7.5kw Hammer Mill

Introduction

A 7.5kW hammer mill is a compact yet efficient grinding equipment designed for processing granular materials, with exceptional performance in handling grains such as corn, wheat, barley, and rice. Its moderate power output balances productivity and energy efficiency, making it ideal for small to medium - scale operations where precise particle size reduction of grains is required.

Working Principle

The 7.5kW hammer mill operates on the principle of high - speed impact grinding. Inside the grinding chamber, a rotor equipped with multiple hardened steel hammers rotates at high speed (typically 2,800 - 3,600 rpm) driven by a 7.5kW motor. When grains like corn are fed into the chamber, they are instantly struck and shattered by the rotating hammers. The shattered particles are then forced through a screen (with adjustable mesh sizes, usually 1 - 10mm) at the bottom of the chamber, ensuring uniform particle size. Unprocessed larger particles remain in the chamber for further grinding until they pass through the screen.

Key Advantages

-Compact Design: Small footprint, easy to install in workshops, farms, or small factories without occupying excessive space.

-Adjustable Fineness: By replacing screens with different mesh sizes, it can produce grain powders of various consistencies—from coarse grits (for animal feed) to fine flours (for food processing).

-Energy Efficiency: The 7.5kW motor provides sufficient power for continuous grinding of grains while minimizing energy consumption, suitable for long - term operation.

-Easy Maintenance: Removable screens and hammers simplify cleaning and replacement, reducing downtime for upkeep.
