I. Overview of AB Series Airflow Mill Products:
This machine adopts a rotating secondary air elutriation technology, which avoids over-grinding, thereby achieving concentrated particle size, effectively controlling the generation of large particles, and achieving energy-saving effects.
II. Working Principle of the AB Series Jet Mill:
The working principle of a jet mill involves using high-pressure gas to generate supersonic airflow, which drives materials to collide with each other for pulverization. At the same time, the classifier inside the grinding chamber sorts the pulverized materials, thereby obtaining products of the desired particle size. The coarse particles remain in the chamber for further grinding.
III. Features of the AB Series Airflow Mill:
High efficiency: The full utilization of jet energy, along with the optimized design of the impeller structure and classified flow field, significantly improves both crushing and classification efficiency, reduces over-grinding, and thus greatly increases output.
High Classification Precision: A stable and complete classification flow field, along with special sealing measures, reliably prevents the leakage of coarse particles. The product particle size can reach d97 < 5um, with strict control over large particles.
Low Wear: Key components such as the crushing chamber, nozzle, and impeller are designed and installed with wear-resistant structures to ensure the entire machine has no easily worn parts. Combined with an optimized internal cavity design and wear-resistant, non-sensitive materials, the equipment achieves minimal wear and maximum product purity (total impurity content below 4ppm, including impurities introduced by air).
Reasonable structure and multiple functions: This machine can be used as a crusher, a classifier independently, or in a multi-stage classification series, allowing one production run to yield 1 to 6 particle size products. It can also form closed or open circuit operations with other crushing equipment, truly achieving multi-purpose use. Additionally, its compact structure, low height, and easy disassembly and cleaning make operation and maintenance convenient, and product changeovers simple.
The entire process operates under sealed negative pressure, featuring a high degree of automation, an excellent production environment, and stable production processes.
IV. Applicable Scope of the AB Series Jet Mill:
It can be widely used for ultra-fine grinding of chemicals, pharmaceuticals, pesticides, refractory materials, abrasives, additives, flame retardants, electronic materials, AC blowing agents, carbon black, non-metallic minerals, and battery materials. The airflow can utilize compressed air, inert gas, or superheated steam.
This machine can also be used in series with a multi-stage classifier to obtain multi-stage products.
The AB series jet mill is a mill that utilizes opposed jet airflow for crushing and features a classifier at the top, also known as an airflow crushing classifier. The classifier can adopt either a vertical or horizontal structural form, while the nozzle employs a supersonic jet structure, offering the crushing characteristics of ultra-hardness, ultra-fineness, non-wear, and no material contamination. Depending on the product requirements, the jet mill can be used as a standalone unit or in series with a classifier to achieve single-stage or multi-stage products.
