There are shortcomings in the speed and noise of air flow ultrafine pulverizer

Airflow crusher is under the action of high-speed airflow, the material through the impact between its particles, airflow impact shear action on the material and the impact of other parts of the material, friction, shear and material crushing equipment. It is reported that since 1882, Gosselin proposed the use of airflow kinetic energy powder, the market appeared a variety of types of airflow crusher. At present, the industrial application of more airflow crusher mainly spray, circulating, flat and fluidized bed airflow crusher. Among them, flat, fluidized bed jet mill in pharmaceutical, pesticide, and other fields are widely used.

Industry is introduced, compared with mechanical mill, jet mill, crushing strength, high energy utilization, jet mill can reach 2% to 10%, while the common crusher is only 0.6%, the equipment has simple structure, can be sterile, clean convenient, also of LiaoDu product and fine, up to several microns submicron even, and keep neat and smooth surface. In addition, the airflow crusher can realize crushing and drying, crushing and mixing, crushing and chemical reaction and other joint operations in the machine.

Although the advantages of the airflow crusher is obvious, but there are also shortcomings, for example, auxiliary equipment, high cost, crushing system blockage will occur when the phenomenon of feeding, ejected a large amount of dust, deteriorating the operating environment; Crushing material has limitations, such as oil, water, fiber more material is not easy to crush.

Many users also reflect that the domestic airflow grinder is also common at present there is a slow grinding speed, noise and other defects.

It is understood that China's airflow crusher machinery industry after twenty years of development, the market size has been very large, in the pharmaceutical, chemical and other fields have been involved. But from the overall level of the industry, China's jet mill technology is relatively backward compared with foreign countries, the development of certain constraints.

Experts said that at present, the domestic airflow mill r & D enterprises are facing more than 90% overcapacity. Therefore, the sustainable development of the airflow crusher industry needs to take into account many factors, get rid of the problems of loud noise, limited materials, slow grinding speed and low efficiency, and develop a crusher in line with the needs of the pharmaceutical industry, with high technical content of products to conquer the market.

With the improvement of equipment structure and the improvement of crushing technology, in the process of large-scale and automatic exploration of the device, the defects of domestic airflow crusher are gradually being overcome.

Is understood to have developed a new type of combination crusher enterprise airflow crushing equipment, its performance is superior to the traditional jet mill and mechanical crushing, with low energy consumption, short technological process cover an area of an area small, no dust pollution, small heat, finished product fine granularity, crushing range, any material moisture, feed particle size no wait for a characteristic, can replace imported equipment.

In general, China's airflow crusher industry is breaking through the development bottleneck, with the arrival of the era of intelligent automation, intelligent, automation has become the inevitable trend of the development of the future machinery industry, in this context, the airflow crusher industry should also cater to the needs of the market, constantly moving toward intelligent automation.

In addition, with the continuous development of the pharmaceutical industry and the intensification of enterprise competition, pharmaceutical companies pay more attention to cost control. High performance, high reliability, high mobility, good maintainability and economy are becoming the products that users are pursuing. Industry said, modular design principles, methods and technology or will become an effective way to explore air mill manufacturers.
