Introduction
WANROOETECH stainless steel pulverizers deliver contamination-free micronization for industries where purity is non-negotiable—food, pharmaceuticals, chemicals, and specialty polymers. Engineered entirely from 304/316L stainless steel, these systems eliminate corrosion risks, prevent material adhesion, and meet GMP/FDA standards while processing materials from spices to APIs at throughputs up to 3,000 kg/h.
Application Areas
Stainless steel pulverizers process food-grade materials including spices, grains, sugar, nuts, and dehydrated products; pharmaceutical ingredients such as APIs, herbal powders, and nutraceuticals; chemical products including dyes, pigments, and salts; and polymer compounds like masterbatch and color concentrates across industries requiring contamination-free, corrosion-resistant grinding.
Working principle
Material enters the grinding chamber and accelerates via centrifugal force between a stationary disc and a high-speed rotating disc (up to 6,000 rpm). Intense impact, shear, and friction reduce particles to target size, controlled precisely by adjustable disc gap settings—no screens needed. Pneumatic discharge ensures continuous, clog-free operation. For fibrous or heat-sensitive materials, dual water/air cooling protects product integrity and extends bearing life.

Core Advantages
Zero Contamination Risk — Full SS304/316L contact surfaces prevent rust and cross-contamination. Mirror-polished finishes eliminate material buildup, supporting CIP/SIP protocols.
Precision Control — Disc gap adjustment delivers consistent particle size distribution from 20 to 320 mesh without component changes. SKF bearings and Siemens motors ensure stable, long-term operation.
Thermal Protection — Integrated water jackets and forced-air cooling maintain optimal chamber temperatures, preventing degradation of heat-sensitive APIs, spices, and polymers.
Intelligent Operation — PLC-based controls with touchscreen interface monitor temperature, vibration, and load in real-time. Automatic overload protection and emergency stop systems safeguard both product and equipment.
Sealed Processing — Dust-tight chambers with integrated cyclone separators and pulse-jet dust collectors maintain workplace cleanliness and recover valuable product.
