Straw pellet press RWPR

for sawdustfor woodwork waste

Overview
The Bühler pellet mill RWPR is engineered to withstand the most demanding pelleting conditions, from biomass and wood to sunflower hulls, delivering maximum throughput for industrial and household pellet production.

Key benefits

• Handles high pressures for flexible production: processes finely ground wood, straw and other biomass particles as well as sunflower hulls.
• Operator-friendly: clear user guidance with low maintenance and cleaning needs.
• High performance: maximizes throughput on challenging raw materials.

Highlight features

• Integrated machine control monitors key process parameters such as raw material moisture and temperature.
• Conditioning with water and steam to activate natural binders in the raw material.
• Dies engineered for specific raw materials to ensure consistent pellet quality and throughput.

Safety
Rugged paneling covers moving parts and is key-locked for controlled access; the control system pneumatically disengages press rolls and alerts the operator if abnormal conditions are detected.

Production flexibility
Pneumatically operated inlet bypass releases feeding overloads automatically to prevent time-consuming stoppages.

Other features & options

• Automatic lubrication system with large grease reservoir for continuous operation.
• Optional on-machine mounting hoist to speed up press roll and die changes.

Application possibilities

• Biomass and wood pelleting
• Sunflower hull pelleting
• Processing of finely ground biomass, straw and oilseeds
• Industrial and household pellet production

Services and training
Bühler offers spare and wear parts, roll and die service, consulting and training to maximize lifecycle and performance.
