Scale Up in Sizing for Grinding Mills. Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and .

(for density correction) effective density of the mill charge Output. The model output is the "US horsepower per foot of mill length" where the power is measured at the mill shell. Multiplying this output by the mill effective grinding length and converting the result to modern units of power results in the mill power draw at the shell in

The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it .

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

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 cost you much in recovery and/or mill liner wear and tear.

Ball Mill Grinding Capacity Calculator Ball Mill Motor/Power Sizing Calculation Ball Mill Design/Sizing Calculator The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to (HPhr/short ton = 1.34 kWh/short ton) Wi ...

Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.

Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.

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.

The power calculated on using equation 1, (Bond, 1961; Rowland and Kjos, 1978), relates to: 1) Rod milling – a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.
