Ultrafine pulverized machinery is used in a crushing method, and the ultra-fine pulverized ultrafine pulverizer is developed. With the continuous development of ultrafine pulverization technology, a variety of ultrafine pulverized equipment dry pulverization is system Take the main method of ultrafine powder. Dry ultra-fine pulverization machines are generally divided into two categories: ultra-micro gas flow mill and mechanical ultrafine pulverizer.The airflow classifier has a variety of performance characteristics. Mianyang El Pieces summarize the following kinds of sharing. The airflow classifier is suitable for fine grading of dry microscale products, graded spherical, sheet-like, and irregular shaped particles, can also be graded for particles of different densities. The airflow classifier has a variety of performance characteristics, and Mianyang Erfa powder summarizes the following kinds of sharing.
The grade of grading has a particle size of D97: 3 to 150 microns, and the product particle size is not adjustable, and the variety replacement is extremely convenient.
The grading efficiency (extraction rate) is 60% to 90%, the graded efficiency is related to the material properties and the particle size of the particle size, the material is fluid, and the particle content required to meet the particle size is high, and the efficiency is high. low.
The hierarchical rotation speed is high and the vertex cut is accurate.
Multi-level classifier is used in series, while producing a plurality of particle size sections.
Can be used in series with a ball mill, vibration grind, Raymond mill, constitute a closed circuit loop. The control system uses program control, and the operating state is displayed in real time, and the operation is simple.
System negative pressure operation, dust emissions are 40 mg / m, after silence measures, the equipment operates noise than 75dB (a).
In terms of quality inspection, ALPA powder technology is particularly stricter. It is well known that a manufacturing process of a ultrafine powder is often up to hundreds. As a special equipment, the airflow pulverizer is like a special process, and it is possible to make a big disaster. Therefore, ALPA powder technology has established seven process stop points in the production process, which is strictly controlled by different engineers, and each other is independent and mutual supervision, and it is timely discovery and solve the problem. Any detail is unqualified, it is unable to enter the proceeding process, which is the quality monitoring of AlPa powder technology to the production process.
