Spiral Classifiers. The Akins, Hardinge, and Western Machinery are examples of the spiral. The first two consist of a spiral rotating in an open steel trough or box set on a slope, the spiral working the sand to the upper end and the slime overflowing at the lower end. Spirals of 8 to 12 inches diameter are available for small plants.
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 ...
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. Many locations don't have a ready source of water, so when used as a ...
First Online: 13 April 2023. 3 Accesses. Download reference work entry PDF. Spiral classifier is used for material classification with spirals used to stir and convey …
An alkaline slurry from a bauxite grinding mill was scheduled to be classified using a spiral classifier at the underflow rate of 1100 t/day. The width of the classifier flight was 1.3 m and the outside diameter of the spiral flights was 1.2 m.
Spiral Classifiers are widely used in the distribution of ore in closed circuits with ball mill in mining processing, in order to get a certain degree fineness of ore particles, meanwhile increasing the efficiency of grinding. This machine can also be use. 500-2000mm Feed Size. 1.1-15KW Motor Power.
Ghana Manganese Company (GMC) has renovated their oxide washing plant by integrating it with a spiral classifier to make a batch system operating process. Particle size of <3.35mm (Mn grade of 43-47%) obtained from the primary section of the plant served as feed to the classifier and with the plant condition (i.e. at 60 min washing time, 30 ...
Spiral classifiers and cyclones are the machines used in closing the grinding circuits in mineral beneficiation plants, with the latter having certain advantages that determine its use in large ...
Wet Pan Mill also known as amalgamation grinding mill, gold grinder mill, which is a versatile ore grinding pan mill for wet materials. It's the best replacement for a medium-small capacity ball mill, owing to the excellent performance for wet crushing, small investment, and high output, widely used for separating gold, iron, molybdenum, lead, …
The Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with , 125%, and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. The spiral classifier is one of the size-classifying equipment for the mining industry.

Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

The shape of the spiral classifier is a rectangular chute with an inclination angle of 12°- 18.5°. The bottom is semicircular, and one or two longitudinal shafts are installed in the groove. The spiral blades are continuously arranged along the shaft length, and the spiral shaft is driven to rotate by the upper end transmission mechanism.
Spiral jet mills: spiral flow of the grinding gas ... They collide with each other again and again and are thus comminuted. A classifier wheel rejects those particles that are still too large and transports them back into the fluidised bed. The particles that are fine enough are separated from the grinding gas by a separator or dust filter.
