Hot Air Furnace

Hot Air Furnace Features & Advantages

Efficiency Improvement: Continuous and stable hot air supply guarantees smooth operation of subsequent grinding and classification processes, reducing frequent shutdown and cleaning caused by material blockage and wall adhesion. It features high heat energy utilization and low energy loss, extending the service life of core components such as grinding rollers and bearings.

Quality Assurance: By precisely controlling hot air temperature, material moisture can be stably maintained at an ideal low level. It prevents material agglomeration due to excessive moisture or denaturation from local overheating, and ensures the purity, whiteness and activity of powder.

Anti-adhesion & Anti-blockage: It solves adhesion and blockage problems of high-moisture materials inside Raymond mills and pipelines. Continuous hot air keeps the inner wall of equipment dry all the time and eases material sticking inside grinding chambers, classifiers and pipelines.

Wide Application Range: It expands the adaptability of Raymond mills to raw material moisture. For materials with different initial moisture content, production requirements can be quickly met by flexibly adjusting hot air parameters.

Working Principle of Hot Air Furnace

Isolated Heat Exchange: High-temperature flue gas generated by fuel combustion is completely physically separated from clean air fed into Raymond mills. Heat is transferred indirectly through high-temperature resistant alloy tube walls to ensure pure hot air without material contamination.

Efficient Heat Recovery: Multi-stage heat exchange loops realize stepwise and sufficient recovery of waste heat from flue gas, greatly improving overall thermal efficiency.

Thermal Conveying: Heated clean hot air is directly delivered to Raymond mills to provide stable heat source for grinding and drying. Low-temperature flue gas after heat exchange is discharged out of the system independently, achieving efficient heat utilization and separation.
