Building a 2 Layer Network to Classify a Spiral Dataset
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.

Aerodynamic classification in a spiral jet mill
Within a spiral jet mill the size reduction and the classification are accomplished simultaneously in the same volume. Size reduction occurs mainly near the outer walls as a result of particle–wall and particle–particle collisions. The size reduction intensity is defined by the impact velocity or throughput.
An operational model for a spiral classifier
Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough ( Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.
