In addition lifter spacing and lifter height will have an effect on mill performance and liner wear rate. On fully autogenous mills featuring reversible rotation significant success has been achieved by the use of Ni-hard wear plates with replaceable "clamp type" lifters of chrome-molybdenum steel, or one of the "tough" iron alloys.

2006). Illustrations of some current shell lifter-liner designs are shown in Fig. 3 (traditional "HiLo" plate and lifter), Fig. 4 (integral "HiHi" top-hat type) and Fig. 5 (a "HiLo" from-new type). Current shell lifter designs commonly adopt large face angles, typically 22° but up to 35° with high shell lifters, to

Informed SAG mill designers understand geometries importance in lifter/liner designs and mill comminution efficiency, power draw, and wear life performance, noting a trend to larger lifters at greater pitch, which can impose higher forces on lifter systems and result in higher wear rates.

helps understand charge motion in SAG mills for the given liner designs and lifters, ball size and rock properties, and mill operating conditions. Based on the success of the 2-D model of the SAG mill, the 3-D model in DEM was developed. These types of models could help study charge motion, power draw, liners wear, and energy draft

A list of the primary types of liners is given, with comments on their application, advantages and disadvantages: 1. Solid Liners - These have an integral lifter and liner, as shown in Figure 1. These have fewer ... material used for SAG mill liners. There are a number of variations with either different

The Poly-Met liner includes Poly-Met shell plates and lifter bars; feed and discharge head end plates, lifter bars, pulp lifters and grate plates, The Poly-Met liner is made of highly wear-resistant rubber and alloyed steel such as the highly wear Sweden HARDOX steel plate under high temperature and pressure. 2. Physical Properties: Property.

and improvement in mill capacity. Implementation of the new design in the SAG mill was carried out, resulting in increase in daily throug hput from 6 to 12%. Further, the time spent in liner ...

The number of lifters in the liner of ball mills and the mill rotation speed are among the most significant factors affecting the behavior of grinding charge (balls) and their motion trajectory, and consequently, the comminution mechanism in these mills. In this research, in order to find a suitable range for the number of lifters in the liner of ball mills, the DEM method is utilized.
