Investigation report on various factors of development of small airflow ultra-fine pulverizer

Nowadays, there are many difficulties in the development of small airflow grinder in Our country. The reason is that after more than ten years of development, all aspects of technology can be improved have been improved. It is very difficult to have new progress. Small mill enterprises are also more and more, which also increases the competition between manufacturers, domestic and foreign mill compared, China's technology is relatively backward, this is also a small mill enterprise development constraints.

The price of iron and steel raw materials rose rapidly in the past few years, but the difference is that the cost pressure of the equipment manufacturing industry was mainly reflected in the labor cost from last year, and the demand of the international market kept shrinking. Although in recent years the market of small and medium-sized crusher industry in the trend of warming, but the cost is always hanging in the head of equipment manufacturing enterprises a knife. Due to the low threshold of small mill industry, competition has been very fierce. If the cost is not well controlled, the profitability of small and medium-sized equipment manufacturing enterprises are a problem. But to the long-term survival of an enterprise, the upgrading of small crusher is very important, The Times are changing, if the enterprise is unchanged will only go to extinction. Small airflow crusher industry still need to seek a breakthrough, from the start of technological innovation. Although the national implementation of high-grade CNC machine tools and basic manufacturing equipment of science and technology major special projects, and plans to 2020 four fields of high-grade CNC machine and basic manufacturing equipment 85% based on domestic, only two large efficient CNC automatic stamping production line project successfully commercialized, Further work is needed on key components and high-end CNC systems.

The application of grinder is very extensive, in the product processing, drug grinding and other fields have made outstanding contributions. Its classification also has mechanical crusher, airflow crusher, supersonic small airflow crusher and other categories, they are each playing their unique role in all walks of life. Supersonic small airflow crusher is mainly used in some laboratories. Because it is small, they have all kinds of advantages. Let's take a look at what the advantages are.

(1) High efficiency, jet flow to make full use of, greatly improve the grinding efficiency.

(2) small wear "fluidized bed + vertical turbine classifier" can process ultrafine powder in high purity and narrow band, avoiding the wear of the grinding part of "spray type + vertical classifier" and the wear of the classification part of "fluidized bed + horizontal classifier". Under the same material, the service life of equipment wearing parts is equivalent to 20 times of similar international products.

(3) The classification accuracy of the supersonic small airflow grinder is high, stable, complete classification flow field and special sealing measures, reliably prevent the leakage of coarse particles. Vertical turbine classifier and fluidized bed combined to form internal circulation, to ensure qualified product particle size D97=2 ~ 74μm.

(4) Less over-comminution. The unique grading flow field reduces the gas-solid concentration in the grading area and avoids over-comminution.

(5) variable combination structure can be used as a machine, both can be used as a crushing classifier, and can be used as a separate classifier.

(6) Fully enclosed negative pressure operation, no dust pollution.

(7) Supersonic small airflow crusher is easy to operate and maintain, quick disassembly and washing, and low noise.

(8) The equipment is easy to disassemble and clean, and the inner wall is smooth without dead Angle.

(9) In line with GMP: the contact part with the material is made of high quality austenitic stainless steel, the equipment is round, no dead Angle, using no bolt and joint design, all using clamp connection, easy to disassemble and install, easy to clean.

The above is the advantages of supersonic small airflow crusher, we all want to understand their needs, choose a reliable quality, excellent performance of the crusher.
