The submerged spiral classifier is suitable for fine particle classification, and the classificaiton overflow particle size is generally less than 0.15 mm. Compared with these two kinds of spiral classifiers, the hydrocyclone has a better classification effect when classifying finer-grained materials (the classifying size is generally 0.3-0.01 mm).
The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

The spiral classifier is one of the important equipment in the mineral processing process. Its principle is to use the difference in the settling speed of solid particles in the liquid to classify materials.
The overflow height H of the high spiral classifier is 1/4–3/8 of its spiral diameter D, and is mainly used for ore classification with an overflow particle size of 0.83–0.15 mm. The H of the submerged spiral classifier is 3/4–1 of D.
The application range of spiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser …
Spiral Classifier, Dewatering Screw. This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values.

Common classification equipment includes spiral classifiers and hydrocyclones. The 2 kinds of equipment have different classification effects because of their different structures and working principles. This article will introduce the working principle and characteristics of hydrocyclone and spiral classifier. 01 Hydrocyclone (1) …
Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.
The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster …
Spiral classifier is mainly composed of the driving device, the spiral body, the groove body, the lifting mechanism, the lower seat and discharge valve. The machine base adopts channel steel, the body adopts welded steel plate. Screw shaft parts use the pig iron, and wear resistance. Working Principle:
Spiral classifier is made of U-steel, while the body is armor plated and the spiral axle is made of cast iron for durability. The machine's lifting equipment can be used manually or electronically. Spiral classifier consists of transmission part, spiral axis, tank, elevator mechanism, bearing, discharge valve.
A spiral classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. ...
