Problem
- The biomass and renewable energy company required a robust system to process 3000 kg/hr of saw dust for fuel production.
- The saw dust had approximately 50% input moisture and needed to be dried to around 12% for suitable biomass fuel application.
- The client required uniform drying performance, reliable mechanical construction, efficient combustion, proper dust separation, and automated temperature monitoring.
- The system also needed stable continuous operation under industrial fuel-processing conditions.
Proposed Solution
- Gem Drytech supplied and commissioned a complete rotary dryer system engineered for high-capacity saw dust drying.
- The system included an 1800 mm diameter x 12000 mm long rotary dryer with 10 mm shell thickness, designed for 3000 kg/hr input capacity.
- A firewood fired brick furnace with refractory lining was supplied for controlled heat generation.
- Cyclone separator system with interconnecting ducting was provided for fines separation and emission control.
- A control panel with temperature monitoring and motor controls enabled structured operation and process supervision.
Result
- The system achieved the designed input capacity of 3000 kg/hr.
- Moisture was reduced from approximately 50% to around 12%.
- The furnace, cyclone separator, ducting, and control systems functioned properly during installation and performance trials.
- The plant achieved stable and continuous operation with consistent drying performance.
- The system is operating satisfactorily and meeting the agreed technical specifications.
Conclusion
- This project demonstrates Gem Drytech’s capability to deliver high-capacity rotary drying systems for biomass and renewable energy applications, combining thermal engineering, mechanical durability, fuel flexibility, and controlled moisture reduction.
Applicability
- Well suited for saw dust, wood chips, biomass residues, bagasse, agro-waste, husk, and similar high-moisture fuel-processing applications where consistent final moisture and reliable continuous operation are required.
