Working principle of Pharmaceutical spiral jet mill
The spiral jet mill utilizes a high-speed jet of compressed air or gas to grind particles into a fine powder. The particles are fed into the mill through a hopper and are accelerated by the jet stream. The particles collide with each other and with the walls of the mill, resulting in the micronization of the particles.
The pharmaceutical spiral jet mill is used in a variety of applications, including the micronization of active pharmaceutical ingredients (APIs), excipients, and other materials. It is also used in the production of inhalation powders, where a narrow particle size distribution is required for optimal drug delivery.
Technical Advantages of Spiral Jet Mill
- Without any rotating parts, CNC precision machining, no welding seam, easy to clean.
- No medium grinding, the grinding chamber can be protected by stainless steel and wear-resistant ceramics to ensure product purity.
- Low temperature grinding, especially suitable for grinding heat-sensitive, low-melting, sugar-containing and volatile materials.
- The grinding process is extremely short, the crushing efficiency is high, and the over-grinding is less.
- Suitable for grinding, dispersing and depolymerizing, and particle shaping of materials with various hardness.
- The whole system is closed, without dust, low noise and easy to operate.
