COMPARISON OF HPGR - BALL MILL AND HPGR - STIRRED MILL ...

In order to make a proper energy comparison of the AG/SAG mill - ball mill circuits and the HPGR - ball mill circuit, the ball mill circuit energy requirements were calculated via the “phantom cyclone” / Bond method (Napier-Munn et al., 1996; Doll et al., 2010).

Ball Mills vs Rod Mills

03/07/2017  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, and the path of the material is more confined. This

What's the Difference Between SAG Mill and Ball

Ball mills are fine grinders, have horizontal ball mill and vertical ball mill, their cylinders are partially filled with steel balls, manganese balls, or ceramic balls. The material is ground to the required fineness by rotating the cylinder causing friction and impact. The internal machinery of the ball mill grinds the material into powder and continues to rotate if extremely high precision and precision is required.

Comparison between Rod Mill and Ball Mill - ore

The reason is that, when the grinding rod and the grinding ball are in the same weight, the superficial area of grinding rod is much smaller than the grinding ball, the production capability and high efficiency of rod mill will lower than ball mill in the secondary grinding stage. 3. Sometimes, rod mill can be used for fine crushing instead of the short head cone crusher. If the ore is not too hard, crushing the ore from

How HPGRs compare to conventional milling

As a result, ball mills produce a rather wide particle-size distribution (PSD), requiring additional work downstream, while rod mills achieve a lower PSD but produce a coarser product. By comparison the inter-particle compression in a High Pressure Grinding Roll has a more even effect on the entire feed, resulting in a high ratio of fines without the wide PSD.

Ball Mill - an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight. Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from

Energy and Cost Comparisons of HPGR-based

The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWh/mt, but for the SABC circuit it only used an extra 1.8 kWh/mt. The reported SABC circuit power for the 160 μm grind size was based on actual site data. JKSimMet was used to fit a model to site DCS data. Thus, there was considerable scope to reduce the ball-mill power consumption by using smaller ball-mill grinding

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse ...
