Automatic Operation Ore Dressing Equipment Horizontal Decanter Centrifuge
1. Working principle of sedimentation centrifuge Ore Dressing Equipment
A centrifuge for separating suspension components by centrifugal sedimentation. The suspension added to the drum forms a circular liquid layer under the action of centrifugal force, in which the solid particles settle onto the drum wall and form sediment. The clarified liquid is discharged through the drum overflow port or suction pipe, called separation liquid. The sediment is discharged manually or mechanically at the end of separation. Solid particles in the process of settling to the drum wall, but also with the liquid flow for axial movement, when the feed amount is too large, with the liquid flow to the overflow mouth, and has not settled to the wall of the fine particles with the separation liquid discharged to the drum, so that the separation liquid turbidity. For the difficult to separate suspension with small density difference between solid and liquid phase, small solid particles or large liquid viscosity, a sedimentation centrifuge with high separation factor should be selected to prolong the suspension's stay time in the drum (such as reducing the feed amount or using a long drum, etc.), so as to ensure the clarification of the separation liquid. Sedimentation centrifuge has a wide range of uses, especially suitable for centrifugal filtration because solid particles are easy to block the filter medium and filtration resistance is too large or fine particles leakage is too much suspension separation, but the moisture content of sediment is high. Sedimentation centrifuge can be used for crystallization, chemical precipitation, coal and other suspension separation, dehydration of sewage sludge and animal and plant oil residue clarification, etc.

3. Ore Dressing Equipment Decanter Centrifuge Drum structure and feeding mode
According to the research data of centrifuge developed abroad in recent years, the structure of rotary drum has positive cup type and inverted cup type, and the corresponding feeding modes are up feed mode and down feed mode. Scientific research machines and engineering machines in our country use inverted cup drum and feed system. The advantages are that the length of the main shaft is shortened, the superstructure is simplified, the slag discharge is smooth, and there is less pollution above the operation. The process pipeline is centrally arranged under the drum, which is conducive to the lifting, maintenance and solution of α seal of the drum.
