Spindle Speed. A fixed, center spindle delivers spindle speeds from 15,000 to 50,000 rpm. It is held by the machining center spindle so programming adjustments are minimal, requiring only a Z-axis offset. In general, 8,000 rpm is considered a minimum ante for the rotational aspect of high speed machining.

To start, find the rotational speed of your drive gear. In most gear calculations, this is given in rotations per minute (RPM), though other units of velocity will also work. For example, let's say that in the example gear train above with a seven-toothed driver gear and a 30-toothed driven gear, the drive gear is rotating at 130 RPMs. With ...

And coming to Motor capacity, we have to consider approx. 30% excess to the required capacity, so the motor capacity will be 8.6 * 1.3 = 11.18 KW ~11.5 KW = 15.4 HP ~16 HP. Usually a motor will have an RPM of ~1475, so to match the anchor RPM to 48, Gear box should have an ratio of 1475 / 48 = 30.75.

Power = Torque x radian speed 2 x pi x rpm kW = kNm x -----60 rpm of belt-driving drum or rpm of drive gearbox ratio = rpm driving drum / rpm drive etc. But, may be you are referring to the belt conveyor design, which is much more complicated. Then it is better to orentate yourself with literature, experts and manufacturers. success

to high and the mill be filled up with material and trip on vibration, because the mill fan dont have the capacity to transport material out of the mill. If the feed rate is to low will the mill emptied out and trip on vibration, due to low grinding bed. The feed rate depends on the applied grinding pressure and the grind ability of the material.
