Comparison of HPGR-Ball Mill and HPGR-Stirred Mill Circuits to the existing AG/SAG Mill-Ball Mill Circuits Abstract In the past 20 years, the energy-efficient comminution technologies, including high pressure grinding rolls (HPGR) and high speed stirred mill, have been developed and adopted in the hard-rock mining operation in order to reduce ... A paper in Minerals Engineering (Comparison of Energy Efficiency Between Ball Mills and Stirred Mills in Coarse Grinding, Vol. 22 (2009) 673-680) reported the energy use of ball mills versus vertical tower and horizontal stirred mills. Both coarse and fine grinding applications were investigated.

Investigations were conducted on whether the greater performance of stirred mills over ball mills in fine grinding can be extended to coarse grinding applications. Four different laboratory ball mills and stirred mills have been tested to grind seven ore samples with feed sizes ranging from 3.35 mm to 150 m. These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills, as demonstrated by Tables 1 and 2. Table 1 Typical Power Intensities of different Grinding Devices Table 1 Power Intensity of Different Grinding Devices Ball Mill is a 5.6m D x 6.4m L 2.6MW Tower Mill

Investigations were conducted on whether the greater performance of stirred mills over ball mills in ne grinding can be extended to coarse grinding applications. Four different laboratory ball mills and stirred mills have been tested to grind seven ore samples with feed sizes ranging from 3.35 mm to 150 lm. Sep 07, 2018 As in other stirred ball mills, grinding occurs by a combination of impingement and rubbing among the grinding balls and grinding balls against screw and mill liners. Tower Mill Circuit. The mill tested was equipped with a 20-hp 1750-rpm motor. Screw rotation was clockwise at 84 rpm.

Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens. Figure 2 - Comparison of the OWi and SSE75 of the SAG and ball mill for 10 A comparison of wear rates of ball mill grinding media. The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill

What are the differences between ball mill and rod mill

significantly increasing grinding efficiency. Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities for grinding Mar 08, 2021 Ball mill and rod mill are suitable for different materials. 1. Selection by materials hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.

Jul 03, 2017 The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ... Our stirred mill and tower mill solutions offer a range of advantages, designed to optimise your milling while solving a number of issues traditionally related to industrial grinding Lower capital expenditures. Shorter lead time than competitors. Simple, containerised shipping. Factory tested, pre-assembled mill components for rapid site erection.

high shear, annular zone located between the outer edges of the For example, it is not currently understood what role media shape rotating screw and the stationary mill shell. plays on the grinding performance within a stirred mill or on the Little work has been done in studying the effect of media shape wear of mill liners. The mill is filled with a suitable grinding media and the area between each disc is essentially an individual grinding chamber. As a result the mill is effectively 8 grinding chambers in series. The media is set in motion by the action of the grinding discs which radially accelerate the media towards the shell.

Dec 31, 1993 A comparison of energy requirements and rheological properties has been carried out for grinding of coal/water slurries produced in high-speed stirred and conventional ball mills. In each case, a linear population balance model using specific energy input as a reduced time variable resulted in a satisfactory description of the size distributions. Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
