NARA Pin mill
Ultra Fine milling. Small Footprint.
The Nara Pin Mill features a dual-disc pin design, where two interlocking steel discs—studded with pins—rotate at high velocity. This configuration generates high-impact and shear forces to efficiently break down materials into fine, uniform particles. Its compact structure maximizes performance while minimizing footprint, making it an ideal solution for space-constrained facilities.
Performance Highlights
- Ultra-Fine Grinding: Capable of delivering particle sizes below 40 μm with exceptional uniformity.
- Efficient Footprint: Compact design reduces floor space usage and simplifies integration.
- Heat Management Options: Features available for cryogenic or cooled milling, ideal for heat-sensitive materials
- Versatility: Effective on a wide range of substances, including dry powders, moist slurries, and heat-sensitive materials.
Design & Maintenance
-
Durable Construction: Rugged housing with easy-access design enables quick maintenance.
-
Replaceable Components: Interchangeable pin discs and sealing systems reduce downtime.
-
Variable Speed Control: VFD-driven motors allow adjustable rotor speed for product optimization.
-
Customized Configurations: Stainless steel, flame-proof motors, integrated feeders, and cooling systems available depending on application requirements
