Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can

Taper Angle Calculation
Taper Degree Calculator. Taper Degree is the central angle of the taper measured in degrees. It can be calculated from the taper % or it can be calculated with the number of the different type of tapers. For instance, a #2 morse taper has an angle of 2.86133 degrees. Use this online calculator

Floating Ball Valves
The design of BFE ball valves is based on the"ﬂ oating ball" principle which allows the ball to turn freely between the ball seals. A positive seal is attained by ﬂ uid pressure acting on the upstream surface of the ball and producing a constant uniform contact between the downstream ball seal and the ball.

Process Sigma and DPMO Calculator
In our example, if there had been 7 defects (3 bearings for diameter and weight; 1 for roundness) out of 2,000 bearings, the calculation would be 1,000,000 X 7 / (2,000 X 4) = 7,000,000/8,000 = 875. The Value of DPMO. Both Defective PPM and DPMO are indicators for the effectiveness of a process.

Bearing Life Calculation
Not only must our industrial class bearings provide long inservice life from a rolling fatigue criterion, but they must also hold together structurally from impacts, overloads and occasional high speed excursions. The design of every heavy duty bearing has been optimized to this end, including our large bore bearings. Ball Bearings
