1.2 Calculating the silo discharge diameter with the method of Jenicke. The flow of powder in a hopper is linked to 3 properties : The powder internal friction : how easy the powder particle can move from each other
The ball mills are operated at a ball charge volume of 30–32 and 78.5 critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed.

The mill discharge from ball mill 1 will increase With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase This will decrease the ratio and hence the control loop will add more water to keep the ratio constant However the amount of slurry reporting as fresh feed to the second milling circuit will increase.
Calculating Mill Discharge; CHAPTER 6 WASTEWATER TREATMENT AND DISCHARGE. practices only.1 Treatment and discharge systems can sharply differ between countries. ... To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08.
pump discharge. Pump operation basics Best Efficiency Point (BEP), the flow rate where a pump has its highest efficiency, is a key factor to assess whether a pump is being operated properly. Few pumps operate at their exact BEP all of the time,
mill speed (see Graph 2) as the curves are mostly overlapping. Density These tests were done with a ∅0.82 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids. The data is summarized in Table III.
Calculate Media Charge In A Ball Mill Xls. EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS media ie 306 mm 388 mm and 492 mm Then two ball mixtures were successively considered For grate discharge mills the charge should occupy about 50 of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as …
Calculating Mill Discharge The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and …
The discharge consists of openings in the shell into which bushings with holes of the desired size are inserted. On the outside of the mill, flanges are used to attach a stationary discharge hopper to prevent pulp splash or too much dust.
1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and …

There is currently no accepted pilot test procedure for measuring discharge and product size distributions in AG/SAG mills. The existing models and understanding of grate discharge and classification are known to be flawed and have been identified as one of the key limitations in AG/SAG modelling.
M = tonnage of ore in mill discharge and Ds, Do, and Dm are the liquid-to-solid ratios of the sand, overflow, and classifier feed at the points where they leave or enter the classifier. Then circulating load ratio = (Do-Dm)/ (Dm-Ds) (8) And circulating load tonnage = F (Do-Dm)/ (Dm-Ds) (9)
