The performance measures in Table 2, Table 3, are presenting the machine learning tools to classify the test data of spiral drawing, with binary classification of healthy and patient classes.These measures demonstrate that though there is limited dataset of spiral drawings (mix of static and dynamic), the patterns can be evaluated and classified.
Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.
The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and …

Training an image classifier. We will do the following steps in order: Load and normalize the R10 training and test datasets using torchvision. Define a Convolutional Neural Network. Define a loss function. Train the network on the training data. Test the network on the test data. 1. Load and normalize R10.
Because users' needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user's classification requirements. Spiral diameters (0.3 m to 2.25 m): Important in establishing a correct balance between overflow and raking capacity.

The Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with , 125%, and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. The spiral classifier is one of the size-classifying equipment for the mining industry.
In the post we use tree, boosting and K nearest neighbor on spiral data. KNN is most intuitive one, it make the classification according to a given point's neighbors. So, spiral data would not "break the neighbor rule" …
Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of …
The spiral classifier is widely applied for the following fields: combine with ball grinder into closed circulation for ore-sand separation in the ore separation plant; classify ore sand and fine sludge in gravity ore separation plant; classify the grain of ore pulp at the metal ore separation process; and remove sludge/water at the ore separation process.
When we classify a test example, we assign it to the class with the highest corresponding value in the output vector. 3.3 Ensemble methods. An ensemble of classifiers consists of a set of classifiers whose individual decisions are combined in some way, normally by voting. Ensembles often yield better results than individual classifiers.

The data set is well balanced by design, it has 1 200 data points and 3 classes (400 per class). A linear classifier would be very bad in classifying this data set as it is impossible to divide data points by lines as you can see in the image below. It is a 33.33 % probabilty (400/1200) to classify a data point correctly and this is our ...
The spiral classifier is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding …

The rotation speed of the commonly used spiral classifier is. To obtain coarse overflow, the speed of the spiral with a diameter of 2 m should not exceed 6 r/min, and with a diameter of 1 m or more should be controlled at 2-8 r/min.
