It was with the third concept, that is, controlling the slurry viscosity (rheology) that the greatest initial effects of chemistry on grinding rates were observed. It was on this concept that a very extensive chemical screening …
Slurry rheology affects both the breakage behaviour and the mass transport mechanism in a grinding mill, and hence, influences the milling energy efficiency. The present authors are aware of over 40 references dealing with rheological effects on particle breakage, mass transport, mill power draw, and the use of grinding aids.
This investigation addressed the study of the effects of the slurry's rheological behavior and the state of aggregation and dispersion on wet ultrafine grinding of an iron ore concentrate. Regrinding tests were conducted under different conditions of dispersion (pH 7.3, 8.5 and 10.0) and with the addition of 300 g/t of lime. The increase of pH ...

Investigations have been carried out to evolve a grinding aid useful in grinding a 40% iron-bearing magnetite containing quartz as the major gangue, based on studies conducted with pure magnetite, pure quartz and its synthetic mixture.These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz …
The temperature range is from 50°C to 12°C. It has been shown that in both plant and laboratory environments, the temperature of the grinding circuit slurry has a noticeable effect on grinding and cyclone efficiency. The d size of a hydrocyclone is function of temperature, and the relationship between them is linear.
Compared with the CB grinding slurry, the CIB grinding slurry has a lower DO content and higher Ca ion concentration. Zeta potential results reveal that the Fe species in the CIB grinding reduce the NaOl adsorption on the scheelite surfaces. Finally, the deleterious effect of CIB grinding on the flotation behavior of scheelite is verified by ...
WEIR SLURRY PUMPING MANUAL iv–1 Symbols used The terms slurry and mixture in this Manual are used interchangeably to describe a mix of any loose solids, made up in any proportions and combinations of any particle sizes and any conveying liquid.The subscript w refers to densities and specific gravities of liquids – mostly, but not exclusively, water.
To determine the effect of slurry rheology on industrial grinding performance, 45 surveys were conducted on 16 full-scale grinding mills in five sites. Four operating variables—mill throughput ...
Laboratory results obtained for two different ore samples are consistent with results obtained during a full scale trial. The results provide a basis for analysing the effect of the solids concentration and particle size distribution on the slurry flow properties. Grinding tests were also conducted in an attempt to link the grinding efficiency ...
grind is the single most effective control action influencing the performance of the ore in a flotation plant but in practice, this could mean a reduction of the ore to slimes, which are amenable to flotation. Figure 2 shows the relationships and the effects of the various sub – processes on flotation. The most
The iron ore slurry samples indicated non-Newtonian flow behaviour and fitted quite well with ... energy efficiency on slurry transport depicting the effect of pipe diameter, solids concentration and particle ... were ground in a ball mill with different grinding times and three distinct fine and coarse powder particle size ranges, i.e. <45 m ...
The viscosity of Pulp will affect the grinding rate directly, Elevated temperature, the slurry viscosity reduced. In order to study the effect on the grinding rate of temperature, we did the experiment by only changing the temperature, and three groups of contrast test was carried out. The results show that the grinding rate is improved obviously, when the grinding temperature increases …
The effect of slurry rheology and ball coating characteristics on the abrasive wear of grinding media and the rate of grinding were studied using −10 mesh quartzite in laboratory marked ball wear tests. Pulp viscosity was found to be closely related with both the thickness and physical characteristics of the coating affecting abrasive wear. The packing density of particles at the …
In addition to the bed of grinding balls, and for wet milling specifically, slurry (which is a mixture of ore particles and water in some proportion) is loaded into the mill. Depending on the volume loaded, slurry occupies first the interstices between grinding balls before immersing the bed of balls at rest.
The mineral composition and content are shown in Table 1.According to the measurement result by MLA, the minerals in the ore were mainly magnetite and quartz, accounting for 32.48% and 61.73%, respectively, and their weight was accounted for 94.21% of the total, indicating that the magnetite ores can be basically considered a two-phase mineral …
studied the effect of dry and wet grinding conditions on fineness and shape of particle size distribution of the product in a ball mill and found that effect of variation in ball size responds differently for dry and wet methods. He et al. [17] reported the effect of slurry rheology on the wet ultra-fine grinding of a limestone powder and
Once the ore has been mixed with water and is in a slurry form, it will flow along with the water. The bad side of the water is that it takes up space. The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result. At the other extreme, if not ...
