LEADING 200 kg Dry Granulator is a production roll-compaction dry granulator with a capacity of 200 kg, manufactured by Nanjing Linghang Pharmaceutical Machinery Co., Ltd. Dry powder is compacted between two rollers and the resulting sheet is milled into uniform granules, so the powder is densified and granulated without any binder, water or drying stage. Typical materials for this configuration: pharmaceutical, nutraceutical and fine chemical powders.
Nanjing Linghang Pharmaceutical Machinery Co., Ltd specialises in roll-compaction dry granulation equipment for the pharmaceutical, nutraceutical, chemical, battery-material and food industries. Machines are designed to GMP requirements and are exported worldwide.
Key Features
- Binder-free dry granulation - dry powder is fed by screw into the rollers and compacted into a sheet under stable hydraulic pressure, then milled and granulated through a rotary cage. No binder, no water and no drying step are required.
- Roller compaction with water-cooled rolls - the rolls are made of special wear-resistant material with internal water circulation cooling, so heat-sensitive products stay within a safe temperature window.
- Stable hydraulic system - an imported hydraulic power pack delivers constant linear pressure with no leakage; the double-acting cylinder keeps the roll gap and the flake thickness uniform.
- Independent variable-frequency drives for the feeding screw, the rollers and the granulating rotor, so throughput rate and granule quality can be tuned independently.
- Particle size by screen selection - granules are classified on a vibrating screen; the gap between rotor and screen is adjustable through an eccentric shaft without opening the guard, giving a finished granule range of roughly 0.1-2 mm.
- PLC + HMI control - automatic and manual modes, real-time process display and storage of up to 100 recipes for fast product changeover.
- GMP-compliant construction - all product-contact parts in SUS304 stainless steel, internal surfaces polished to Ra < 0.4 um, quick-release product-contact assemblies and no dead corners; the lubrication system is isolated so no lubricant can reach the product.
- Containment and explosion-proof options - negative-pressure enclosures, OEB high-containment designs and Exd IIB T4 Gb explosion-proof electricals are available for potent compounds and combustible powders.
- Safety and reliability - automatic reverse rotation on material blockage, mechanical locking guards on exposed rotating parts, integrated start / stop / emergency-stop control and interlocked safety switches.
- Complete delivery - main unit plus chiller (where applicable), screens in the required mesh sizes, and full documentation including operating manual, maintenance manual, material certificates, qualification certificate and spare parts list.
