Spiral Classifier

Overview 

Spiral classifier is one of the ore-dressing machines. According to the different proportions of solid particles, the rate of precipitation in the liquid is also different. Spiral classifier concentrates fine ore based on certain principle. After grinding, the materials will pass through filter, through which the coarse materials will return to ball mill and the fine ores will be discharged from the overflow pipe. 

Application

Generally, the spiral classifier matches with ball mill to form a closed circuits for ore concentrating.  When used in the gravity concentrator, the combination can also grade ore and fine mud, and do particle size classification in metal slurry beneficiation process. Besides, this set of spiral classifier and ball mill can be used for washing off mud and dehydration. The machine is reliable, and easy to operate.

Composition and Classification

The classifier is mainly composed of the transmission, spirochetes, tank, lifting body, lower bearing (bearing) and discharging valve. And its classification is as follows:

1. High weir type: It's mainly used for the separator of ores with particle size between 0.83-0.15mm; 

2. Sank: It is mainly applied to the separator of ores with particle size between 0.15-0.07mm.
