Spiral classifier also can be called spiral separator, screw classifier or screw separator. It is widely used in the concentrator and make up a closed-loop with ball mill.
We produce high weir type classifier, single and double spiral type classifier and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the separation of ore in closed circuits with ball mills for the grading of ores and metal ore-dressing and other operations.
This product is featured with simple structure, reliable working condition and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to float in the water, while coarse ore sinks to the bottom.
Features and benefits
1. Can be very convenient to control the content of sand powder and to meet usersâ?? requirements.
2. Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line.
3. The content of powder with size of 0.00--0.75mm is between 2%-15% and can be adjusted.
4. The quality of powder is easy to control. The adjustment of fine is convenient, flexible, and reliable.
Working principle
The principle used in spiral classifier is that different sizes of crushers have different weights, so their sedimentation rates are also different. In the working process, fine ore grains float on the surface of water, and rough grains sink on the bottom of the cell. Screw grader can classify materials from mill, and then bring the rough grains to the entrance mouth of mill with the help of flights, and discharge the fine ore grins though pipe. The pedestal spiral classifier is made of box iron. The body is made of welding steel plates. The faucet and spindle nose of screw shaft are made of pig iron set which is wear-resisting durable. The take-up sets include two types power-driven and manual operation.
Spiral classfiers in pioneers machinery factory suitable for dewatering, medium, desliming and spraying in ore dressing for medium and fine naturial wet and dry classifying in mine. Pioneers classifying machine is mainly used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 14-325 meshes are classified. Waste mud or water for ore sand can be separated from the ores.

Shaking tables are designed to wet gravity-based separation of minerals and other granular materials. There are many applications where the concentrating table is of particular value and cannot be equaled for economical and efficient performance. Application Shaking tables are used to treat a great variety of materials, ranging from heavy material, ranging from heavy sulphides (specific gravity 7.5) to coal (specific gravity 1.3), at some cases below 50um.

The ore mined is first brought to jaw crusher for preliminary breaking, and after broken to reasonable fineness evenly taken into ball mill by hoist and vibrating feeder for crushing and grinding. The fine ore stuff grinded by the ball mill enters into the next process: classification. The spiral classifier uses the principle that solid particles of different proportion have different settling velocity in liquid to cleanse and classify the ore mixture. When the cleansed and classified ore mixture passing the magnetic separator, the magnetic materials contained in the mixture will be separated by magnetic force and mechanical force due to their different specific magnetization coefficient. And then the mineral particles that are preliminarily separated by the magnetic separator are sent to the flotation machine and mixed with different chemicals according to the characteristics of different minerals contained to separate the targeted minerals from other materials. After the targeted minerals are separated, as they carry a lot of moisture, they must be preliminarily enriched by the thickener and dried by the drier and then dry minerals can be got.
