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.Web

Many other evaluation metrics have been developed. It is important to remember that each is simply a different way of summarizing the confusion matrix. Here are some metrics you'll likely come across: true positive rate = TP/ (TP+FN) = 1 − false negative rate. false positive rate = FP/ (FP+TN) = 1 − true negative rate.Web

Nesans Spiral Classifier consists of an open trough with a chute provided for the input feed material. Before being fed into the spiral classifier, the dust from the screen is mixed with water and it is carried to the input chute through a slurry pump. The inlet flow is evenly distributed across the surface area of the spirals.Web

The spiral classifier works by virtue of the principle that the size and specific gravity of solid particles are different, so the sedimentation rate in liquid is different. Fine ore particles float in the water and overflow, while coarse ore particles sink at the bottom of the tank and are discharged by spiraling upward to perform mechanical ...Web

It works 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 ball mill grinding again, to form a closed-loop. The 200mesh slurry will be pumped to a gravity separation machine, spiral chute, and shaking table. The spiral chute is for ...Web
