Slurry concentration, Ore feeding amount & Uniformity When the concentration of the slurry is constant, if the amount of ore fed into the classifier increases, the flow rate of the slurry will also increase, thus making the overflow product particle size coarser. As the ore volume decreases, the particle size of the overflow product becomes finer, and at the same time, the …
The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.
Further research to study the iron-ore slime (fines) beneficiation is ongoing. The novel closed spiral classifier creates around 80–180 G-force. Our CFD study estimates that the shear rates in the equipment wil be of the order of 10 3 s −1, whereas hydrocyclones will generate around 10 4 s −1 at similar process conditions . Thus, it may ...
Spiral classifiers are widely used in dressing plants to form a closed-circuit cycle with ball mills to separate ore sands, or to classify ore sand and fine mud in gravity beneficiation plants, and to classify ore pulp in metal beneficiation processes, and to wash ore desliming, dehydration and other operations during operation.
