Qu’est-ce que le coke d’aiguille et pourquoi est-il important ?
Needle coke is a high-performance carbon material with a metallic luster and silver-gray color. Its surface texture is fibrous or needle-like, with a slippery feel. It contains small, oval-shaped pores inside. Needle coke consists of large molecular polycyclic aromatic hydrocarbons with flat aromatic layers. It has a graphite-like microcrystalline structure with high unit orientation. The […]
Optimisation du traitement de la poudre de NdFeB : le rôle crucial des broyeurs à jet protégés par azote/argon dans la prévention de l’oxydation et l’amélioration de l’efficacité
The application of nitrogen/argon-protected jet mills in the ultrafine grinding of neodymium iron boron (NdFeB) materials. NdFeB magnets are known for their high magnetic energy and strength. They are crucial in many industries, including electronics and renewable energy. Processing them into ultrafine powders is tough. This is because they are highly reactive, pyrophoric, and prone […]
Broyeur à jet ou broyeur à classification pneumatique : faire le meilleur choix
Choosing between a jet mill and an air classifier mill depends on your needs. Jet mills excel at making ultra-fine powders with precise particle size control. They are ideal for low-contamination industries. They use high-speed gas jets to grind particles. They are suitable for dry, hard materials. In contrast, air classifier mills are versatile. They […]
Comment fonctionne le processus de classification dans un broyeur à jet d'air ?
A jet milling’s classification process is vital for reducing and separating particle sizes. This is crucial in industries like pharmaceuticals, food processing, and materials science. This process uses high-velocity air jets for fine grinding. It also classifies particles by size and density. Knowing how this process works can improve efficiency, product quality, and energy use. […]
Taille des particules ? Taille des mailles ? Comment convertir les mailles et les microns ?
In general, mesh number × aperture (micrometers) ≈ 15000. For example, a 100-mesh screen has a 150-micron aperture. A 200-mesh screen has a 75-micron aperture. A 300-mesh screen has a 48-micron aperture. A 500-mesh screen has a 30-micron aperture. Below is a conversion between common mesh numbers and particle sizes. Mesh Micron (μm) Mesh Micron […]
Comment le pulvérisateur à jet assure-t-il une pureté élevée lors du broyage ?
In the world of particle size reduction, keeping the product pure is key. This is especially true in industries where the final product’s quality matters a lot. The jet pulverizer, a cutting-edge air-based grinding tech, is crucial for keeping the grinding process pure. It uses compressed air to efficiently cut down particle sizes while keeping […]
