If the shaker table tailings are too coarse, they can be classified with a spiral classifier, and the over-sized discharge returned to the ball mill for additional grinding. When concentrating gold ore, our shaker table will get a high percentage of the free gold >325 mesh, even down to less than 400 mesh, equaling or out-performing any table ...
Classification. The purpose of classification is to control the size of the material being fed to the dissolving or agitation circuit. The discharge from the ball mill flows into the classifier where it is split into a sand and slime portion; the sand particles being returned by mechanical means to the feed end of the ball mill, while the material of …

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …
Gold classifiers, also called sieves or screens, go hand in hand with a gold pan. Designed to fit on the top of 5 gallon plastic buckets used by most prospectors, and over most gold pans, the classifier's job is to screen …

The speed of mills depends upon their diameter; a ball-mill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times. Tube-mills run at a revolution or two faster (see Fig. 117). Some ores require much finer grinding than others to liberate the minerals, and this increases the milling cost. Ball Mill Product Classifying
A large access door on these mills allows for quick inspection and/or cleaning of the main classifier mill rotor as well as the air classifier rotor. CLM Air Classifying Mill General Dimensions.
