In March 2025, Shangli started series production of a high-speed dust ignition-proof motor designed to drive jet mills and other high-speed equipment that operates in combustible dust atmospheres.
Built for jet mills
Jet mills are used in chemicals, pharmaceuticals, food and metal powder processing. They run at high speed for long periods and generate fine combustible dust, so the drive motor needs both high-speed capability and dust ignition protection.
Key features
Dust ignition protection: certified DIP A21 and DIP A22 for use in combustible dust environments.
High-speed design: precision rotor balancing for stable high-speed operation.
Cooling: reinforced cooling fins and air cooling to limit temperature rise at high speed.
Efficiency: meets China energy efficiency grade 2.
Customisation: different ratings and sizes are available to suit the application.
Applications
Besides jet mills, the motor suits pharmaceutical, chemical, food and mining processes with combustible dust. Tell us the mill model, required speed and power through our enquiry form, and see our low-voltage explosion-proof motors for standard dust ignition-proof series.
