Product Description

Spiral classifier is one of the equipment for ore dressing. The rotor adopts the central structure and the spiral rubber blade is installed on the central shaft. The reducer is connected to the central shaft for work. The working principle of spiral classifier is that the different specific gravity makes the sedimentation rate of solid particles different in the liquid. Spiral classifier works together with ball mill at ore dressing plant, forming a closed-circuit cycle to distribute ore and sand, or used at gravity mill to grade ore and fine mud, and metal dressing process for ore pulp particle size classification, as well as washing operations for desliming, dehydration and other operations. The machine has the characteristics of simple structure, reliable working condition and convenient operation.

The overflow spiral rubber blade is higher than overflow level, and the overflow spiral center is lower than overflow surface. The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm

The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank. Overflow weir is above the bearing center which is under screw shaft, and is underneath overflow end.

Compared with the hydro cyclone, the power consumption is lower. The main disadvantages are low classification efficiency, heavy equipment, and large floor space. Due to the limitation of equipment specifications and production capacity, it is generally not possible to form a closed circuit with a ball mill with a specification of Φ3.6m or more.

Application range Mainly used in the classification of various non-ferrous metal ore dressings such as quartz sand, gold, iron, aluminum, etc. It can also be used for the classification of materials such as pulp and ore.


Features of spiral classifier
1. Suitable for dry sand production lines of large and medium size.
2. The content of 0.00--0.75mm stone powder can be adjusted between 2% and 15%.
3. Long and narrow flume can make the best stirring effect, prolong the suspension time of materials in water.
4. Bolt-mounted wear-resistant lining plate can extend the wear life.
5. The classifier can be selected in single spiral and double spiral according to actual needs, and at the same time, the selection range of flume design is wide.
