Case Detail

Spiral sand washing machine and spiral classifier, one is sand washing equipment, and the other is beneficiation equipment (can also be used for sand washing), but because of the similarities in appearance, many users are stupid, even some people I think they are almost the same in appearance. How to distinguish

1. Shape

Since many people think that there is a great similarity in appearance between the spiral sand washer and the spiral classifier, let's take a look at the difference in appearance between the two.

The more obvious is the difference between the two blades. The blades of the spiral sand washing machine are solid blades, and the blades of the spiral classifier are hollow hollow blades, as shown in the following figure:

2. Principle

The spiral sand washing machine needs to be arranged at an angle. The lower part of the water tank is surrounded by a three-sided weir plate to form a sedimentation tank. The spiral head is submerged in the sedimentation tank. The spiral is driven by the motor through the reducer to drive continuous rotation. Three functions: cleaning, dehydration and classification.

The screw classifier is based on the principle that the solid particles are different in size and specific gravity, so the settling speed in the liquid is different. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank. A device that performs mechanical grading by pushing the screw upward to discharge it. It can filter the powder milled in the mill, and then screw the coarse material into the feed port of the mill using the spiral piece, and discharge the filtered fine material from the overflow pipe.

3. Application

The spiral sand washer is mainly used for the cleaning of sand and gravel, and the wheel sand washer is also commonly used. (For the difference between the two, please read "Spiral sand washer is not as good as wheel sand washer? How did this" prejudice "come from?") The output of spiral sand washer is related to its length and width.

Spiral classifiers are widely used in beneficiation plants to be combined with ball mills to form closed-loop shunt ores, or used in gravity beneficiation plants to classify ore and fine mud, and to perform particle size classification of ore pulp in metal beneficiation processes, as well as dewatering in washing operations. Mud, dehydration and other operations.

4. Processing capacity

In terms of sand washing operations, since the area of ​​the blades of the spiral sand washing machine is larger, more sand and stone materials will be transported at the same time, and the processing capacity is about 2-3 times that of the classifier of the same size.

5. Sand washing effect

For equipment of the same size, the bin of the sand washing machine will be larger than that of the classifier, and the sand precipitation time will be longer, so the washed sand will be cleaner.

6. Type

The spiral sand washer is divided into single spiral and double spiral, and the processing capacity can be increased by increasing the length of the sand washing machine or the double spiral side by side.

Spiral classifiers are mainly high weir single spiral and double spiral, low weir single spiral and double spiral, submerged single spiral and double spiral, low weir type is rarely used, mainly high weir type and submerged type.
