Hammer Mill

Hammer Mill

The hammer mill is a rugged high-speed industrial impact mill (turbo mill) engineered to operate in high-volume production environments requiring continuous particle size reduction, so commonly used in industrial chemicals, food, and pharmaceutical industries.

How Does a Hammer Mill Work?

Particle size reduction of feed materials by hammer mills occurs in three actions: repeated high-speed impact from hardened steel rotating hammers, materials colliding with the grinding chamber/liner wall, and high-speed particle-to-particle collision | impact and shearing |. Screens, set at a specified cut point, retain coarse particles for further grinding while allowing product sizes below the cut point to pass and exit the mill. Achieving the target particle sizing is a function of rotor speed, feed rate, hit resistance, clearance between grinding plates and hammers, and screen size.

Hammer Mill Facts:

• Rugged, requiring minimal maintenance when compared to most grinding systems
• Single access point for maintenance, cleaning, and service
• Accommodates a wide range of particle sizes (typically capable of milling down to 45 µm d90)
• A leading mill for size reduction of brittle/friable materials
• Durable housing and a unique lightweight rotor design
