Spiral Classifying Equipment Description

The Spiral Classifying Equipment can be divided into single and double spiral classifying equipment according to the number of spiral shafts. It can also be divided into three types of high weir type, low weir type and submerged type according to the weir height.

Overflow weir of high weir Spiral Classifying Equipment is positioned above the lower end of the spiral shaft center, but lower than the upper edge of the overflow end of spiral. It has a certain settlement area suitable for coarse particle, which can obtain an overflow particle size of more than 100 meshes.

Overflow weir of low weir type spiral classifying equipment is below the center of the overflow end bearing. Therefore, the settling zone area is small and the overflow production capacity is low. It usually needs no classifying work and is used to wash the ore from soil.

The whole spiral at the overflow end of the submerged spiral classifying equipment is submerged in a settling zone under the liquid level. The settlement area has a larger area and depth. It is suitable for fine grading and can obtain the overflow particle size of less than 100 meshes.

Working Principle

Finely ground slurry enters the inlet tank from the material inlet located in the middle of the settling zone. The lower end of the inclined installed water tank is the sedimentation zone of slurry classification. The spiral rotates with a low speed and stirs the slurry. It makes the fine particles suspend above and flow to the overflow side weir. It enters the next process, and the coarse particles settle to the bottom of the tank and are conveyed to the discharging port by the spiral to be discharged as returning sand. Usually spiral classifying equipment and mill compose a closed circuit and returns the coarse sand to the mill for regrinding.

The advantages of spiral classifying equipment are simple structure, stable and reliable work and convenient operation, which makes it easy to form a closed circuit operation with the mill of which the diameter is less than 3.2 m.
