An apparatus of the annular supersonic target jet mill was created to validate the theoretical design. Two types of experiments were implemented to estimate its performance. The validation experiments confirmed that the gas speed in the collision chamber was approximately 600 m/s and the supersonic flow could deliver a kinetic …
In this work, a new supersonic target jet mill based on aerodynamic theory is presented according to the flow field of a traditional jet mill, and the particle size reduction of boroncarbide and silica in the collision tests showed that the accelerated particles concentrated in the su personic flow center collided on the targets precisely with high …

A supersonic jet mill is a machine that grinds large-sized solid materials to the required size. According to the size of the ground material or crushed material, the mill can be divided into a coarse crusher, a medium crusher, a fine mill, and an ultra-fine mill. There are four kinds of external forces applied to the solid during the grinding ...
jet), and Lis the dimension in a gas jet where the probe beam passed through. Since the supersonic slit nozzle has an opening angle along the x-axis, the jet dimension will gradually become wider. Accord-ing to the geometric shape of the supersonic slit nozzle, L can be approximately expressed as 0.5 + 0.9(5 + x) (mm), where x is the
The crushing chamber of the flat jet mill is in the shape of a horizontal disc, and it is also called a horizontal disc jet mill. It is composed of grinding chamber, separation device, feeding device, air duct, etc. (Fig. 1).The working principle is like this: the compressed gas (air, superheated steam, or inert gas) generates a high-speed jet …
Chemical Engineering : Supersonic Jet Mill PJM : Principle | NPK : Nippon Pneumatic Mfg. Co., Ltd. Collision plate type supersonic Jet Mill SPK TOP. Supersonic vortex airflow pulverize particles to collide with the center of the collision plate for pulverization. Coarse powder is circulated back to the grinding section.
