Ore Dressing Equipment Innovative Solid Bowl Decanter Centrifuge
1. Product introduction of sedimentation centrifuge
Sedimentation centrifuge is a new type of horizontal spiral unloading centrifuge, its working principle is the use of solid-liquid specific gravity difference, and rely on centrifugal force field to expand thousands of times, the solid phase is sedimentation under the action of centrifugal force, so as to achieve solid-liquid separation, and under the action of a special mechanism, respectively discharged from the body. When the centrifugal filtration because of solid particles easy to plug the filter medium and filter resistance is too large or too much fine particles leakage, the filter centrifuge can not achieve the ideal separation effect, at this time the sedimentation centrifuge has the incomparable advantages of the filter. The solid particles with small particle size can be separated from the liquid phase by centrifugal sedimentation principle.

3. Structural characteristics
Shafting sedimentation centrifuge has rigid shaft and flexible shaft. Generally, the running speed is not too high, the rotor diameter is larger, and the liquid flow is better centrifuge usually designed into a rigid shaft. The original research machine is designed for rigid shaft, its drum shaft diameter is large (Φ125mm), its critical speed is greater than the working speed, drum shaft and support bearing spacing is large (800mm), set a large size bearing, the height of the whole rotating shafting is also reduced, because there is no vibration problem when the critical speed, its vibration reduction structure is simplified accordingly. The spherical support usually required for flexible shafts is removed. Its advantage is that the working speed is lower than the first order critical speed, there is no vibration problem when the critical speed, can be operated in a wide range of speed. The structure of the rigid shaft itself can be set with large size bearings, which have a better stress state and can improve the life of the whole machine. Its disadvantage is that disassembly and maintenance is not easy to achieve full remote operation.
