In recent years, China\u2019s rapid industrial development has created more opportunities for the mechanical equipment industry in deep processing. Particle size plays a crucial role in the bioavailability of certain medical products, making pulverization vital. The air pulverizer has become essential in pharmaceutical pulverization due to its low temperature, short production cycle, and high powder collection rate. It provides uniform, fine particle size distribution. The air pulverizer, also known as the air jet mill, jet mill, or energy flow mill, uses high-speed airflow (300-500 m\/s) or superheated steam (300-400\u00b0C) to ultra-finely pulverize solid materials. As a widely used ultra-fine pulverization device, the air pulverizer is applied to superhard materials. The materials include chemicals, pharmaceuticals, foods, and metal powders. Some customers have mentioned that while the air pulverizer has a wide range of pulverization particle sizes, the pulverization effect varies. Why is this?<\/p>\n\n\n\n
