Rake and spiral classifiers are used for close-circuit grinding. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the ...

It divides spiral classifiers into single-spiral and Duplex Spiral classifiers according to the number of spirals. The classification performance of the two is the same, but the double screw classifier has a larger processing capacity and is suitable for use with large grinding machines.

Spiral classifiers, such as the Alpine Mikroplex design for separation in the superfine region, were developed to partially overcome undesirable boundary layer effects associated with spinning fluids at stationary walls (Rumpf and Leschonski (1967)). Air is introduced tangentially at the periphery into a flat cylindrical space and moves along ...

The ball mill is for grinding 0-20mm to small powder. It works together with the spiral classifier, so the overflow slurry from the classifier is about 80% 200mesh powder. The oversize particle from the classifier will go back to the ball mill grinding again, to form a closed-loop.

The run for Spiral was between 187 to ~300 Epoch, depending. I used Lasso Regularization L1 so I could eliminate coefficients. I decreased the batch size by 1 to keep the output from over fitting. In my second example I added some noise to the data set then upped the L1 to compensate.

It is evident that no linear classifier will be able to do a good job classifying spiral data where the boundary between two classes is a curve. A simple two layer network with RELU activation on the hidden layer automatically learns the decision boundaries and achieves a 99% classification accuracy on such a data set.

if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The formed spiral would also slope inwards towards the supporting cylinder. This is the important angle β of fig.1 and is given by: tanβ = 2(D2-D1) (5 ...

The footprint of a hydrocyclone is significantly smaller than that of a spiral classifier. Usually, the hydrocyclone occupies only 1/30-1/50 of the spiral classifier.
