Get PriceThe mill used for this comparison is a 4.4meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 per hour.
Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages. Motors considered are the
We can provide all elements of a mill drive system as a fully optimised solution to suit your process exactly, or individual mill drive gearboxes, girth gears, pinions and couplings as required. Designed to deliver exceptional levels of performance and value, David Brown Santasalo ball mill drives are optimised for primary and secondary
21 CONCLUSIONS Continued In the present work, equations were also derived, giving zthe ballmill power drawP as a function of its dimensions internal mill diameter D and length L, zthe ballmill power drawP as a function of the feed D f mm and the product size d mm, the Bond work index w i kWhshort ton and the mill throughput T short tonh, zthe ballmill dimensions D and L, when
The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables the old fashion way.
Please find below two calculators for sizing mills using the Bond and Rowland methods Ball mill sizing Calculator for ball mills in a single stage circuit. Rod ball mill sizing Calculator for rod mills as first stage of the circuit and ball mills as second stage of the circuit.
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
In Grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 cost you much in recovery andor mill liner wear and

The Ball Mill Finish Calculator can be used when an end mill with a full radius a ball mill is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop, amd the scallop will be determined by the stepover distance
