Inert Gas Spiral Jet Mill

Inert Gas Spiral Jet Mill is a type of milling equipment that is commonly used in the pharmaceutical, food, and chemical industries. It is known for its ability to produce fine particles with a narrow particle size distribution. This is achieved by using high-speed jets of inert gas to grind and mill the material.

Another advantage of using an Inert Gas Spiral Jet Mill is its ability to process heat-sensitive materials. The use of inert gas as a cooling agent allows the material to be processed without the risk of degradation or damage due to heat. This makes it an ideal choice for processing materials such as pharmaceuticals, food ingredients, and chemicals.

Working principle of Inert Gas Spiral Jet Mill

The process of milling with an Inert Gas Spiral Jet Mill involves the material being fed into the mill where it is accelerated by the high-speed jets of inert gas. The material is then forced through a spiral path in the milling chamber which further reduces the particle size. The inert gas used in the process acts as a cooling agent, preventing the material from overheating and ensuring a consistent particle size.

One of the key benefits of using an Inert Gas Spiral Jet Mill is its ability to produce particles with a very narrow size distribution. This is particularly important in industries such as pharmaceuticals, where the size and shape of particles can have a significant impact on the effectiveness of the drug. The narrow particle size distribution also ensures that the material is more easily and efficiently processed downstream.

Technical Advantages of Inert Gas 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.
