Milling Parameters

The end mill speed is calculated with the following formula n rpm = vc m/min 1000 / 3.14 ø d1 mm Example calculation vc = 500 m/min selected from chart d = ø 8 mm 19904 rpm = 500 1000 / 3.14 8 If the maximum speed of the milling motor is lower than the calculated value the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation.

Hammer mills an engineering overview

3.2 Shaft speed The 2nd key design and operational aspect for a hammer mill is the rotation speed As the milling principle is based on the energy of the impact the higher the speed the finer the product can be expected as the particles will heat the hammer at high speed but also be sent against each other or against the screen at high speed.
