Double spiral classifier is one of the equipment for mineral processing, which uses the principle that the specific gravity of solid particles is different, resulting in different sedimentation rates in liquid, to perform mechanical classification. This equipment can filter the material powder produced in the mill, and then use spiral blades to rotate the coarse material into the feed port of the mill, and discharge the filtered fine material from the overflow pipe. The double spiral classifier is abbreviated as a classifier. There are four main types of double spiral classifiers: high weir double spiral classifier and spiral classifier, submerged spiral classifier and double spiral classifier. The high weir type double spiral classifier is mainly composed of a transmission device, a spiral body, a groove body, a lifting mechanism, a lower support (bearing bush), and a discharge valve. The high weir classifier is widely used in ore dressing plants to form a closed circuit circulation path with a ball mill to separate ore sand, or in gravity ore dressing plants to classify ore sand and fine mud, as well as in metal ore dressing processes to classify the particle size of ore slurry, and in ore washing operations such as desliming and dehydration.

The high weir double spiral classifier has the characteristics of simple structure, reliable operation, and convenient operation.
The base of the submerged spiral classifier is made of channel steel, and the body is welded with steel plates. The inlet head and shaft head of the spiral shaft are made of pig iron sleeves, which are wear-resistant and durable. The lifting device is divided into two types: electric and manual.
Characteristics of Submerged Spiral Classifier
1. Used for the separation of ultra standard stone powder in the dry production process of machine made sand, it can be very convenient to control the content of machine made sand and stone powder, meeting user requirements [3].
2. Suitable for use in large and medium-sized dry sand production lines.
3. The content of 0.00-0.75mm stone powder can be adjusted between 2% and 15%.
4. The quality of stone powder is easy to control, and the fineness adjustment is convenient, flexible, and reliable.
5. The tile lining has a very low maintenance rate.
6. Adopting variable frequency control technology, the operation is more concise.
