The Step Screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other Fine Screen technology. Step Screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. For the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).

Rotary pumps use a variety of means to generate flow. A pair of gears with many teeth (external to the gear and called an external gear pump) in gear pumps or a few lobes in lobe pumps is demonstrated in Fig. 23.2.Internal gear pumps use a gear within a gear design; internal means the teeth of one gear are on the inside, projecting inward. Gear pumps are useful for …

Rotary breakers are highly reliable, and are not susceptible to damage by hard rock or tramp iron. The screen plates in a rotary breaker are extremely long-lived, commonly lasting 10 years or more depending on the abrasiveness of the coal. Some breakers are designed so that the screen plates can be interchanged.

particle is removed (d=0), the equation equals the percent open area of a square mesh wire screen÷100. Thus if p is proportional to capacity, in a square mesh wire screen capacity must be proportional to the percent open area, a relationship that is made use of later in deriving the capacity correction factor F (Page 22) for the ratio L/t.
