Product Description

Operational Principle

Jet Mill used in Lab, whose principle is :  Driven  by  compressed  air through  feeding  injectors,raw  material  is accelerated to ultrasonic speed and  injected  into milling chamber in tangential direction, collided and grinded  into  particle.  The  particle  size  can  be controlled by adjusting longitudinal depth, milling pressure and material feeding speed. Disc type Jet Mill do good performance to gummy materials.


1.Small batch production demand of lab,using the desktop design.

2.The production capacity is 50-300g batch, what's more, it can reach to 300-1000g batch, even 3-5kg batch while changing the design of the collection device. the flexible design completely avoids different machine models usage.

3.Adopt simple bag collecting mode to save cost.

4.Several times grindings to achieve fineness requirement.


It is widely applied to superfine pulverizing for nonmetallic ores, chemical metallurgy, western medicines, traditional Chinese medicine, agricultural chemical and ceramics, fit to be used in Lab.
