Factors affecting proper coolant application when grinding ...

Bernoulli's energy equation can be used to predict the pressure that creates the desired jet velocity. For example, a grinding wheel moving at 12,000 sfm (3,657 m/min.) requires a nozzle pressure close to 270 psi (18.6 bar) for the coolant jet to match the wheel speed. Lower wheel speeds require lower pressures.

In Grinding, Coolant Application Matters

The jet coming from the end of these nozzles can be very dispersed, leading to air entrainment. Other disadvantages include: Lack of stiffness when subjected to the reaction force of the jet. The nozzle must be placed very close to the grinding zone to offset the dispersed jet, risking damage by the wheel and the fixture.

Jet mill working principle - Jet mill

Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

If the ambient temperature is 35 C (95 F), the winding total temperature would be: 65 + 35 = 100 C. If motor is so constructed that its surface is about 20 C cooler than the winding, the surface temperature would be: 100 – 20 = 80 C (176 F)—i.e., much too hot to touch safely!
