Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

The application range of spiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing classifiers …

Now, the common classifiers in mineral processing plant are mainly mechanical classifier and hydrocyclone. Among them,mechanical classifier can be divided into spiral classifier, rake classifier,tank classifier and other types. With the development of classification operation, rake classifier is already replaced by spiral classifier, tank ...

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 & …

Spiral Diameter: DMP has the wide range of Spiral diameters to establish a correct balance between overflow and Raking capacity. Spiral Configuration: DMP Classifiers are provided with Triple start spirals giving maximum agitation and greater raking capacity. The main advantage being slow operating speed giving close separation and high raking.

The spiral classifier is based on the principle that the size of the solid particles and the specific gravity are different, so the sedimentation speed in the liquid is different. It is a kind of grading equipment that is pushed up by the screw and discharged to the top for mechanical grading. It can grade the powder in the mill for filtration ...
