Nitrogen shielded jet mill is based on a fluidized bed jet mill, using nitrogen or carbon dioxide as the grinding working medium, consisting of a nitrogen compression system, a nitrogen filtration system, a crushing system, a classification system, a collection system, a feeding/unloading system, Nitrogen purity test supplement system, nitrogen generation system and electrical control system.

The entire production line of the nitrogen shielded airflow crusher equipment adopts a fully enclosed negative pressure operation, and there will be no dust and dust pollution on the production site. Using PLC programming control, safety measures are multi-pronged and work in parallel, and only one of the measures is effective to prevent potential safety hazards.

The system can process a variety of materials with strong wear resistance and low wear. After the internal protection of the equipment, the product has no iron pollution. The hierarchical flow field technology can obtain the best grinding efficiency and strict particle size distribution, and the grinding particle size can be adjusted arbitrarily between 3-74 microns.

 Features:

  • The scope of application is wide. According to the characteristics of flammable, explosive and oxidizable powder, suitable inert gas can be selected as protective gas.
  • The purity of the inert gas can be controlled according to process requirements and product characteristics.
  • The inert gas is recycled, with low loss and low cost.
  • Reasonable cooling flow field, lower system air temperature, especially suitable for processing heat sensitive low melting point materials.
  • The use of new end face gas sealing technology ensures uniform particle size distribution and improves classification accuracy.
  • Optimize the structure of the equipment and improve the performance of the equipment, which can effectively disperse and separate the agglomerated ultrafine powder and polymer.
  • Optimized grading impeller structure, uniform, stable and complete flow field, low pressure loss of impeller, and accurate classification of materials.
  • Fully sealed operation, pulse automatic dust removal, high-precision filter material filtration, high collection efficiency.
  • The nitrogen shielded jet mill can also be used to disperse metal powder agglomerates, such as iron powder, cobalt powder, titanium powder, alloy powder, etc., to ensure the stability of raw material properties while breaking up.
