product details

Spiral classifier is based on the principle that the solid particles have different sizes and different specific gravities. Therefore, the sedimentation velocity in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink in the bottom of the tank and are pushed upwards by the screw. A grading device for mechanical grading. It can classify and filter the material milled out of the mill, then use the screw to push the coarse material upwards into the feed inlet of the mill, and discharge the filtered fine material from the overflow pipe. It is widely used in concentrators and ball mills. It is dubbed as a closed circuit circulation diverting ore, or used in the gravity concentrator to classify ore and fine mud, and the particle size classification of the pulp in the metal beneficiation process, as well as the operations such as desliming and dehydration in the washing operation.

Note: 1. Calculation of production capacity is based on the proportion of ore 2.7, overflow size 0.15mm (for high squat type) or 0.074mm (for submerged type).

2. Angle of inclination α = 14 ° ~ 18 ° 30 ° by the user according to the installation needs to customize.
