The hammer mills 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.

Available in virtually indestructible fabricate or stainless steel, Classifier Milling System’s hammer mills are available in custom sizes up to 200HP. CMS warehousing maintains stocks of screens, liners, and hammers.

Hammer Mill Facts:

  • Rugged, requiring minimal maintenance when compared to most grinding systems
  • Single access point for easy 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
