Spiral sand washer is sand washing equipment, the spiral classifier is ore washing equipment(also can be used for sand washing). Due to their similar appearance, it is difficult for many users to distinguish. So what is the difference between spiral sand washing machine and spiral classifier?
1. Different Appearance
From the appearance point of view, the blades of the spiral sand washer machine and the spiral classifier for mineral processing are different. The blades of the spiral sand washer are solid blades, and the blades of the spiral classifier are suspended hollow blades.
2. Different applications
Spiral washer is mainly used for sand and stone cleaning, and bucket wheel sand washer is also a commonly used model. High-quality spiral classifiers are widely used in beneficiation factories, which combined with ball mills to form a closed loop to divert ore, grade ore sand and fine mud in gravity separation line, or grade pulp particle size and do desliming and dewatering in the mineral processing operation.
3. Different Working Principles
The spiral type sand washing machine needs to be arranged in an inclined manner. The lower part of the water tank is surrounded by a three-sided weir to form a sedimentation tank, and the screw head is immersed in the sedimentation tank. The screw is continuously driven and rotated by the motor through the reducer, and the cleaning water is supplied by the perforated plate at the bottom of the sedimentation tank. The screw sand washer has the functions of cleaning, dewatering, and grading.
Mineral processing spiral classifier is a device that discharges from the upper part of the spiral for material classification. Its working principle is that due to the different size and specific gravity of solid particles, the sedimentation rate in the liquid is different. Fine-grained ore floats and overflows in the water, and coarse-grained ore particles sink at the bottom of the tank. The spiral screw classifier can separate and filter the raw materials from the ball mill, and then grade the coarse and fine materials.
4. Different Types
Spiral sand washing equipment can be divided into the single screw and twin screw. The processing capacity of the spiral washer can be improved by increasing the length of the spiral sand washer or using double spirals side by side.
Spiral separators mainly include high weir single spiral and double spiral, low weir single spiral and double spiral, submerged single spiral, and double spiral. The low weir type spiral classifier is rarely used, and the high weir type and the submerged type mining processing equipment spiral classifier are commonly used.
5. Different Processing Capacity
The blade area of the spiral sand washing machine is larger, which can transport more sand and gravel. The processing capacity of the spiral sand washing machine is about 2-3 times that of the mining spiral separator of the same specification.
6. Different Sand Washing Effects
For the same size of equipment, the silo of the spiral sand washer is larger than the silo of the spiral classifier, and the time of the sand settling will be longer, so the treated sand will be cleaner.
The above are the 6 differences between the industrial spiral classifier and the spiral sand washing machine. For more information about the prices, technical parameters, and videos of them, you can contact our online engineers at any time.
