Classification

Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow . The spirals impede the ...

Spiral classifier or hydrocyclone

A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

CS231n Convolutional Neural Networks for Visual Recognition

The parameters of the linear classifier consist of a weight matrix W and a bias vector b for each class. Lets first initialize these parameters to be random numbers: # initialize parameters randomly W = 0.01 * np.random.randn(D,K) b = np.zeros( (1,K)) Recall that we D = 2 is the dimensionality and K = 3 is the number of classes.

It is obvious that the floor area of hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the hydrocyclone covers an area of only l/30 to l/50 to the spiral classifier. The equipment floor area requirement also limits the application of the spiral classifier to a certain extent. 3. Classification Efficiency.

Spiral Classifier, Dewatering Screw

This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values. Many locations don't have a ready source of water, so when used as a ...
