the disc stack separator separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency. Inserting special plates (the "disc stack") provides additional surface settling area, which contributes to speeding up the separation process dramatically. It is the particular configuration, shape and design of these plates that make it possible for a disc stack centrifuge to undertake the continuous separation of a wide range of different solids from either one or two liquids. The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved in the specific application.

GQ for clarification: Heavy solid is deposited on the inner wall of the bowl and forms the sludge. And it will be
discharged by manual after the machine stops. The clear liquid flows out of outlet from the top of the bowl. It is mainly used for separating all kinds of suspension difficult to be separated, especially suitable for separation of solid-liquid suspension with light concentration, heavy viscosity, fine particles and very small differential gravity of the two phases. The motor connect with the big pulley and delivery the power to the spindle through the belt, tensioner and small pulley and rotate with the bowl in high-speed as the clockwise. The high speed tubular centrifuge is mainly used in liquid solid separation, liquid liquid solid separation in bio pharmacy, beverage, chemical industry. It is an ideal separation equipment by centrifuging, especially for those feeding with little gravity difference, and small dimension in diameter.
Decanter centrifuges process characteristics
The separation process in a decanter centrifuge relies on a few process characteristics such as centrifugal force or force, sedimentation rate and separating factor, differential speed between the conveyor and bowl, and clarity of the liquid discharge. Decanter centrifuges require a centrifugal force for the separation of the solids from the liquid. This characteristic is dependent on the radius of the centrifuge and its angular rotational speed. A decanter centrifuge applies a force equivalent to several thousand , which reduces the settling time of the particles. It is also favored to maintain a large force, which will result in an improved separation.
The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process. The
sedimentation rate is influenced by the particle size, the shapes of the particles, their differential densities and the viscosity between the particles and the liquid. This process characteristic can be improved by utilizing flocculating agents. The sedimentation rate is also dependent on the separating factor of the decanter centrifuge, which is related to the centrifugal force.
The exterior bowl and the scroll conveyor rotate at different high speeds. This differential speed between the two is accountable for the sedimentation throughout the decanter centrifuge cylinder. A high differential speed results in a smaller residence time of the cake settlement, so it is necessary to keep the cake thickness to a minimum to avoid impairing the discharge quality.
Keeping the cake thickness to a minimum also aids in the improvement of the cake dewatering process. For this reason, it is necessary to obtain an optimal differential speed to balance the cake thickness and quality.
The characteristic above all affects the clarity of the liquid output which is dependent on the volumetric throughout rate, where a higher flow rate will result in a poor liquid clarity. Another characteristic that influences the clarity of the liquid output is the differential speed. A low differential speed results in a better clarity, therefore, aiding in the separation process. The Force also plays a role in the clarity of the liquid discharge. Higher force results in an increase in the separation of the solid particles from the liquid and yields a better clarity.
the disc stack separator separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency.

With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel .

Palm oil is one of the world's most widely produced vegetable oils. It is the fruit of the oil palm tree, a tropical species that originated in West Africa, but now grows as a hybrid in many parts of the world, including Asia and Central America. Palm oil is used for a variety of purposes. The world demand for palm oil has soared in the last two decades, first for its use in food, consumer products and more recently as the raw material for biofuel. Palm oil is extracted in a multiple stage process.
The Shenzhou centrifuge enables three-phase separation, i.e. the simul- taneous separation of two immiscible liquids with different densities and one solid phase, provided that the solid phase is the heaviest phase. The most important difference from a decanter is the separate dis- charge of the two liquid phases. The Shenzhou centrifuge discharges the heavy liquid (water) via an adjustable impeller under pressure and the light liquid phase (oil) by gravity. The adjustable impeller allows ad- justing the separation zone inside the bowl and so the separation effi- ciency of the machine during operation. This optimizes the purity of the liquids and may possibly eliminate downstream equipment.
Crude palm oil (CPO) coming from the screw press passes through the vibration screen and is collected in the crude oil tank equipped with a heating device and optionally with a slowly rotating agitator. After the crude oil tank, a feed pump transfers the oil directly to the Shenzhou centrifuge by passing a de-sanding cyclone. In the Shenzhou centrifuge, the three- phase separation takes place providing clean oil, water and solids.
Benefits
Clean oil no need of clarification stage
Short processing time Minimum heat loss
Virtually no alteration of the oil (low FFA)
Minimum dilution water demand
Minimum waste water stream
Maximum flexibility
