The grading system of the airflow pulverizer is the key to control particle size

  The problem of ordinary ultra-micro gas flow is: high manufacturing cost, large investment, high energy consumption, too much powder processing, so that it is also subject to certain fields; difficult to make submicron Level products, product particle size is best in 10 um, and the output is sharply decreased at 10 um, and the cost is rapidly rising; the single-machine handling capacity of gas flow is smaller (both less than 1 ton hour, can not adapt to large-scale production needs; The wear problem of equipment processing accuracy and material is still plaguing equipment manufacturers and factory users.For more than 30 years, the airflow pulverizer has gradually penetrated into various fields in industrial processing, such as ore, chemical, ceramics, The metal, battery, rare earth and other fields have the figure of the airflow mill. As the ultrafine pulverized equipment, Zui advantageous airflow pulverin is used to high precision, high efficiency, can be said to be the dry physical pulverizer to achieve the most Exquisite granular equipment, but how does it reach the fine particle size of ZUI? What is it to control the particle size? The following is introduced by Erp.

  The airflow pulverizer is composed of a feeder, a crushing host, a grading system, a cyclone separator, a dust collector, a guide fan. The grading system is a key portion of the control granularity. After the gas stream is highly impact, it is required to meet the requirements. The fine particles pass through the hindle collector, and the crude particles cannot be returned to the pulverizing chamber through the impeller gap. The grading impeller can control its speed to adjust the range of granular particles. This The method of controlling the particle size is more efficient, dust pollution, anti-blocking, and other advantages in the traditional screen grading method, and in terms of the narrow range of gradular particle size ranges from the screen grade. Airflow pulverization The machine is the most advanced ultrafine pulverized model in the ultrafine pulverizer, which can meet the hardness from 1 to 10, the finished particles from 2 μm to 45 μm no extremely adjustable, particle size distribution stenosis. Airflow pulverizer is relatively The advantage of the pulverized equipment is that the amount of impurities in the finished product is small, the particle size distribution is easy to control, and the distribution is concentrated. In the dry pulverization, the airflow pulverizer is suitable for a powder, which is relatively high. Currently. Each industry generally selects the air current pulverizer, mainly looks at the superfine pulverization capabilities, automation control reduces human control, the later maintenance is convenient, the lifetime is less, the product quality is goodFeatures of granularity controllable, distribution concentration, very difference.
