The advantages of centrifugal casting – Using centrifugal casting, parts have greater strength because grain structures are denser. Its mechanical properties are almost equal in all directions, as the process allows for more control over directional solidification. As a result of this increased structural density, the component has a longer life span and is more stress tolerant. The improved structural uniformity and reduced internal porosity of the components also contribute to enhanced part strength.
The variable pump impeller technology can adjust the thickness of the liquid layer inside the machine while it is running, so that the Decanter centrifuge can be quickly adjusted without stopping to achieve separation effect. New independent drive system. The structural feature of the new independent drive system is that the drive of the rotary cylinder and the screw are respectively driven by two vertical variable frequency motors. A new type of gearbox is used to connect the drum and the screw. In addition to withstanding high torque, this gearbox can also independently rotate the screw without the drum rotating. Through the above discussion and analysis, it is not difficult to see that the influence of structural design on the processing capacity of decanter centrifuge is mainly reflected in the selection and design of mechanical parameters and corresponding auxiliary equipment. If each problem is considered comprehensively and concretely, it can also be considered comprehensively and concretely. The decanter centrifuge can better serve the solid-liquid separation field of various industries in our country.
The fundamental principles of operation for the 2 phase decanter centrifuge and 3-phase Shenzhou Machinery decanter centrifuges are identical to those of the horizontal decanter centrifuge. To separate substances with different densities, the equipment uses a high-speed rotating assembly to create an acceleration inside the bowl that is thousands of times stronger than gravity. Then, the relative motion between the bowl and the screw is generated by the differential gearbox, allowing for the separation of the substances. In contrast, 3 phase decanter centrifuges use centripetal pump technology to achieve solid-liquid-liquid three-phase separation, as opposed to Shenzhou Machinery 2-phase centrifuges, which are utilized for solid-liquid two-phase separation and discharge the solid slag and separation liquid from an opening at the bottom of the equipment collection box. Under the pressure of the centripetal pump, the heavy liquid phase is discharged through the flow outlet on the impeller. In contrast, gravity sends the solid slag and light liquid phase down from the bottom opening of the equipment collection box.
Disc stack centrifuge is a kind of vertical centrifuge.As a high efficiency,high output,high automation and high-speed precision separation equipment,it can be divided into solid-liquid two phase and solid-liquid-liquid three phase separation,As a two phase separation disc centrifuge,it can separate most solid particles and liquids,As a three phase disc centrifuge,it can separate liquid phase of different densities and separate solids at the same time. It can separate suspensions with a solid concentration of less than 5%. The technical parameter range of disc centrifuge is relatively large, and the diameter of the drum is generally 150 ~ 730 mm. The disc centrifugal separator can provide a better result of separation with a clearer centrate, and can be adopted in more areas with its wide range of technical parameters.

The structure and working principle of a Decanter centrifuge – The Decanter centrifuge relies on the density difference between solid and liquid phases, and under the action of centrifugal force, accelerates the settling speed of solid particles to achieve solid-liquid separation. There is a conical section designed in front of the drum, which rotates at a set speed according to the different properties of the material. The material rotates at the design speed on the inner wall of the drum, forming a concentric liquid layer along the drum shell, called the liquid ring layer. The solids contained in the material are deposited onto the wall of the drum under the action of centrifugal force, and then the dry material is pushed out of the drum through spiral operation. The operating speed of the drum directly determines the separation factor, while the speed difference of the screw directly affects the solid moisture content transported outside the drum. It has a direct impact on processing capacity, residence time, and solid discharge.
