consists of two baskets. The main motor is responsible for driving the rotation of these baskets. Simultaneously, the oil pump motor powers the pushing mechanism of the baskets.
Screens are affixed to the baskets. Their crucial function is to prevent solids from being carried away by the liquid during the separation process..
Baskets
A single centrifuge is equipped with two baskets, both of which are crafted from stainless steel.


Bearing
High quality FAG bearings to make sure the machine work well.
Motor
These are high - efficiency B3 motors that come with UL, CAS, and TUV certificates. They are adaptable to three - phase power supplies with voltages of 220V, 380V, 460V, or 660V, and frequencies of either 50Hz or 60Hz.
