Silica Roll Compactor

The machine operates on a continuous dry granulation principle. Fine silica powder is fed evenly through a vertical or auger feeder into the compaction zone between two counter-rotating rollers under high pressure. This forms solid ribbons or flakes. The compacted material is then milled into uniform granules of the desired size. The process increases density while minimizing fines and preserving material purity without using moisture or heat.

• Capacity: Scalable output from lab-scale (~50 kg/hour) to industrial-scale (up to 18 tons/hour)
• Roller System: Counter-rotating rollers with adjustable pressure, speed, and floating gap control
• Construction: Robust design with GMP-compliant contact parts (typically SS 304/316)
• Key Features: Adjustable roller diameter & speed, high-pressure compaction, integrated granulation/milling stage, and suitability for various silica grades (food, pharma, electronics, agriculture)
• Custom models available with voltage adaptations as per customer requirements.

• Effectively handles low-density, difficult-to-process powders like precipitated silica
• Dry granulation process – no binders, liquids, or drying required
• Improves bulk density, flowability, and handling while reducing volume for storage & transport
• Produces uniform, high-quality granules with minimal fines and dust
• Robust, energy-efficient design with safety features, scalability, and lower operational costs compared to wet methods.

The Silica Roll Compactor is designed for easy cleaning and maintenance, especially important for frequent product changeovers in regulated industries. Smooth stainless steel contact parts, accessible rollers, and modular construction allow quick disassembly and thorough cleaning. The dry process inherently reduces residue buildup, supporting GMP compliance and minimizing downtime.
