Detailed Introduction:
The steam mill utilizes superheated steam that passes through coaxial nozzles to accelerate particles and facilitate collision-based pulverization. The pulverized material is then graded by a classifier, with qualified powder entering the subsequent collection system for gathering, while unqualified material is returned to the mill for further pulverization. Throughout the process, the steam remains in a superheated state, ensuring that production is carried out under completely dry conditions.
2.1 Cost-effectiveness: It effectively utilizes the steam generated from existing waste heat or backpressure steam from low-temperature power generation as a driving force, significantly reducing powder processing costs. If the steam is previously vented without utilization, adopting steam-powered milling can reduce powder processing costs to just 1/5 to 1/8 of those associated with jet milling. This represents a notable energy-saving advantage, especially where low-grade energy sources are available instead of high-grade ones.
2.2 Superior Pulverizing Intensity: Compared to the conventional jet mill's design line speed of 400m/s to 600m/s, the steam mill achieves a pulverizing intensity of up to 1000m/s.
2.3 Compliance with Energy Conservation and Emission Reduction Policies: By fully utilizing waste heat, it aligns with the current national policies that vigorously promote energy conservation and emission reduction, facilitating access to government science and technology funding and national scientific and technological awards.
2.4 Reduced Wear and Maintenance Costs: As the pulverization process relies on material-to-material collisions, the equipment experiences minimal wear. Even if large foreign objects (such as bolts or iron pieces) enter the machine, they will not damage it, resulting in low maintenance requirements, few consumable parts, and low equipment maintenance costs.
2.5 Versatile Particle Size Range: It offers a wide range of particle sizes, capable of processing both ultra-fine powders of 10um and ultra-micro powders of 1-2um as needed.
2.6 Efficient Utilization of Unused Superheated Steam: Again, by effectively harnessing previously unused superheated steam, it aligns with national policies promoting energy conservation and emission reduction, making it eligible for government funding and recognition.
