Product Introduction

High-Efficiency Pin Mill for Fine Grinding

Name: PM Series Single-power Pin Mill
SKU: 0

Guibao Group – China's No. 1 Manufacturer of Pin Mills Since 1984

Advanced precision grinding for pharmaceuticals, food, and fine chemicals.

Driven by the screw, materials enter the milling chamber of the pin mill at a constant speed. The annular pin forests of the high-speed rotating rotor and stationary stator alternately buckle. As the rotor rotates at high speed (linear speed up to 250 m/s), it generates strong centrifugal force. Materials pass through the pin forests and collide repeatedly (material-to-material and material-to-pin collision), achieving the milling effect. The pin mill is screen-free, and the minimum milling particle size can reach 5 microns (D90).

Key Applications & Processing Materials

Guibao Pin Mill is designed for precision size reduction across sensitive and demanding industries, ensuring high purity and controlled particle size (down to D₉₇ < 5μm).

? Pharmaceutical Raw Materials: Active Pharmaceutical Ingredients (APIs), Excipients, and Intermediates.
? Food & Beverages: Processing Sugar, Salt, Spices, Herbs, and Food Additives.
? Fine Chemicals: Handling Dyes, Pigments, Resins, Fertilizers, and Specialty Powders.

Product Features of the Pin Mill

Feature	Benefit / Solves Pain Point
Screen-free design:	No clogging, lower maintenance costs, high rotation speed, and adjustable speed—optimizing adaptability to different materials.
Ultra-fine milling capability:	The finest milling particle size can reach 5 microns (D90), highlighting the pin mill's ultra-fine milling capability.
Effective temperature control:	Adopts circumferential water cooling + air seal air cooling—effectively controlling temperature rise during high-speed operation.
Secure material handling:	Multiple seals (lip seal and positive pressure seal) to prevent material leakage and ensure processing safety.
