Spiral classifier features Spiral classifier works

Spiral classifiers mainly include sorghum type single helix and double helix, low enthalpy single helix and double helix, submerged single helix and double helix several grading machines, low enthalpy type is rarely used, mainly sorghum type and Submerged and XL spiral classifiers. The following Xiao Bian will introduce to you the characteristics and working principle of the spiral classifier. Let's take a look.

Spiral classifier works

Spiral classifier is based on the principle that the solid particles have different sizes and different specific gravities, and thus the settling velocity in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink to the bottom of the tank. A grading device for mechanical grading by pushing up the screw to the upper part, which can grind the material powder in the mill to filtration, and then screw the coarse material into the feed inlet of the mill with the screw blade and filter it. The fines discharged from the overflow pipe. The base of the machine adopts channel steel and the body is welded with steel plates. Screw head into the water, the shaft, the use of cast iron sleeve, wear-resistant and durable, lifting device sub-electric and manual two.

Spiral classifier classification

1. Sorghum-type: the top of the spiral end of the overflow end is higher than the overflow surface, and the center of the overflow end is lower than the overflow surface. Mainly used for the classification of ore with overflow size of 0.83-0.15mm;

2. Submergence: The spiral blades of the overflow end are immersed below the overflow surface. It is mainly suitable for grading ore with an overflow particle size of 0.15-0.07mm.

Model Description: Example "2FG-15" Among them, "2" represents a double helix, single spiral is not marked; "F" represents a spiral classifier; "G" represents a high jaw type, or marked "C" represents a sinking type; 15" indicates the helix diameter of the classifier in dm.

Spiral classifier application

Spiral classifier is widely used in the separation plant and the ball mill dubbed closed-circuit flow path split shunt ore, or used in the gravity concentrator to classify ore and fine mud, and the metal ore beneficiation process in the size of the pulp, and washing In the operation of mud removal, dehydration and other operations.

Spiral classifier features

1. For the separation of super-standard stone powder in the process of sand drying process, it is very convenient to control the content of gravel powder to meet the requirements of users.

2. It is suitable for use in dry and medium-sized sand production lines.

3, 0.00 - 0.75mm stone powder content is adjustable between 2% -15%.

4, stone powder quality is easy to control, fineness adjustment is convenient, flexible and reliable.

5, tile lining, maintenance rate is very low.

6, using variable frequency control technology, the operation is more concise.
