Gas-solid ratio and feed particle size can affect gas flow pulverizer processing effects

  The pesticide raw material is subjected to a gas flow, and the powder particles can be subtracted to 5 to 10 μm or less, which significantly improve its uniformity, dispersibility, and the contact area of ​​the dosing. Strife, insecticidal and weeding effect are significantly enhanced, which greatly reduces the use of pesticides. Moreover, the ultrafine powder has a large surface area, strong adsorption capacity, and rain-resistant to the rain, thereby maintaining long-term pesticides. Accordingly, the ultrafine powder is accelerated due to surface activity in agricultural and sideline products and environments, so the amount of pesticide residues decreased, and pollution is reduced.

  Shandong Erpai online customer service introduces the partial and characteristics of the airflow pulverizer: the airflow pulverizer is composed of several parts of the feed, smash, slag, support, and transmission, next we will Let's take a look at its characteristics.

  ● The inner settlement device, the vertex cut is accurate, the product particle size D97: 2-45 microns can be adjusted, the granular shape is good, the particle size distribution is narrow.● Low temperature without medium, especially suitable for thermal sensitivity, low melting point, chitosan and volatile materials [2].

  ● Equipment disassembly and packing is convenient, and the inner wall is smooth without dead angles.

  ● The complete system is closed, the dust is small, low noise, and the production process is clean and environmentally friendly.

  ● The control system uses program control and easy to operate.

  The main factors affecting the pulverization effect of the airflow pulverizer are: the temperature and pressure of the gas ratio, the feed particle size, and the temperature, and the pulverization aid.

  1 Gas-solid ratio

  When the gas ratio is not only an important technical parameter, it is also an important economic indicator. The gas is too small, because the kinetic energy of the airflow will affect the fineness of the product; too high gas ratio, not only wasting energy, but even won the dispersion performance of certain pigments. When the superheated steam is a working article, the hard material after the calcination is generally controlled at 2 to 4: 1; the material after the pulverization surface is generally controlled from 1 to 2: 1.

  2 Feed particle size

  Although the feed particle size is not that the gas is more important, but when the hard material has a strict requirement, it is controlled when the calcined calcination of titanium Bi powder is controlled at 100. ~ 200 is well; the materials after the treatment of the surface treatment are generally 40 ~ 70 mesh, Zuida does not exceed 2 to 5 mesh.

  Airflow pulverization machine is widely used in chemical, mining, abrasive, refractory, battery materials, metallurgy, building materials, pharmaceutical, Ceramics, feed, new materials, environmental protection and other industries and various dry powder materials are very good, and they can fully meet the superfine crushing of various materials, The fineness is adjustable, and the yield is adjustable.

  Shandong ALPA Powder Technology has always firmly convinced that the basis of the global brand is the improvement of product and service quality, and behind the quality of the quality is a fear of market.
