Mar 15, 2003· In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm.

Coffee mills (sometimes also referred to as electric blade grinders, whirly grinders, or propeller grinders) chop up coffee beans into smaller particles as opposed to grinding them. They do this via propeller shaped stainless-steel blades revolving at very high speed (20,000 – 30,000 rpm). You control the fineness of the coffee grind by how long you let the blades chop up the beans.
In the cement grinding system, the grinding fineness is an important indicator to determine the level of the process, because the size of the grinding affects the product quality and power consumption of the mill, and it is also related to the subsequent work, so it is crucial. important.
