Ultrafine pulverized machinery is used in a crushing method, and the ultra-fine pulverized ultrafine pulverizer is developed. With the continuous development of ultrafine pulverization technology, a variety of ultrafine pulverized equipment dry pulverization is system Take the main method of ultrafine powder. Dry ultra-fine pulverization machines are generally divided into two categories: ultra-micro gas flow mill and mechanical ultrafine pulverizer.

The airflow pulverizer is a very practical and convenient industrial crushing equipment. Most chemicals, polymer materials need to be used in Shandong El Pie Powder Technology Co., Ltd., airflow pulverizer, gas crushing effect, fine particle, affordable.

The pulverization particle size of the airflow pulverizer is wider, the operation is simple, but during the pulverization process, the crushing effect is often different. The pulverization effect of the airflow crusher is mainly affected by the following factors: gas-solid ratio, feed particle size, working fluid temperature and pressure, and pulverization aid. The gas-resistant ratio of the airflow crusher is both an important technical parameter and an important indicator. The gas is too small, and the air flow can be insufficient, which will affect the fineness of the product. However, the gas is too high, not only wasting energy, but also deteriorates the dispersion performance of certain pigments. When pulverizing hard materials, there is also strict requirements for the particle size. In terms of titanium powder, it is generally controlled at 100/200 mesh when pulverizing calcination, and the material after pulverizing surface is generally 40/70, and it is not suitable for more than 2/5 mesh.

When the temperature of the gas flow pulverizer is too high, the flow rate of the gas will accelerate. 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, which means that the kinetic energy has increased by 150%. Therefore, increasing the temperature of the working fluid is conducive to improving the crushing effect. The pressure of the working fluid is both the main parameters of generating jet velocity, but also the main parameters affecting the fineness of the grinding. In general, the higher the pressure of the working fluid, the faster the speed, the greater the kinetic energy. So what kind of pressure should I choose? Those skilled in the art depends mainly on the crushing and fineness requirements of the material. When the titanium powder is pulverized with superheated steam, the vapor pressure is generally 0.8 ≤ 1.7 MPa, and the calcined material after pulverization is generally low, and the material after surface treatment is low.

The above is the working principle analysis of the Manufacturer of Shandong El Passenger Ragemaker, which needs to purchase airflow pulverizer, ultrafine crusher, swirl crusher, discDifferent crusher, medical airflow crusher, ultrafine crusher, cone mixer, herbal crusher, traditional Chinese medicine crusher users welcome phone consultation.

ALPA adheres to the concept of "fulfilling social responsibility, excellent corporate citizen", and a 1,000 yuan public welfare fund will be donated for each sale of a special person to rescue children and difficult workers in the mountainous poverty. Alpa adheres to this commitment from beginning to end to actually act. The development of the company is inseparable from the support of the government and the people, and actively undertakes social welfare responsibility is an important responsibility of enterprises. It is an important manifestation of enterprises to return to society and reward customers for a long time.
