The Difference Between Ball Mill And Rod Mill Appearance and structure. Although the appearance of ball mills and rod mills are very similar, the proportions of the two cylinder shapes are different. The ratio of the barrel length to the diameter of the ball mill is small, usually equal to 1 or slightly greater than 1; the ratio of the barrel ...

In this example, the OWi of the SAG mill was found to be 30% higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions. In contrast, when the SSE75 …

Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.

SAG mills SAG mills are normally operated with ball loads ranges from 5 – 18 % volumetric filling while RoM ball mills are operated with ball loads ranging between 25 and 40% volumetric filling.

Online SAG Mill Grinding Pulse Measurement and Optimization. Current semi-autogenous grinding (SAG) and ball mills are inherently inefficient, using less than 1 percent of the energy input required for size reduction. Grinding mills also consume tons of steel balls and liners. Proper monitoring and optimization of the operating conditions can ...

When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the …

In all cases, understanding of the transfer size (T 80) between the SAG mill and the ball mill is critical to achieve best economics in a semi-autogenous mill (SAG) grinding plant. T 80 is important to operators because when the SAG energy and the Bond Ball Mill Work Index on SAG ground ore are measured, accurate prediction of future …

To understand the difference between the two, and the challenges that come along the milling process, we first need to gain an understanding of the basics. ... When choosing a mill to fit your business needs, it's important to find the equipment that maximizes efficiency and performance, and you need to know how the equipment will …

mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On

1. Structure. Although the overall structure of autogenous grinding mill and ball mill are similar, but there are differences in details. There are differences in the ratio of the length and width of the barrel between ball mill and AG mill. The large diameter and short length of the barrel of the AG mill reduce the axial segregation of ...

Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.

Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod …

Abstract. The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during …

Difference Between Sag Mill vs Ball Mill mech4study. Oct 12, 2017 Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes.

Tracking the mill performance showed that the mill power consumption decreased from 9.49 to 6.63 kWh/t (a nearly 30% reduction), P80 of the mill product decreased from 611 to 355μm, and the mill ...

The Cadia SAG mill is 40 ft in diameter and the shell of the mill is 22 ft long between flanges. Strain gauges were applied to the Cadia mill at the locations shown in Fig. 2. The gauges were placed in similar locations to those on the Telfer mill but the feed end head gauges were omitted due to access restrictions during relining of the mill.

AG mills can treat both harder or softer ore and scrubbers are for only softer ores. This paper differentiates scrubber and AG mill modelling in a similar way that overflow ball mills and grate ...

Another difference between ball mills and attritor mills is the milling atmosphere. In ball mills, the materials to be ground are placed in a container that is filled with air or an inert gas. On the other hand, attritor mills are operated under a controlled atmosphere. The materials are placed in the mill along with the grinding media and a ...

9.1. In a SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9 respectively. The mill was rotated at 75% of its critical speed when 8 % of the …

Current operational results show that the SAG mill is operating at 5% ball charge level by volume and is delivering a K80 800 micron product as predicted. Power drawn at the pinion is 448 kW, 13.617 kWh/tonne (SAG mill) and 570 kW, 17.325 kWh/tonne (ball mill) when processing 32.9 mtph, for a total of 30.942 kWh/tonne or …

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 grinding action restricts the volume of feed which passes ...
