Hammer mill

It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer), which rotates at high speed inside the chamber.

These radically swinging hammers (from the rotating central shaft) move at a high angular velocity causing brittle fracture of the feed material. Hammer mills crush materials into two (2) stages.

1. Size reduction which occurs by dynamic impact.
2. Sizing which occurs by attrition and shear in the second zone where small clearance exists between the hammer and the screen bar producing a particle range of 15-50 micrometer.

The material is crushed or shattered by the repeated hammer impacts, collisions with the walls of the grinding chamber as well as particle-on-particle impacts. Screens for optimal capacity and excellent grind quality are fitted at the bottom of the mill, which retains coarse materials while allowing the properly sized materials to pass as finished product.

The screens range in size from 1 to 20mm and are easily interchangeable thanks to a quick-change, spring-loaded, shock-absorbent screen carriage.

Note - Anti explosion & design & controls are critical for commercial milling.

Features & Benefits:

• Produces specified top size without the need for a closed-circuit crushing system.
• Produces relatively numerous size distributions with a minimum of fines due to self-classification.
• Has high reduction ratio and high capacity whether used for primary, secondary or tertiary grinding.
• Reasonable energy requirements.
• Brittle materials are best fractured by impact from blunt hammers.
• Capable of grinding many different types of materials.
• The machine is easy to install and operate and its operation is continuous.
