The critical speed is attained when the centrifugal force is that high that all balls are sticking to the mill wall and rotate with the mill. Depending on the application,normal operating speeds of finish grinding cement mills range around 75 % of critical speed. The critical speed is a function of the mill diameter and can be calculated as:

The OK™ mill has been FLSmidth's standard cement VRM since 1993. Since its introduction the OK mill has proven to be the most efficient cement VRM available with the highest reliability and ease of operation. In 2017, FLSmidth introduced the OK raw mill, which is designed with the same proven technology and modular design as the OK cement mill.

Critical Speed The temperatures were taken every thirty (30) mins of the day from 7:30 am to 7:30 pm using the SKL The mill critical speed is calculated using Equation Dual Laser Infrared Thermometer (DLIT).
range. The speed range required by the load can affect both the electrical (thermal) and mechanical design features of the driving motor. Typically speed ranges are specified as ratios such as 10:1 or 4:1. This signifies that the normal operating speed range of the motor, when operating through VFD control, will be between the base speed

This drive train has been well proven over many years of service as a fixed speed drive and offers major benefits over any other arrangement. As mill size increased above approximately 4,476 kW (6,000 hp), the limits of gear technology were reached and it was no longer possible to drive through a single pinion.

Ringgeared mill drive For mills with standard diameters or requiring less than 20 MW (approx.) of power, ringgeared mill drives (RMDs) offer the best solution. Three of the most common drive types for RMDs are low speed motors without a gearbox, high speed motors with a reduction gearbox, and variable speed drives (VSDs).
Now the concrete. I'd recommend a 4" minimum slab of 3,000 psi concrete. So, 5,280 x 10' x .33 = 17,424 cu. ft. OR, 17,424 / 27 = 645 cu. yards. There are lots of mix designs for 3,000 psi concrete. You should order it from the local concrete company because you'll want air entrainment too.
