China Drying Network News With the rapid development of modern high-tech and strategic new materials industries in China, “ultra-fine powder materials”, which are known as new materials in the 21st century, are applied to almost all industries of the national economy.

One of the most important and important quality indicators for powder materials is their particle size. However, in the current stage, the domestic sorter sorting granularity is relatively coarse, and the product granularity is uneven. Generally, it can only reach about 10 microns (1200 meshes), and there are low output, high energy consumption, poor use reliability, and low sorting efficiency. Disadvantages.

In order to solve this problem, the national high-tech enterprise Zhejiang Fengli Crushing Equipment Co., Ltd., based on the introduction and absorption of international advanced powder equipment technology, adopts the advanced principle of turbine grading, and is innovatively developed to have a high performance and wide applicability. A new generation of ultrafine powder material classifier - high-efficiency turbo super classifier, its core technology has recently obtained a national utility model patent (Patent No. 6; authorization announcement number: CN202290575U). This is another honor after the product has obtained the appraisal of Zhejiang science and technology achievements. The machine can freely adjust the product particle size, ideal grading effect, uniform particle size distribution, convenient maintenance, wide range of grading, high classification accuracy, and provides a fine to low-to-medium-hardness ultrafine powder material for powder production enterprises. Grading equipment.

Superfine classifier is the key equipment in powder production process. It not only can precisely control the particle size distribution of powder products, but also can greatly reduce the energy consumption of the entire grinding system. The high-efficiency turbo super classifier introduced by Zhejiang Fengli is a dry material air classifier, which has a number of advanced process technologies: (1) The graded turbines and their associated components are both domestically adopted and internationally leading dynamic airflow seals. The device has the characteristics of reasonable structure, accurate classification, narrow range of product particle size distribution, high efficiency, and low energy consumption. (2) The blades of the staged impeller adopt special high-strength and wear-resistant materials, which improves the stability of high-speed operation, makes the grading finer, and has a longer service life. When the viscous and cohesive materials are processed, the fine powder is greatly reduced. Deposition in the feed tube. (3) High degree of automation and easy operation. (4) High classification accuracy, wide range of classification, can adjust product granularity between 3 and 150 microns. With secondary air intake and high-precision turbine, fine material up to 3 microns can be obtained. Rotor gradeable high hardness material using special materials. (5) Small footprint, low wear parts, and low cost. (6) The advanced turbine scroll design makes the noise very small, the operation is very stable, and the vibration is small.
