Steam Jet Mill

Steam Kinetic Mill Principle and Advantages

System Principle and Composition

The steam kinetic mill is designed specifically for the operational characteristics of thermal power plants, utilizing low-to-medium-grade steam as the power source. Through a unique supersonic airflow collision technology, it accelerates, mutually collides, and shears fly ash waste residue, achieving ultrafine pulverization. After pulverization, the materials are subjected to turbine airflow classification. Qualified fine powders enter the dust collection system for collection, while coarse powders are returned to the pulverizing chamber for further pulverization. The entire ultrafine pulverization process is carried out in a fully dry environment, and the purified air is discharged through the induced fan.

The steam kinetic mill system typically consists of four main parts:

1. Feeding System - Responsible for supplying the system with the fly ash waste residue to be processed.
2. Main System - Includes the steam unit and mill bed, utilizing steam as the power source to pulverize the materials.
3. Classification System - Uses a turbine airflow classifier to sort the pulverized materials, ensuring powder quality.
4. Collection System - Collects qualified fine powders and redirects unqualified materials for further processing.

Advantages

1. Low Cost and Energy Consumption - Compared to traditional mechanical pulverization and airflow pulverization, the steam kinetic mill has lower costs and energy consumption, with production costs only 1/5 to 1/8 of those of airflow mills.
2. Efficient Pulverization - The steam kinetic mill achieves nanometer-level classification, with better particle sphericity and particle size distribution uniformity. Its pulverization intensity is more than twice that of traditional airflow mills, and its impact force is more than four times that of conventional airflow mills, resulting in significant energy savings.
3. Efficient Utilization of Waste Heat - The steam kinetic mill efficiently utilizes the superheated steam from power plants as its power source, aligning with national policies on energy conservation and emission reduction and enhancing the utilization of waste heat in power plants.
4. Easy Maintenance - The pulverization process of the steam kinetic mill relies mainly on the mutual collision of materials, resulting in minimal equipment wear and low maintenance costs.
5. Wide Range of Applications - The steam kinetic mill is suitable for the ultrafine pulverization of various temperature-resistant materials, such as fly ash, desulfurization waste residue, titanium dioxide, coal powder, petroleum coke, carbon black, carbon, blast furnace slag, steel slag, graphite, mica, talc, quartz, calcite, barite, diatomite, aluminum/magnesium hydroxide, metal oxides, and more.
