Air classifiers are mechanical screening devices that separate materials by particle size through vibration. During operation, materials are subjected to forces including gravity, centrifugal force, and inertia as they pass through screening meshes. Larger particles pass through the mesh and fall into the collection bin below, while finer particles exit through the upper discharge port […]

In modern industrial production, precise material classification is a critical process across industries such as chemicals, pharmaceuticals, food, and advanced materials. The performance and quality of final products heavily depend on accurate particle separation. Centrifugal classifiers, as highly efficient and precise particle sorting equipment, have gained widespread adoption due to their unique working principles and

In modern industrial production, precise particle classification is a fundamental step across diverse sectors. Whether it involves raw material processing in pharmaceuticals, refining products in chemicals, or screening materials in food processing, the ability to separate particles accurately by size drives product quality, process efficiency, and overall operational success. The air classifier is a sophisticated

In industrial powder processing and mineral separation applications, selecting the appropriate classification equipment is crucial for achieving optimal product quality and production efficiency.
