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.
WhatsApp: +86 18838072829Rotor: Rotor is composed of main shaft, hammer frame board, axis pin, hammers, bearing and other parts. It is the main moving element of the mill. It is the main moving element of the mill. The rotating speed of rotor is high; therefore, the assembly must proofed by the balance test before the axis pin and hammers are installed
WhatsApp: +86 18838072829Hammer Mill Working Principle. The hammermill, fundamentally, is a simple mechanism. The "orthodox" machine comprises a boxlike frame, or housing, a centrally disposed, horizontalshaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing.
