A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

May 8, 2024. 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.

Abstract. Design features of the commonly used classifiers such as the spiral, rake, cone, bowl are described. Descriptions and design of centrifugal classifiers, such as the hydrocyclone, are given in some details. The mathematical aspects of designs that are related to operation of these classifiers and the theory behind the design and ...

High spiral classifier operation: the grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank.

Spiral Classifier is mainly used in pre-classification and examination classification of grinding loop in concentration plant and aggregate plant as well as desliming, dehydration in sand washing process and so on.

Now, the common classifiers in mineral processing plant are mainly mechanical classifier and hydrocyclone. Among them,mechanical classifier can be divided into spiral classifier, rake classifier,tank classifier and other types. With the development of classification operation, rake classifier is already replaced by spiral classifier, tank ...

Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types.

The first two, the RAKE classifier and the SPIRAL or screw classifier work on the same principal, and are not often used any more. These two types were popular for many years. It wasn't until the development of the CYCLONE type classifier that their popularity faded. You may still find a few though, in the older mills and the mills that ...

Basically the different wet classifiers are gravity settling tank, cone classifier, double cone classifier, hydrocyclone classifier, spiral classifier, and rake classifier. Gravity settling tank is the simplest type of classifier. Here the separation is based on the influence of gravity and terminal falling velocity.

The spiral classifier is widely used in the benefication plant to form a closed loop with the ball mill to split the ore, or to classify the ore and fine mud, grade the slurry during the spiral classifier mineral processing, and deslime and dewater in washing operations.

In the 1950s and 1960s, fine air classification was dominated by the static spiral air classifier which separates in a potential vortex. A lot of research work was carried out at that time to understand the separation mechanism of this classifier type ( Rumpf and Leschonski, 1967 ). With the beginning of the 1970s, the spiral air classifier was …

This work provides a comparison between the most commonly used classification equipment in the treatment of minerals - hydrocyclones and spiral classifiers - considering their applications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lot of their importance due to the development of cyclones. This …
