Abstract in view of the midlow grade phosphate rock somewhere in yunnan province first of all study the mechanical properties of ore on the basis of which combine duanshi semi diameter theory formula and crushing statistic mechanics optimized from diameters shapes and proportion of the grinding medias increasing the grinding selectivity only to get selective optimization scheme finally.
Apr 01 in light of this a 30 media filling produces more grinding at any grinding time see table 5 in addition the ore essentially results in total grinding after about 30 min that is to say the product obtained after this grinding time is less than 75 μm a 20 ball filling on the other hand will require a little bit more grinding time to
Are hollow cylinders of large diameters used to grind the iron ore minerals and rock the grinding media to be ground is mixed with iron balls or rods and fed into the mill revolving with axis horizontal and diameter to length ratio 15 to 25 figure 13 2 shows the picture of a rod loaded mill ballloaded mills may be classified as
Ball mill index values for a given ore type mcken verret amp williams on average the rod and ball mill indices are essentially equal but the ratio between the two can be quite variable high rwi bwi ratios indicate competent ores with low ball mill hardness while low ratios represent friable or

Jun 01 grinding balls were selected as shown in table 1 for these reasons firstly it was observed that only balls smaller than 40 mm may show significant effects of media on grinding kinetics in small laboratory mills 20 cm diameters or smaller secondly to mimic the charge motion in industrial mill the ratio of mill cylinder’s diameter to maximum ball size should be at least 6 for instance
Many variables influence the size reduction performance in a mill including the media size shape amp quality the properties of the incoming ore feed the ratio of feed to media and the speed of the mill since grinding media performance is critical to mineral processing operations it’s important to partner with a quality supplier such as
Ratio through a cascade loop for example if the ratio is specified as 2 and cyclone 2 particle size is 30 300 m the control loop will attempt to add water to cyclone 1 sump to achieve a particle size of 15 300 m if the hardness of the ore increases the particle size in the mill discharge from ball mill 1 will increase with
