The classifier is mainly composed of transmission device, spiral body, trough, lifting mechanism, lower support (bearing) and discharge valve. Spiral Classifier Advantages: 1、Simple structure, easy to maintain. 2、Easy operation and stable performance. 3、Gravity connection with Ball mills; slurry pump conveying is not necessary.

Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

This work provides a comparison between the most commonly used classification equipment inthe treatment ofminerals -hydrocyclones and spiral classifiers -considering theirapplications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lotoftheirimportance due to the development ofcyclones.

Contact Now +86-. Published time：27 September 2023. The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral ...

Classifiers have found wide applications in the mineral processing industry. In this study, a novel enhanced gravity closed spiral classifier is presented. This device uses induced centrifugal force to classify particles. A functional prototype of the separator was 3D printed to experimentally validate the concept. The performance characteristics …

Spiral classifier is referred to as classifier, is one of the equipment in mineral processing. Classifier is a kind of classification device that depends on the principle-different solid particles proportion has different precipitation speed in liquid to classify minerals. It can filter out the minerals grain and powder after grinding.

A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due …

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 & …

The Spiral Classifier is available in three models with spiral diameters up to 120″. These classifiers have straight side tanks or modified flared or full flared tanks, and offer , 125%, and 150% spiral submergence.The spiral classifier is a size-classifying equipment used in the mining industry. It classifies minerals based on the principle that solid …

Sep 2016. Sidney Viana. This work concerns the application of a vibrating fork densitometer to the measurement of overflow density in spiral classifiers. A spiral classifier is a mineral ...

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 ...
