When spiral classifiers for sand washing and dewatering, the production capacity is generally calculated according to the amount of sand returned, and the control particle size and allowable feed flow rate are checked according to the overflow speed.. 2.Hydrocyclone. Hydrocyclone is a type of classifier that is for the fines classification and dewatering by …
The products of this type are sand and slime. These machines have large capacity or circulating loads and can be adapted to washing ores and sands of not too large a size (see Fig. 117 for a mill and classifier in closed circuit). Spiral Classifiers. The Akins, Hardinge, and Western Machinery are examples of the spiral.
However few models provide a method to account for wash water addition and the opening of concentrate ports that are two strategic variables for the operation of …
The spiral washing equipment is mainly used for mixing, washing, separating and desilting of minerals. It is also used for stone cleaning in construction, power station and other projects. Its flushing water pressure is less than 147-196kpa. Our spiral washing machine is suitable for the pre-cleaning of silt in iron, manganese, limestone, tin ...
Clay mine needs a Trommel scrubber for washing without clay ore needs a Trommel screen and vibration screen to separate different sizes. ... It works together with the spiral classifier, so the overflow slurry from the classifier is about 80% 200mesh powder. The oversize particle from the classifier will go back to the ball mill grinding again ...
Sand Washing and Desliming. Silica sand pumped from the pit is passed over a screen, either stationary, revolving or vibrating type, to remove tramp oversize. The screen undersize is washed and dewatered generally in a spiral type classifier. Sometimes cone, centrifugal and rake type classifiers may also be used for this service.
Spiral classifiers are widely used in the ore dressing plant to match the ball mill with a closed-circuit cycle to split the ore sand, or in the gravity ore dressing plant to …
In the sedimentation tank the wash water is reclaimed and sent back to the washing operation again. The solids are removed by and dewatered in the discharge spiral and can be sent to re cycling if this is considered of value. Robust design fo reliable operation Like the spiral classifier the spiral dewaterer consists
Download reference work entry PDF. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the …
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 processing processes, particle size classification, desliming, dehydration, and …
The result of that the 900mm spiral classifier has the best beneficiation effect in the cases of the same grade concentrate ore. The scavenging effect of 900mm pitch spiral separator machine has the output of 3.42t/h, the productivity of 32.18%, the grade of concentrate mineral 17.46%, recovery rate 17.16%, and comprehensive efficiency of …
Washing and classifying equipment provides producers with the ability to remove excess water and deleterious materials such as clay, silt, shale, coal, soft stone, roots, twigs and other debris from the rock. If not washed, construction material containing deleterious materials can cause cracking in structural projects and prevent drainage in ...

Spiral is suspended between two bearings, operating with a bed of sand between the screw and the tank, improving dewatering and eliminating tank wear common with ...
on a slope, with interrupted rake or spiral blades to move the settled solids to a central discharge cone. Tank diameters vary from 4 to 250 ft. Tank depths at center are 2 to 3 ft for small units and up to 25 ft for larger units. Hydraulic classifiers of the sizer and super-sorter types, Figs. 7 and 8, are narrow, deep, rectangular
Washing, Classifying & Dewatering Sand Screws. Designed to handle fine materials up to 3/4″ (19mm) in size, these spiral classifiers effectively remove clays, silt, and lightweight contaminants from sand, ensuring a clean and high-quality end product. As the material progresses up the sand screw's incline, unwanted particles are washed away …
