Size Reduction Services – Precision Particle Processing with Hosokawa

At Hosokawa Custom Processing Services, our size reduction services are designed to deliver consistent, high-quality particle sizes across a wide range of materials. With multiple specialized systems, including Jet Milling, Air Classification Milling, Attrition Milling, Granulation, and Hammer & Screen Milling, we provide customized solutions to meet the unique specifications of each project.

Jet Milling – Ultra-Fine Particle Processing

Our Alpine AFG Jet Mill Systems are ideal for ultra-fine size reduction of materials up to a Moh’s hardness of 10. Utilizing compressed gas, particles collide at high velocities for precision milling down to D99 < 10 microns. Equipped with dynamic air classifiers, our jet milling systems are perfect for applications requiring tight particle size distribution and minimal contamination, such as:

Tungsten Carbide: 95% < 5 microns
Rare Earths: D50 = 1-2 microns
Glass and PPS Polymers: D50 around 20 microns

Air Classification Milling – Controlled Particle Size Distribution

Our Mikro ACM® Air Classifying Mills offer efficient size reduction for materials with a Mohs hardness of up to 4, achieving particle sizes down to D97 < 20 µm. The system’s internal classifier retains particles until they meet specific size requirements, making it ideal for:

Polymers: 99% < 75 microns
Coke: D50 = 20-22 microns
Graphite: 90% < 200 mesh (75 microns)

Attrition Milling – Precision Cutting for Soft and Heat-Sensitive Materials

Our Attrition Milling Systems use high-speed shearing for fine size reduction of plastics, polymers, and fibrous materials without the need for liquid nitrogen or conditioned air. Capable of achieving D90 = 100 µm, this system is perfect for sensitive materials such as:

Polypropylene (PP): 97% < 297 μm
Polycarbonate (PC): 97% < 297 μm
Polyetherketone (PEEK): 99% < 74 μm

Granulation – High-Volume Material Recovery

Our Heavy-Duty Granulation Systems are designed for continuous, high-capacity size reduction and material recovery. With rigid construction and precise knife settings, these systems efficiently handle challenging materials, making them suitable for plastic recycling, fiber, film, purgings, wire, cable, and more. These systems can granulate materials to sizes as fine as 0.250 inches for:

HDPE and PET Bottles
Polymer-based Materials

Hammer & Screen Milling – Flexible Impact Milling

Our Mikro Pulverizer® Hammer & Screen Mills provide efficient mechanical impact milling for continuous size reduction of materials with a Mohs hardness under 4. Capable of achieving D90 = 45 microns, these systems are ideal for a variety of applications requiring flexible, controlled grinding:

Soft to Medium-Hard Materials
Fine Particle Size Control
