The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper.

The hammer mill's functioning principle is straightforward. Fig. 2.2 illustrates the principle (a). All that is required is the selection of a suitable engine, crushing hammers/knives, and the material to be crushed. It works on the basis of impact between the rotor's fast-moving hammers and the stationary powder bed.

SCFM refers to "standard cubic feet per minute" or the given flow rate of air at standard room temperature and pressure. Standard air flow is the baseline required flow; depending on your operating conditions (i.e. differing pressure and temperature) this tool allows you to convert the required SCFM, to the actual flow or ACFM that you will read from your instruments.
