Benco's spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. By combining the proper submergence of the spiral with one of the tank designs a choice of 63 combinations is possible in Straight, Modified or Full flare tank designs. The proper combination of pool depth, area and spiral construction is important to secure a controlled turbulence in the slurry flow for accurate size separation.
As one of the important part of beneficiation line, spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. According to the theory that the deposition rate are quite different because of the difference of different solid particles' specific gravity, the spiral classifier is not only able to clean the ground mineral ore, but also separate the particles briefly. The big particles will be conveyed to the grinding machine again and the fines will be transported to the subsequent beneficiation equipments.
Spiral Classifiers are usually suitable for the following situations:
--Separation of fine particles and liquid from coarse particles--Separation of light particles from heavy particles
--Separation of the particles into a number of products graded according to size
--Separation of liquid from solid particles
Main benefits of Spiral classifiers:
--Energy saving--Heavy duty, rugged construction
--Powerful self-contained spiral lifting device
--Continuous spiral raking
This machine is the main equipment in mineral dressing plants, for grading ore pulp size. It is also used for dewatering and other works in sand washing. It’s divided to single spiral and double spirals; according the difference of spiral’s depth in overflow surface, it’s also divided to high weir type and sinking type.
For different types and detailed specifications, please feel free to contact our company. Your any kind inquiry will be highly appreciated.
