Japan's Kakouki ST-type air jet mill for food and cosmetic applications is a pneumatic fine grinding machine. Its features include the use of high-speed rotation of blades installed in the crushing chamber to generate a powerful vortex, causing raw materials to collide with each other (natural crushing) for grinding. This crushing method achieves a self-grinding effect on the raw materials and is suitable for a variety of materials, such as rice, tea leaves, soybeans, wheat, barley, coffee beans, food, pharmaceuticals, vitamins, traditional Chinese medicine, glass, polyethylene, talc powder, wood chips, carbon powder, and more.。
