Spiral Classifier is classic mineral processing equipment used for the classification of equipment, concentrator-grinding circuit in the pre-grading and inspection Charles classification, washing, removing mud and other operations. It uses gravity or centrifugal force according to the settlement of particles in the pattern of fluid material grading equipment. The Spiral Classifier that NHI China offer can be divided into high weir type and the sinking of type two. High weir type suitable for coarse classification, the classification overflow size is generally greater than 0.15mm. Sunk screw classifier is suitable for fine grading and the grading overflow particle size generally less than 0.15mm. NHI China are an eminent Supplier of Spiral Classifier in China.

  As the important part of beneficiation line, spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements. According to the theory that the deposition rates are quite different because of different solid particles' specific gravity, the spiral classifier is not only able to clean the ground mineral ore, but also separate the particles briefly.     Pretreatment: Using the hydraulic hammer to crush the big stone into smaller one, and arrange the worker to cut through the long reinforcement to prevent damaging the belt conveyor.

Spiral Classifier is widely used in different particle ore,grading pulp and process of ore desilter in the concentrator. Features 1. Simple structure, reliable running and easy operation.2. It mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity.3. It can classify the ground material powder from the grinder, spiral the coarse grain into material inlet of grinder through the spiral chip, and discharge the classified fine grain from overflow surface.4. Its base is made from channel steel, and its body is welded from steel plate.5. The lower support of spiral bearing is of engine-bearing structure of good wear-resistance and durability.6. The lifting device is of electric and manual mode. Working Principle The flotation cell is driven by a motor triangular substituting transmission when impeller rotates,on the one hand, suction sufficient air is mixed with the slurry, on the other hand, stir the slurry mixed with the drug while refinement of the foam, make the mineral adhesive above of the foam. To adjust the height of the gate and to control of the liquid level are the useful ways for foam scraper by being scraped off. Processed Materials : Spiral classifier is beneficiation equipment. Because of the principle that solid particles with different specific gravity will get different deposition rate in liquid, spiral classifier can realize mechanical classification effectively. This machine takes advantages of simple structure and reliable running. Applications : Widely used in combine with ball grinder into closed circulation for ore-sand separation in the ore separation plant; classify ore sand and fine sludge in gravity ore separation plant; classify the grain of ore pulp at the metal ore separation process; and remove sludge/water at the ore separation process.

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. In general, the products resulting are (1) a partially drained fraction containing the coarse material (called the underflow) and (2) a fine fraction along with the remaining portion of the liquid medium (called the overflow).     The classifying operation is carried out in a pool of fluid pulp confined in a tank arranged to allow the coarse solids to settle out, whereupon they are removed by gravity, mechanical means, or induced pressure. Solids which do not settle report as overflow.   EIMCO-K.C.P.  Spiral Classifiers are mechanically the devices are powerfully built, and functionally they are versatile and flexible.   Today’s worldwide acceptance of EIMCO-K.C.P.  Classifiers for washing and dewatering pulps, and in closed-circuit grinding is the result of many years of experience in solving wet classification problems. Because users’ needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user’s classification requirements.   Spiral diameters (0.3 m to 2.25 m):   Important in establishing a correct balance between overflow and raking capacity. Bears directly on accuracy of separation and control of agitation.   Spiral pitches (single / double / triple):   Number of ribbons is a factor in controlling degree of agitation. Each ribbon of advanced pitch gives greater raking capacity than equivalent ribbon of spiral using lesser pitch. Triple ribbon spiral highly advantageous for slow-speed operations requiring close separations and high raking capacities.   Adjustable spiral speeds:   Recommended speed of operation given in peripheral MPM is an individual consideration for each ore, and is governed by size, shape and gravity of particle, angle of repose of raking load and desired mesh of separation. Peripheral speeds between 6 and 60 meters per minute are available.   Pool depth:   Choice of pool depth is directly related to effectiveness of pool area. Series 90 units are employed for coarse separations on down to 212 micron (65 mesh); Series 125 units are employed for separations between 300 and 106 micron (48 and 150 mesh); Series 150 units are employed for separations of 150 micron (100 mesh) and finer.   Lifting device:   Lifting device eliminates necessity of draining tank during shutdowns. Classifier may be quickly put in operation after shutdown with tank fully sanded. Hydraulic-type standard on all units 1.2 m in diameter and larger. Fast action hand wheel-operated screw- type lift standard on 1.05 m and smaller.   Main Features   Low Initial Cost. Low Operating and Maintenance Cost. Adjustable Flexible Lifting Device.
