The spiral classifier adopts the working theory of different particle sizes and weights leading to different settling velocities. The fine mineral particles overflow and the coarse particles sink to the bottom of screw classifier and then are discharged from the upper end of the tank by the spiral shaft. The screw sand washer or screw classifier can filter the powder materials ground by the grinder and then screw the coarse materials to the receiving port of the grinding machine. Finally the filtered fine materials are discharged from the overflow pipe. The bottom of the spiral classifier is made of box iron and the main frame is welded with the steel board. The water head, shaft head of the spiral shaft is made of pig iron which features strong wear resistance. And there are two kinds of lifting devices: power driven one and manual operated one.

The spiral classifier or screw sand washer is widely applied by the dressing plant together with the ball mill as the closed cycle or applied to separate ore sand and fine mud by the gravity mill. There are many types of screw classifiers such as spiral separator and screw classifier. The screw sand washer is also used to grade the pulp particles in the metal beneficiation process and to remove mud and water in the ore beneficiation. Fote spiral classifiers have the advantages of simple structure, reliable performance and simple operation.

spiral classifier for mineral processing

spiral classifier for mineral processing

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesnt lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material will flow over the top and be travelling fast enough to be able to work its way downwards to escape. The Variables of these two types of classifiers are The ANGLE of the inclined bed, this is normally a fixed angle the operator will not be able to adjust it.

The SPEED of the rakes or spirals, the DENSITY of the slurry, the TONNAGE throughput and finally the SETTLING RATE of the ore itself.To be effective all of these variables must be balanced. If the incline is too steep the flow of slurry will be too fast for the rakes or spirals to separate the ore. If the angle is too flat the settling rate will be too high and the classifier will over load. The discharge rate will be lower than the feed rate, in this case. The load on the rakes will continue to build until the weight is greater than the rake or spiral mechanism is able to move. This will cause the classifier to stop and is known as being SANDED UP. If the speed of the rakes or spirals are too fast, too much will be pulled, out the top. This will increase the feed to the mill and result in an overload in either the mill or classifier as the circuit tries to process the increased CIRCULATING LOAD.

The DENSITY of the slurry is very important, too high the settling will be hampered by too many solids. Each particle will support each other preventing the heavier material from quickly reaching the bottom of the slurry. This will not allow a separation to take place quickly. The speed at which the slurry will be travelling will be slow and that will hamper effective classification. Another variable is the TONNAGE. All equipment has a limit on the throughput that anyone is able to process, classifiers are no different. This and the other factors will have to be adjusted to compensate for the last variable, the ore itself. Every ore type has a different rate of settling. To be effective each of the previous variables will have to be adjusted to conform to each ones settling characteristics.

The design of these classifiers (rake, spiral, screw) have inherent problems, First, they are very susceptible to wear, caused by the scrubbing action of the ore, that plus all of the mechanical moving parts create many worn areas to contend with. The other problem that these classifiers have is that they are easily overloaded. An overloaded classifier can quickly deteriorate into a sanded-up classifier. Once that happens the results are lost operating time, spillage and a period of poor Mineral Processing and Separation performance.

Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward the top of the trough.

The slurry is fed continuously near the middle of the trough. The slurry feed rate is so adjusted that fines do not have time to settle and are carried out with the overflow .liquid. Heavy particles have time to settle, they settle to the bottom of the trough and the spiral conveyor moves the settled solids upward along the floor of the trough toward the top of the trough/the sand product discharge chute.

The spiral classifier also named the screw classifier or the spiral classifier machine works as a type of sand classifier or screw sand washer by using the working principle of materials with different particle sizes and weights tending to sink in the liquid at different speeds.

The fine ore particles will swim in the water and then flow out while the coarse ore particles will sink into the bottom of the tank and then be discharged upward by the sand classifier or screw classifier, thus completing the mechanical separating process. Spiral classifier or screw sand washer is one of mineral processing equipment. With the principle of different particle size rate and there is different precipitation speed in the liquid, spiral classifier machine can conduct classifying work.

Fote which is famous for the reasonable spiral classifier price, and has made advanced screw classifiers which are used by the ore beneficiation plant to work together with the ball mill as a closed cycle to realize the classification of the mineral sand, by the gravity mill to classify the mineral sand and fine sand, by the metal beneficiation plant to realize the particle gradation of the ore pulp, and by the ore washing plant to do the desliming and dehydration work.

The spiral classifier machine or sand classifier is mainly made up of transmission gear, spiral device, tank, lifting structure, bottom support (bearing bush) and the ore discharging valve. It features the simple structure, reliable performance and easy operation.

The magnetic separation process, also named the magnetic separating production line and made up of jaw crusher, ball mill, classifier, magnetic separating equipment, concentrator and dryer, is a wet and dry separation combination method of magnetite.

The flotation separation process also known as the flotation separating production line realizes the mineral particle separation based on the working principle of different physical and chemical properties of the minerals leading to different floatability.

DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE Spiral Classifier is ideally suited Sizing applications, Washing Applications, and Dewatering sand or crushed material from Hydro cyclone, or lower screen residues.

DOVE Coarse and Fine Spiral Classifiers are supplied in various capacities, tub lengths, screw sizes and technical specifications. We supply total of 16 models, where 10 models are configured with single screw and 6 models with dual screw.

Spiral Screw classifier is a type of common mechanical classifier, consists primarily of an inclined tub and a transport screw for the coarse material. The fine material residue is at the lower end of the tub and the coarse material residue is at the upper end. The principle of the operation and separation of solid grains is based on the law of gravity and concept that the solid particles are different in size and specific gravity, therefore the settling speed in the water is different. Fine ore particles float in the water and overflow, and respectively coarse ore particles settles to the bottom. As a guide line, a unit with longer length classifier will dewater the same material to a higher degree, and likewise a unit with a greater diameter of screw revolving the identical speed will produce higher capacity. In the application of dewatering fine material, the screw speed is reduced to allow proper classification and dewatering.

DOVE laboratory will assay your ore samples rapidly and analyze your raw materials and recommend the most efficient processing plant according to the ore specifications, minerals composition, and ore assay results, and your project size and the geologic and topographic conditions of your mine.
