QLM fluidized bed pulverizer

Release time: 2018.12.12 | Back

QLM fluidized bed jet mill is an air jet crusher independently developed by our company. It is a new type of ultra-fine crusher which combines the opposed jet technology with the expanding gas jet stream in the fluidized bed. Integrating crushing, classification, mixing and homogenizing mechanisms, this machine is an advanced ultra-fine powder grinding equipment at home and abroad. Realize the unique advantages of on-line operation.
1. The fluidized bed pulverizer has a high impact speed (air flow rate can reach Mach 2 ~ 4), and the particles are impacted by the air jet nozzle, and the impact speed is the superposition of two relative velocities, and the crushing efficiency is high.
2. The fluidized bed pulverizer has low energy consumption. Compared with other types of jet mills, it can save energy by 30-40%.
3. The fluidized bed crusher has minimal wear. Because the main crushing action is the impact and collision of particles in the fluidized bed crusher, high-speed particles rarely collide with the grinding wall and the material does not pass through the nozzle, which can be used for high hardness materials. Crushing (activated carbon, abrasive, tungsten carbide).
4. International new type fluidized bed pulverizer, which integrates air flow pulverization and ultra-fine subdivision into one.
5. Introducing foreign advanced technology, cluster type porous nozzle
6. Optimize the mechanical transmission of the classifier, trouble-free operation, the horizontal classification wheel is used for classification, the cutting accuracy is higher than that of the vertical classification wheel, and the classification efficiency is high. Our company adopts high speed and small classifying wheels to ensure the classification accuracy, which is greatly improved than the domestic use of large wheel low speed airflow grinding.
7. The main components such as nozzles and classification wheels are made of super-hard materials, and are designed and installed with wear-resistant structure to ensure that the whole machine has no wearing parts. Optimized design of the internal cavity structure and wear-resistant and anti-sensitive materials make the equipment less wear and high purity (the total amount of impurities increased is less than 100ppm). More suitable for high and medium hardness powders and materials without pollution
8. The particle shape of the powder material prepared by the fluidized bed pulverizer is good, and the particle size distribution range is narrow. In addition, the air-pulverized products have the advantages of uniform particle size distribution, smooth particle surface, close to spherical shape, high purity, high activity, and good dispersibility.
Output serialization: 35 ~ 3000kg / h; high fineness: d97 = 3 ~ 200μm
9. The grinding chamber is lined with a special wear-resistant material, and other inner surfaces are affixed with wear-resistant materials, which can be used for material hardness Mohs 7 grade.
10. Reasonable design, simple and compact structure, easy to operate.
The company has built a QLM300 production line that can not only allow users to see samples and order, but also undertake ultra-fine processing of mineral incoming materials. It is a "demonstration line" that combines visits, inspections, production demonstrations, experimental research, and in-depth development.
Widely used in chemical, non-metallic ore, abrasives, metallurgy, building materials, light industry, electronics, medicine, food and other industries for various types of ultra-fine powder grinding.
