Introduction of High Weir Spiral Classifier Equipment, Mining Classifier
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.
Spiral Classifiers are mechanically the devices are powerfully built, and functionally they are versatile and flexible.
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.


Details of High Weir Spiral Classifier Equipment, Mining Classifier
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.

Working Principle of High Weir Spiral Classifier Equipment, Mining Classifier   

Spiral classifier, working with ore mills to form close circulation in the concentrating plant, whose classification process depends on the sedimentation velocity of the particles. Its external appearance is a rectangular oblique chute, whose bottom is semi-circular; the inclination angle of the bottom of the chute is from 120 to 18.50.There is 1 or 2 vertical axles installed in the chute, spiral blades are installed along the axle one after another. With the help of the drive motor on the top, the whole machine can drive the screw shafts to rotate. If there are two spiral axles in the chute, all of the spiral blades rotate outwards when the machine is viewed from the top. The slurry, fed from the flank of the chute, form classification of sedimentation at the bottom of the chute. Coarse particles dip into the bottom of the chute, and then they will be pushed to the top by the spiral and discharged. During the transportation process, the coarse particles dehydrate themselves. The fine particles, which do not have enough time to dip into the bottom of the chute, are carried by the ore pulp flow through the surface and discharged from the overflow weir. There is lifting equipment on the upper beam of the frame, which is used to adjust the distance between the spiral blades and the chute bottom and raise the spiral axle when the machine stops working, in case that the ores deposit and bury the spiral blades to damage the axles and blades when the machine starts working again.

According to the height of the surface of the liquid classification, the machines can be pided into high weir type and immersed weir type. The overflow weir of the high weir type spiral classifier; is higher than the center of the spiral axle at the bottom and lower than the top of the spiral blades. As the surface of the liquid classification is not very long, the liquid surface can feel the mixing of the spiral blades, and then this kind of machine can be used for the classification of coarse particles, whose classification granule is more than 0.15MM. The whole spiral blades of the immersed weir type are immersed in the flooding level, the area of the classification is large and stable, which is suitable for the classification of the fine particles, the classification granule of which is less than 0.15MM. It has high productivity. Besides, there is one kind of low weir type of spiral classifier, whose surface of the liquid classification is lower than the spiral bearing. The area of the liquid surface is small,but the machine can mix strongly. It is mainly used in the washing of the ores with mud.
