measure both ball load and pulp slurry positions inside a running mill The main data are provided in terms of toe and shoulder angles Figure 6 The pulp density is an important parameter which influences the grinding efficiency In iron ore for instance a variation of 2 to 3 solid content in the slurry could lead to a
Hydrocyclone parameters and mill sump level are used as constraints in the solution to allow for additional degrees of freedom in adjusting to mill condition while keeping the process stable Ball mills present in the milling configuration can be included in the control solution The density of the slurry feed should be as high as possible but
ρ l = density of liquid without solids lb ft 3 kg m 3 Slurry concentration by weight can be measured by evaporating a known weight of slurry - and measure the weight of dried solids Example - Calculating Slurry Density The density of a slurry where the density of the solids is 2500 kg m 3 the density of the liquid is 1000 kg m 3
Also the uprising velocity in the mill can be controlled by a recycle pump to affect the product size distribution prevent over grinding and reduce the circulating load from the cyclone Final product size is a factor of applied grinding power flow rate and slurry density

Mar 28 2017· Slurry Ball Mill PURPOSE To achieve consistent crystal size from vacuum pan boiling it is important to inject the pan with slurry being micron sized sugar This is best obtained using refined sugar mixed with either absolute alcohol or methylated spirits The mixture is then poured through the spout of the ball mill and ground…
The volume of slurry in a rotary mill has a bearing on the presence of a pool of slurry and therefore on milling efficiency Load behaviour was investigated at different volumes of slurry The insight gained was then used to evaluate the implications of slurry pooling on milling
As you increase the volume of the through put the time that the ore has to react to the grinding media is lessened As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill This water is one- of the main controls that you have over your grind
The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill as well as the slurry that makes up the operating charge Let Jt be the fraction of the mill volume that is occupied
