Advantages of coarse wet ball mill applications using the vertimill

vertical ball mill can grind coarse and hard granular the vertical ball mill has stable performance, supports dry and wet grinding, and has unique performance for coarse and thickened materials. vertical ball mill can be widely used for dispersion and grinding of solid or powder materials in paint, medicine, building materials, chemical industry and other industries. improving overall concentrator performance with stirred millingcoarse balls for coarse gri nding in ball mills and small grinding media for final gr inding stage in vertimill®. mass recovery of concentrate removed from grinding comparison of energy efficiency between ball mills and jun 01, 2009 · the work using a vertical shaft stirred mill compared with bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to p 80 less than 100 m. vertimill® grinding mills &stirred media detritor by aug 29, 2013 · mill type. ball mill. vertimill® smd. 100000. 10000. 1000. 100. 10. microns. 1. ball mills and stirred mills are applied across a wide range of applications, but for each ore there is optimum douglas batista mazzinghy et al. miningthe main objective of this work is proposing a way to simulate the industrial vertimill using the population balance model, normally used to simulate ball mills. the simula tions were based on the selection and breakage functions determined from the labora tory tests using a batch ball mill. the simulations were performed using a vertimill vertical mill vertimill® type wb corporation wet in fact, in the same application a vertimill® has 50% less footprint than a ball mill. lower operating cost vertimill® is an energy efficient grinding machine. they tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns. this provides up to a 40% higher energy efficiency. (pdf) design and operation of vertimill® for secondary grindinga vertimill to grind the coarse cyclones was considered to be safer for the vertimill application as it the possibility of improving the capacity of ball mill circuits by improving applications of vertimill in grinding circuits*(hematite) concentrate. it also presents data that highlights the viability of using the vertimill as a secondary grinding stage processing a product from sag mills or high pressure grinding rolls. figure 2: vertimill applications . 1.2 existing vertimill applications in coarse applications grinding / mces official distributor the rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/coke, and other materials for both wet and dry applications. the rod mill accepts feed ore as coarse as 1 1/2 top size although better performance is obtained by restricting ore feed size to 3/4. vertimill pilot scale tests simulated by perfect mixing jul 01, 2014 · the screw agitator lifts the media and circulates it throughout the mill. the higher efficiency of the vertimill is due to the higher frequency of lower energy impacts and, by the same token, smaller frequency of higher energy impacts when compared to conventional ball mills . fig. 1 shows the vertimill. download : download fullsize image
