Theory: In centrifugal filtration, a perforated basket is installed inside a centrifuge machine, and connected to an external rotation supply. Changing the rotational speed or angular velocity ω of the vessel, which can be converted to G-force using the following relationship, varies the centrifugal force [1,12]: g r G ω2 =, [1]

2.1. Disc Mills. Disc mills are probably the most ancient type of grinding equipment. Their principle of action is as follows: the material passes between two rotating discs, causing friction of particles against the discs and grinding (Figure 1 a).Mills with a variable gap between the discs and discs with notches are used to increase the milling …

Wheat received at the mill contains weeds, seeds, chaff, and other foreign material. Strong drafts of air from the aspirator remove lighter impurities. The disc separator removes barley, oats, and other foreign materials. From there, the wheat goes to the scourers in which it is driven vigorously against perforated steel casings by metal beaters.

43.1 Introduction. Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, i.e. compression, impact and shear.

A colloid mill is used in the size reduction of solids and droplet present in suspension or emulsion (Fig. 6.16). A colloid mill consists of a rotating cone (rotor), a static cone (stator), and a feeding unit. The size reduction mainly takes place due to the shearing action in the narrow gap between the rotor and stator.
