In these classifiers the required pool area is balanced with the sand raking capacity of the spiral by the design of the tank. Heavy particles have time to settle at the bottom and the spiral conveyor moves the settled particles upwards along the floor of the trough. Spiral classifiers are used for close circuit grinding.
The spiral classifier mainly has four types of high single screw and double screw, submerged single screw and double screw. It is widely used in concentrators and ball mills to form closed-circuit circulation range split flow ore sand, or used in Gravity beneficiation plants come to classify ore and fine mud, and perform particle size classification of ore pulp in metal …
The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able to pull the course ore backwards further than it can travel forwards, then eventually the bigger particles will be pulled all the way ...
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 also can be called spiral separator, screw classifier or screw separator. Email: vip@zoomjo. Whatsapp: +86 . Tel: +86 . ... Spiral classifiers can grade different particles in ore slurry during the metal beneficiation process as well as deslime and dehydrate in the washing operation.
The document discusses spiral classifiers, which are used in mineral processing to separate ore slurries by particle size. It outlines several key variables that must be balanced for effective classification, including the angle of the inclined bed, speed of the rakes or spirals, slurry density, tonnage throughput, and ore settling rate.
