High-Efficiency Pharmaceutical Dry Granulation Roller Compactor | LG Series by Guibao Group

As a leading Chinese manufacturer of pharmaceutical dry granulators and roller compactors, Guibao Group's LG series delivers High Granulation Rate, 100% Leak-Proof sealing, 5-min fast assembly/disassembly, and smart dry granulation systems for the pharma industry. Whether you need a laboratory roller compactor for R&D or an industrial roll compactor for large-scale tablet manufacturing, our dry granulation equipment offers superior performance and reliability.

1. High Granulation Rate & High Output Pharmaceutical Dry Granulators

• Our dry granulation roller compactors deliver over 10% higher output than equivalent models from other manufacturers, with large-capacity LG240 and LG360 roll compactor models available. The easy-to-disassemble and clean LG240 pharma roll compactor is widely adopted by numerous renowned pharmaceutical enterprises across China.
• For TCM formula granules production via roller compaction granulation: the machine achieves a feed rate of ≥300 kg/h, with qualified granules (12–35 mesh) output of ≥200 kg/h.
• Welded woven wire mesh screen ensures a primary granulation rate of ≥65% for 10–40 mesh granules, optimizing the dry granulation process for consistent results.

2. 100% Leak-Proof Pharma Roller Compactors for Operator & Drug Safety

Ensuring drug production safety is the core priority in the design and manufacturing of our pharmaceutical roller compactor machines. Guibao LG series dry granulators feature elaborate, industry-leading designs to fully prevent powder, water, and oil leakage throughout the dry compaction process.

• Foamed silicone rubber strip with 3 adjustable bolts at the feed hopper and barrel joint: guarantees zero powder leakage even during vacuum feeding and backflushing of the dry granulator machine.
• Special labyrinth seal structure at the feeder end cover and screw contact area: fits tightly with rotating parts while maintaining flexibility, delivering 3x longer service life than ordinary seals for pharma roller compaction equipment.
• Hollow silicone rubber seal at the front hood door and front panel joint: high compressibility and elasticity, tightly adheres to the grinder-finished frame panel for reliable sealing during the roller compaction process.
• Built-in negative pressure water pump chiller, combined with 3-layer seal rings on the compression roller main shaft: greatly reduces cavity pressure and completely eliminates water leakage risks for our roll compactors.
• Customized motors for the granulating and feeding systems of our dry granulation machines: rotating parts are directly mounted on the gear motor shaft without extra bearings, fully avoiding lubricating oil leakage caused by damaged skeleton oil seals.

3. 5-Min Fast Assembly/Disassembly Dry Granulator Machines

• The main unit of our LG series dry granulators can be fully disassembled in less than 5 minutes, and reassembled in less than 10 minutes, greatly reducing downtime for cleaning and maintenance.
• Minimized fastener design: only 16 frequently used fasteners (at least 10 fewer than competing roller compactor machines), with uniform specifications requiring fewer types of wrenches for operation.
• Optimized tensioning, pressing, and baffle structures for our roll compaction granulation equipment: fewer components, convenient installation, fewer wearing parts, and lower long-term operating costs.
• Fixed gap between the granulating knife and granulating screen frame: production can be started immediately after installation without additional adjustment, significantly shortening production preparation time for the dry granulation process.

4. Smart Dry Granulation System with Real-Time Observation

Our LG series pharmaceutical roller compactor features a baffle-free design at the compression roller slab outlet, paired with a fully transparent front hood, enabling operators to conduct real-time visual monitoring of the entire roller compaction and dry granulation process without obstruction. The integrated electrical control system forms a smart dry granulation system for easy operation and monitoring.

5. Advanced Anti-Bridging Vacuum Feeder for Fully Automated Dry Granulation

Conventional vacuum feeders for powder roller compactor equipment commonly face two critical issues: materials with poor flowability tend to bridge inside the feeder during vacuum feeding, and the respirator is prone to clogging after 3-4 hours of continuous operation. Guibao's matched vacuum feeder for our dry granulators is equipped with a professional anti-bridging device and respirator anti-clogging device, effectively eliminating material bridging and respirator clogging issues to realize stable, fully automated dry granulation production.

6. Integrated Electrical Control System for Compact & Easy-to-Install Dry Granulator Machines

The electrical control system of our LG series roll compactors adopts an integrated layout with the main unit, delivering a smaller overall footprint, faster on-site installation, and simpler commissioning for pharmaceutical production lines.
