milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure ...
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 ...
· Re: how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the % volumetric filling of grinding way to make track of mill main drive kW consumption reduction and add makeup .
fabrication of the ball mill, grinding test was conducted with the mill, using limestone as the feed material. This was followed by the particle size analysis of the ground product from the mill in order to determine the performance of the mill. The design results show that the minimum shaft power required to drive the ball mill is horsepower, the length of the mill at a fixed mill ...

media in the mill by looking at the mill grinding efficiency. At that time, it was difficult to acquire a lot of valuable information as robustness in an aggressive environment was not assured. Twenty years later, the Sensomag is able to show this interaction by looking on the pulp position angle and media angle. The Sensomag has been developed to continuously measure both ball load and pulp ...
The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ''H'' from the charge to the shell and the internal mill diameter ''Di''.
L = Internal length of the mill in cms. after lining. To calculate grinding media charge for continuous type ball mill, M = x D2 x L Example To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks. how to calculate grinding media in cement mill.

of other problems in a mill such as a power cut, mechanical problems of transportation or in the water cooling system. Problems of this kind can never really be calculated but they have a detrimental effect on all rolling schedules including stresses in the roll. As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs ...

with grinding media. For the mills with a single compartment we have good results to evaluate the specific charge by measuring the noise produced during the work, or by measuring the energy consumed by the mill. For the mills with many compartments, it is impossible to do that, because grinding media as well as specific charge are different from a compartment to another one. In this situation ...
