Calculation Of Horizontal Shaft Hammer Mill

Hammermill - 3D CAD Models & 2D Drawings

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.

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.
