Dry Powder Briquette Machine

Dry powder coal briquette machine (high-pressure coal briquetting press) is a premier forming solution designed specifically for materials with low moisture or requiring zero binder addition, such as dry coal dust, coke breeze, quicklime powder, and mineral fines. Utilizing an advanced screw-feeding pre-compressor and extra-high-pressure counter-rotating rollers, it forces loose dry powders into dense, high-strength briquettes. The final briquettes feature high purity and excellent thermal stability, turning industrial coal and coke residues into high-value combustible or metallurgical resources without altering their chemical properties.

Features:
 
Advanced binder-free or low-moisture forming under extreme hydraulic pressure.
 
 
Dual-stage compression with a powerful vertical screw pre-feeder.
 
 
Heavy-duty roller sleeves forged from premium wear-resistant alloy steels.
 
 
Intelligent hydraulic pressure system with automated overload protection.
 
 
Customizable roller molds for various briquette shapes (pillow, oval, round).
 
 
High briquetting rate (over 96%) with exceptional final ball hardness.
 
 
Enclosed dust-proof structure ensuring a clean and eco-friendly workspace.

Benefits Features

1. High-pressure binder-free forming for pure final briquettes.
Equipped with a high-tonnage hydraulic station, the machine generates extreme linear pressure to force particles to bond naturally. This eliminates the cost of chemical binders and ensures the final coal or coke briquettes maintain 100% purity with zero additive ash, maximizing their heating value.

2. Forced screw pre-compression for air elimination.
Features a powerful, speed-adjustable vertical screw feeder at the intake. This pre-compresses the fluffy dry powder and forces out trapped air before it enters the rollers, dramatically increasing the density, filling ratio, and initial strength of the briquettes.

3. Premium 9Cr2Mo/65Mn forged rollers with deep hardening.
The roller shells are manufactured from top-grade 9Cr2Mo or 65Mn alloy steel and undergo advanced vacuum quenching heat treatments. This guarantees extreme surface hardness and core toughness, offering an extended service life against highly abrasive dry fines.

4. Intelligent hydraulic system with tramp iron protection.
The advanced hydraulic cylinder system maintains consistent forming pressure. If an unbreakable foreign object (like a steel bolt) enters the chamber, the hydraulic valves instantly release the pressure to let the rollers open safely and reset automatically, protecting the main shafts and bearings.

5. Seamless integration and environmental compliance.
Designed with a fully sealed heavy-duty casing to completely prevent dust leakage during high-pressure processing. It operates with low vibration and can be easily integrated into fully automated, dust-free industrial briquetting production lines.
