Medical jet grinder working temperature is too high, the flow rate will become faster

The medicine jet grinder is a kind of mechanical equipment used in the field of medical production as its name implies. The medicine jet grinder is mostly used for crushing Chinese and western medicine particles. How it works!

The price of pharmaceutical jet mill is also relatively reasonable in the market. The jet mill produced by Kunshan Qianwei Powder Equipment Co., Ltd. has been recognized by many customers in the market. In addition to the fine particle size, jet mill products have the characteristics of narrow particle size distribution, smooth particle surface, regular particle shape, high purity, large activity, and good dispersibility. Due to the adiabatic expansion effect of Joule Thomson due to the adiabatic expansion of compressed gas during the pulverization process of the jet mill, it is also suitable for ultrafine pulverization of low melting point and heat sensitive materials. The air-solid ratio in the pulverization process of medical jet mill is an important technical parameter and an important index. If the air-solid ratio is too small, the kinetic energy of the air flow will be insufficient, which will affect the fineness of the product. However, if the gas-solid ratio is too high, not only energy will be wasted, but even the dispersibility of some pellets will be poor. Feed size, when crushing hard materials, there are more stringent requirements for feed size. In the case of titanium powder, when crushing the calcined material, it is necessary to control 100-200 mesh; the material after crushing the surface treatment is generally 40-70 mesh, and cannot exceed 2-5 mesh.

The working temperature of the medicine jet mill is also a factor that affects the working efficiency. When the temperature of the working fluid is too high, the gas flow rate will increase. Taking air as an example, the critical speed at room temperature is 320 m / s. When the temperature rises to 480 ° C, the critical speed can be increased to 500 m / s, that is, the kinetic energy increases by 150%. Therefore, increasing the temperature of the working fluid is conducive to improving pulverization. The pressure of the working fluid is the main parameter that produces the jet velocity, and it is also the main parameter that affects the crushing fineness. Generally, the higher the pressure of the working fluid, the faster the speed and the greater the kinetic energy. When the titanium powder is pulverized by superheated steam, the vapor pressure is usually 0.8 to 1.7 MPa, and the pulverized calcined material is generally higher, and the pulverized surface-treated material may be lower.

The above are the possible factors introduced by the pharmaceutical air grinder manufacturers that affect the working efficiency of the pharmaceutical air grinder. You can simply understand it. Users who need to buy eddy current grinder, disc air grinder, ultrafine grinder products, please call 138-0626-1685.
