High Pressure Steam Jet Mill QAB Series - Leading China Suppliers & Factory for Advanced Powder Processing Solutions
Working Principle
QAB series high pressure steam jet mill uses high temperature and high pressure superheated steam to accelerate particles through the coaxial nozzle and collide and crush them. The crushed materials are classified by the classifier, and qualified powders are collected by the collection system at the back, and unqualified materials are returned to the pulverizer for further crushing. The steam of the entire system is kept in an overheated state, and the production is carried out under the full dry method.
Equipment Characteristics
- It can make full use of the steam generated by the existing waste heat or the back-pressure steam after low-temperature power generation as power, which can effectively reduce the cost of powder processing.
- If the existing steam is evacuated before it is actually used, after using steam power mill, the cost of powder processing will be only 1/5-1/8 of the cost of air flow mill processing.
- Energy-saving advantages. Where conditions permit, using low-grade energy is far more energy-saving than using high-grade energy.
- Comparison of crushing intensity: The design linear speed of conventional airflow mill is 400m/s~600m/s, while the crushing intensity of steam mill can reach 1000m/s.
- Make full use of waste heat, comply with the current requirements of the country's vigorously promoting energy conservation and emission reduction policies, and easily obtain the support of government science and technology funds and national science and technology awards.

Frequently Asked Questions
Q: How does the QAB series steam jet mill achieve particle crushing?
It utilizes high-temperature and high-pressure superheated steam to accelerate particles through a coaxial nozzle, causing them to collide and crush each other in a completely dry process.
Q: How cost-effective is the steam jet mill compared to traditional airflow mills?
By utilizing existing waste heat or back-pressure steam, the processing cost can be significantly reduced to only 1/5 to 1/8 of the cost of conventional air flow mill processing.
Q: What is the crushing intensity of the QAB steam mill?
While conventional airflow mills have a design linear speed of 400m/s to 600m/s, the crushing intensity of the QAB steam mill can reach up to 1000m/s.
Q: What materials can be processed by this equipment?
It is highly suitable for processing materials like aluminum hydroxide, silicon dioxide, fly ash, silicon carbide, and titanium dioxide, achieving particle sizes down to the nanometer level.
Q: What are the capacity options for different QAB models?
The capacity ranges from 20-50 kg/h for the QAB300 model, 50-80 kg/h for the QAB600 model, up to 100-200 kg/h for the QAB1000 model, depending on steam consumption.
Q: Does the steam jet mill support energy conservation initiatives?
