to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick's constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E = K K f c ln(L 1 /L 2) (11.2) Equation (11.2) is a statement of Kick's Law.

In fact, reduction ratios as low as 6:1 are now considered perfectly alright for many applications, thanks in part to the improved casting practices today. Therefore, better is the casting practice, accordingly the reduction ratios can vary. In case of hot forged bars the reduction ratio of 4:1 is considered as a standard and in case of higher ...
The common four-pole generator together with 50 or 60 Hz grid frequency determines a fixed generator speed, while the corresponding rotor speed is determined by a fixed gearbox ratio. If, for example, the generator rated speed in a 50 Hz grid network is 1500 rpm, and the gearbox step-up ratio i = 1:75, the corresponding rotor speed is 20 rpm.
MVR vertical mill with conventional drive: economical solution for small to medium output rates.

The climbing power is 18% and the maximum speed 88 km/h. The drive designed in this way comes with a differential of up to i=5.1, which the summation gearbox additionally offers a reduction of i=2.7. The max. torque is thus a total of up to 30,500 Nm. With two inverters of the type VP600-18W268, ARADEX also offers suitable electronics for this ...
The planetary gear set is the device that produces different gear ratios through the same set of gears. Any planetary gearset has three main components: · The sun gear. · The planet gears and the planet gears' carrier. · The ring gear. Each of these three components can be the input, the output or can be held stationary.
The first reduction stage in the gear unit, the bevel stage, redirects the horizontal rotation into the vertical axes of the mill and is followed by a planetary gear stage, according to your torque and ratio requirements. We use the ring gear of the planetary stage directly as part of the casing in the larger series of our MAAG® GEAR gear units.
