The design of these classifiers (rake, spiral, screw) have inherent problems, First they are very susceptible to wear, caused by the scrubbing action of the ore, that plus all of the mechanical moving parts create many worn areas to contend with. The other problem that these classifiers have is that they are easily over loaded.
The rake classifier. It is a mechanical classifier utilising rakes. The rakes are actuated by an eccentric motion to dip into the settled material and 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 The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated; the settled material is thus slowly moved up the incline ...
At the design flow condition of 1.5 lpm aerosol (or 16.5 lpm aerosol high inlet flow case) and 15.0 lpm sheath flow rates, the measurable size range is from 3–50 nm.
Linear Classifiers. Sergios Theodoridis, Konstantinos Koutroumbas, in Pattern Recognition (Fourth Edition), 2009. 3.1 Introduction. Our major concern in Chapter 2 was to design classifiers based on probability density or probability functions. In some cases, we saw that the resulting classifiers were equivalent to a set of linear discriminant functions.

In the rake classifier, which consists of a shallow rectangular tank inclined to the horizontal, ... In this section, the general design of the hydrocyclone and its application in the grading of solid particles, or their separation from a liquid, is considered and then the special features required in hydrocyclones required for the separation ...
This work provides a comparison between the most commonly used classification equipment in the treatment of minerals - hydrocyclones and spiral classifiers - considering their applications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lot of their importance due to the development of cyclones. This trend, however, is now being reversed, …

Coghill and deVaney (1938) also conducted experiments in a pilot plant ball mill closed circuited with a rake classifier over a wide range of circulating load ratios. They noted that, "It held true that the percentage of decrease in mill capacity was almost identical with the percentage of finished material in the composite feed.
