Technical advantages (superfine grinding)

Ultramicro pulverizer technology is a new technology in the past decade, it on the basis of the traditional crushing technology, the concept of crushing greatly extended forward. Ultrafine powder because of small particles, large specific surface area and therefore have strong activity and show a strange physical and chemical properties, so in magnetic properties, thermal properties, catalytic properties, adsorption properties with the reduction of particles have significant changes, there is a large material does not have the performance effect. Cheap minerals, chemical products by superfine processing, broaden its value with the range of application and produce abnormal increases, its added value increase several times or even more, with the development of new technology products, many industries use a variety of ultra-fine powder material used to improve the quality of our products and make products upgrading to adapt to the demand of the market competition.

With the highly development of modern science and technology, the traditional crushing technology and equipment has been difficult to meet the crushed product size and accuracy is higher and higher demands, in the superfine grinding technology, airflow pulverization is currently recognized can effectively obtain Z small particle crushing method, is an important means of modern powder processing, airflow pulverization can not only preparing superfine powder, And there are narrow product size distribution, good product dispersion, no research body wear and pollution advantages, can be widely used in chemical, metallurgy, mining, energy, electronics, medicine, pesticides, plastics, papermaking, pigments, coatings, dyes, abrasives, food, cosmetics and other industries, as well as some special materials, such as: Ultrafine grinding of polymer materials, advanced electric porcelain materials, magnetic materials, semiconductor materials, fine chemical powder products, catalysts, reagents and chemicals, propellants and other high purity powder products.

Our company's WFQ series fluidized bed airflow grinder is a new generation of ultra-micro airflow grinding equipment, set the international Z advanced multi-nozzle technology, fluidized bed technology and turbine classification technology in one, to achieve the flow field diversification, material layer flow state, horizontal classification of the combined technology system, is the direction of airflow grinding development.

First, crushing introduction

1. The crushing chamber uses mechanical force to overcome the internal cohesion of solid materials to achieve the unit operation of crushing. It is customary sometimes to split large pieces of material into small pieces of material operation called crushing; The operation of splitting small pieces of material into fine powder is called grinding or grinding, both of which are collectively called grinding. The size of the material particle is called the particle size, which is the representative size of the degree of crushing.

According to the size of the crushed material and finished product particle size, crushing can be divided into coarse crushing, medium crushing, micro grinding and ultra-micro grinding four kinds: (1) coarse crushing: the original particle size in the range of 40~1500mm, finished particle size is 5~50mm; ② Medium crushing:

2. The particle size of raw material is 10~100mm, and the particle size of finished product is 5~10mm; ③ Micro grinding (fine grinding): raw material particle size 5~10mm, finished product particle size less than 100μm; ④ Ultrafine grinding (ultrafine grinding): raw material particle size of 5~10mm, the finished product particle size of 10μm or less.

Two, technical characteristics

1. Ultrafine grinding technology of WFQ series fluidized bed airflow crusher is using supersonic airflow grinding, low temperature freezing grinding and other methods, completely different from the previous pure mechanical grinding method. Local overheating will not occur in the process of crushing, and even can be crushed at low temperature, fast speed, instant completion, so Z maximum retention of the biological active ingredients of the powder, in order to facilitate the production of high quality products required.

2. Uniform particle size distribution: due to the use of supersonic air pulverization, the force distribution on the raw material is quite uniform. The setting of the classification system not only strictly limited the large particles, but also avoided the occurrence of crushing, so as to obtain the ultrafine powder with uniform particle size distribution, but also increased the specific surface area of the powder to a large extent, so that the adsorption and solubility of the powder also increased accordingly.

3. Improve the utilization rate: after the object is ultrafine grinding, the ultrafine powder with nearly nanometer fine particle size can be directly used in preparation production, while the conventional grinding products still need some intermediate links to meet the requirements of direct production, which is likely to cause raw material waste. Therefore, this technology is especially suitable for crushing precious and rare raw materials.

4. Reduce pollution: ultrafine grinding is carried out in a closed system, which not only avoids the pollution of the surrounding environment by micro powder, but also prevents the dust in the air from polluting products. Therefore, using this technology in food and medical care products, microbial content and dust can be controlled.
