Most of the mixer grinders come with a motor speed ranging from 10,000 to 23,000RPM. While operating the appliance, do not run it on high speed for a long time. For most of the tasks, medium speed or speed up to 15,000 RPM is sufficient enough. Finally, a powerful motor lets the blades operate at more rotations per minute which enables to grind the ingredients within a less period of time. 5 ...

Reducing wheel size to slow down grinder speed Generally speaking, the smaller the wheel size, the slower the grinder speed. So as your grinding wheel wears down, it will also slow down. The thickness of the wheels is also significant.

If the motor speed rises above that set by the lever, the centrifugal device or switch opens two contacts and inserts a resistance R in the power circuit to the motor, which causes the motor speed to decrease. If the motor runs too slowly, the centrifugal device will close the two contacts and short circuit the resistance so that the motor speed .

Basically the speed of the output pulley becomes the input speed for the next stage, and you can find the -pulley drive. If the input speed is 75 rpm, the output speed equals 75 rpm divided by 3 or 25 rpm. In turn, one can find the output torque from the driver pulley to the driven pulley by plying the input torque by the velocity ratio. Pulleys and Speed.

Cut a groove in the outside of your drum, stick an o-ring in it, and run the bare motor shaft directly against this. You can get massive speed reduction with this and quiet operation. Also have a look for surplus tape deck motors. These are designed to be very quiet and to have higher torque and less RPM than normal cheap hobby motors.
