The roller of the briquetting machine is the core component responsible for high-pressure molding of powdery materials, forming them into spherical or block shapes. Its design and performance directly affect the efficiency of the briquetting machine and product quality, commonly used in metallurgy, chemical, energy, and other industries.
Roller Classification
- High-pressure roller: Suitable for high-density materials such as metal ore powder, dry pressing (without binder), with higher pressure ranging from 9t/cm to 20t/cm.
- Medium-pressure roller: Suitable for general materials such as coal powder and coke powder, wet pressing (with binder), with lower pressure ranging from 3t/cm to 6t/cm.
Specifications
- Diameter range: 360mm to 1400mm.
- Width range: 250mm to 900mm.
- Total pressure: 150 tons to 1000 tons.
- Main motor power: 7.5kW to 800kW.
Application Scope
- Metallurgical industry: Pressing metal powders such as iron powder and aluminum powder.
- Energy sector: Forming coal powder and coke powder for power generation or fuel.
- Chemical industry: Briquetting powdery materials such as catalysts and fertilizers.
Key Components
- High wear-resistant roller surface: Made of materials like 65Mn, 9Cr2Mn, GCr15SiMn, with roller surface hardness HRC55-62 to ensure wear resistance and extend service life.
- Main shaft made of 42CrMo alloy steel forging, high strength and impact resistance.
- Assembly and debugging: Installation of hydraulic system and thin oil lubrication system to ensure smooth operation.
- Hydraulic adjustment: Real-time pressure adjustment to meet different material requirements.
- Synchronous transmission: Dual output parallel shaft synchronous gearbox ensures synchronous operation of two rollers, improving molding quality.
Outstanding Advantages
- Efficient molding: High line pressure and optimized structure improve balling rate and productivity.
- Safe and reliable: Hydraulic overload protection prevents damage to the pressing shaft by hard objects.
- Energy-saving and environmentally friendly: Pre-pressing device reduces main motor load and lowers energy consumption.
- Easy maintenance: Modular design facilitates disassembly and repair.
