Grit Classifiers are used to separate materials. A shaftless spiral extracts the material, eg sand, that settles at the bottom of a trough. The shaftless spiral allows the material to travel automatically through the system to a recovery or disposal container. Our Grit Classifier is strong and Built to Last ®.
Spiral/Screw Classifier Speed. The speed of the conveyor should be just sufficient to handle the sands to be removed. The slower the speed the less the agitation in the pool and the finer the overflow. The lower the speed the longer the life of the classifier and all wearing parts. When and Where to use a Screw-Spiral Classifier
Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals. The bottom of the classifier is ...
Spiral classifier solutions Dewatering Dewatering Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.
Safety and easy operation 4. High efficiency Brief Introduction to Spiral Classifier Spiral classifier, which can also be called spiral separator, is one of the ore dressing equipment which classifies the materials using the principle that different solid materials have different settlement speed in the liquid due to the difference in proportion.
A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the ...
Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow . The spirals impede …
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles …

Spiral Classifier Working Principle 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 produces 2 kinds of products, the production of this tool is taken results in dilute conditions and condensed conditions. So that the resulting data is more percentage. Valve openings are set with , 70% and 40% data. Maximum speed of this tool is 60 rpm. To know the production at
The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster …
Spiral classifiers are generally preferred as material does not slide backwards whi ch occurs in rake classifiers when the rakes are lifted between str okes. This also allows spiral classifiers to ...
But that's not the only type of sprial sand classifier for mineral extraction. Circular screens are also a practical option for smaller mineral separation tasks. If you are working with grains, linear vibrating screen models could be a better option. These models usually have rectangular table tops and feature sieves on the underside to allow ...
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.
EIMCO-K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening.
Bi-spiral steel classifiers [8], [9] are one of strategic components of the OCP plants. Altogether in three OCP production regions 29 pieces of such equipment are in operation. Their task is to separate grains in terms of size and weight in a water environment due to the gravity force action [10], [11].Classification products comprise: …

Thus, Spiral behaviour to different operating parameters has been predicted qualitatively by many authors. Besides it, many authors attempted to predict the performance of spiral quantitatively but the successfulness is limited (Holtham 1992 and Loveday 1994). In the current work, spiral behaviour has been studied subjecting to different
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.
