Desktop micro airflow crusher

The development purpose of the NAO series airflow mill is to achieve ultrafine crushing experiments on a small number of samples and achieve a certain recovery rate. This series is particularly suitable for ultrafine grinding of high-value samples such as pharmaceuticals.
The equipment itself is very compact, making it easy to conduct experimental operations on a flat surface, and later disassembly, cleaning, and assembly are also easy to operate.

Basic Principles

The powder is fed into the feeding nozzle by an electromagnetic vibration feeder, and is sprayed into the crushing chamber by the action of compressed air for feeding. The high-speed airflow sprayed from the feeding nozzle forms a supersonic logistics, causing mutual interaction within the logistics

Collisions, shearing, and friction with the walls of the crushing chamber are used to achieve the goal of crushing into fine powder. During high-speed logistics and crushing processes, particles of different fineness will produce different levels of separation in the rotating airflow

The qualified fineness powder is carried to the discharge pipe by the exhaust airflow due to the centripetal airflow force being greater than its centrifugal force, and the finished product is collected through a cloth bag. The larger particles will move along with the flow

Continued crushing process.
