Product Introduction

Core Value Proposition

As China's leading pin mill pulverizer manufacturer with Swiss technology heritage, we deliver industry-leading screenless, high-speed pin mill grinding solutions for ultra-fine uniform processing. Our premium pin mill grinder & pin mill machine achieves a finest discharge size down to D90 10μm, with single/dual rotor configurations available. We offer free material testing to validate equipment performance, with full custom solutions tailored to your production needs.

How Our Pin Mill Grinding Machine Works

Our pin mill adopts a pin disc counter-impact crushing structure, with high-efficiency high-speed impact + shear collision mechanism:

1. Materials enter the crushing zone between rotor and stator pin discs via the feed hopper, driven by centrifugal force.
2. The rotor runs at up to 24,000 rpm, creating intensive relative motion with the fixed stator to repeatedly impact, shear and grind materials.
3. Particle size is precisely controlled via rotor speed, pin disc clearance and feed rate; zero screen clogging with our screenless design, and unique air-cooled structure minimizes temperature rise for heat-sensitive materials.
