Deepa Screw Classifier Deepa Spiral Classifier is an ideal machine to wash and separate silt and other impurities as well as dewatering sand after wash. It combines both the functions of washing and dewatering and is very effective.

The sand settled on the tank bottom is collected, lifted by the screw conveyor and then drained and discharged. The screw diameter and consequently the classifier model, vary according to the water flow to be treat. The equipment drive is achieved by a gear motor directly fitted on the same axis as the screw.

The washed grit reaches the feeding pit of the lifting screw conveyor while the organics go out with the water or through a suitable flange. A low speed rotating shaft with proper arms improve the separation of organic from the grit. While is lifted up the grit is dewatered before reaches the outlet.

Coarse sand product exits the classifier through an airlock at the bottom. Air Classifiers 5 Control cost and accuracy Low operating cost and long life The secret to the low operating costs of the Air Classifier stems from its intelligent design. It eliminates the need for moving parts and reduces power draw by effectively

3 Classifier sand with a sieve screw filter perforated screen or Wedge Wire These machines offer great advantages: easy installation, don't require construction work, take up little space, it is fully closed to prevent the smells leakage, and low maintenance costs.

Water Clarifiers Process Engineers manufactures high capacity water clarifiers which separate fine particle solids (typically passing 200 mesh/74 micron or finer) by adding a treatment polymer to the incoming slurry from a cyclone, screw classifier, sand classifier and/or storm water. The polymer attaches to the solids in the slurry causing ...

At issue is the amount of water required for conventional washing methods; and a welcomed access to a new, economical lowwater washing solution. "A sand screw needs 50gallons per minute of water for every ton of minus200mesh in the feed," says John Bennington, director of washing and classifying equipment for Superior Industries.

Oct 05, 2008· Dear Sir, We are manufaturers of screw classifiers for stone crushing industry. These are used for sand reclamation. We use Spherical Roller bearings 21320 on either side of our 20' long screw. The problem is that the lower ie. feed side bearing (it's mounting) is always dipped in the SandWater solution. This is abrasive and damages the Oil seals used.

Spiral Classifier. Daiwo Machinery produces high type, single and double spiral, and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal oredressing, and desliming and dehydrating in washing.

SCREW CLASSIFIER. The dry feed material 05mm from the crushing plant and water is added in to the fabricated tank equipped with slow moving screw where decantation takes place with low turbulence with () 150 microns will be carried away by the flowing water moves in the opposite side and collected in and discharged outside. ...

NEW AND USED SCREW CLASSIFIERS FOR SALE. Nelson Machinery supplies used Screw Classifiers for sale worldwide manufactured by Quinn, Eagle, and more. They are also called spiral classifiers, sand screws, dewatering screws, fine material washers, and coarse material washers.

High Quality Screw Classifier, Sand Spiral Separator. Introduction of Stone Washing Machine, Spiral Classifiers For Dewatering Spiral Classifier also can be called spiral separator, screw classifier or screw separator. It is widely used in the concentrator and make up a closedloop with ball mill.

1997 Eagle Iron Works 8 X 28 Sand Classifier. Manufacturer: Eagle iron works This is an 8' X 28', 3C, 8 station classifier with Dial Split Controls; this machine was running when removed from service and will be emptied and washed out prior to sale.

Spiral Classifier has been widely use in closedcircuit grinding operations and it can also be used for the classification of ore sand and slime in gravity beneficiation plants, for the size grading of slurry in mineral processing plants and for desliming and dewatering in orewashing plants.

GRITSEP FGC is an innovative Sand and Grit Classifier designed using the most advanced simulation software. The GRITSEP FGC Fluid Dynamic Grit Classifier is the most compact, economical solution engineered for easy onsite assembly. Storage, transportation and .

Grit Classifiers consist of an inclined screw conveyor with a large volume hopper including an inlet spout and a water outlet spout, a shaftless screw housed in a trough, a lowfriction antiwear trough liner, a trough cover, an outlet spout for solid particles, and a drive unit mounted at the outlet end.

Spiral classifiers separate the fine waste material from the oversized material that needs to be sent back to the regrind circuit for further size reduction in ore processing. They also serve a dual purpose as a dewatering screw, when the amount of water on site is at a premium. If you have questions or would like an expert opinion regarding the configuration needed for your project, we are ...
