High Weir Spiral Classifier

【Introduction】:
Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry.
【 Capacity 】:
10~1785 t/d
【Improvement】:
An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation.

【Advantages】

The overflow spiral 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

【Product Structure】

High spiral classifier operation: 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.

【Successful case】

High-Weir-Spiral-Classifier

A concentration in Guangxi often wasted a lot of resources due to uneven ore particle size, then the client found Xinhai spiral classifier manufacturer through search engine. According to the customer requirements and existing equipment configuration, Xinhai technical personnel recommended high weir spiral classifier who can pre-classify. The hierarchic flooding size of Xinhai high weir spiral classifier is equal or greater than 0.015 mm, which meet the needs of customer, and it also has a remarkable application effect, the recovery rate increased by 15%.
