A. First-order plots for batch dry grinding of feeds of 16 × 20, 35 × 45, 45 × 60 mesh iron ore. B. First-order plot for dry grinding of 4 × 6 mesh (oversized particles) iron ore: effective S ...
The screen panel is recognised as the high wear item in the SAG mill trommel. While polyurethane screen media is often specified for ball mill trommels, Multotec has developed a range of compression moulded rubber compounds that have achieved excellent results in high wear SAG mill duties.
An iron ore concentrate sample was ground separately in a pilot-scale HPGR mill in multiple passes and a dry open-circuit ball mill to increase the specific surface area of particles. The effects of grinding mechanisms on generating pellet feed were assessed and pellets and DRIs were produced.
The advantage of the grid type ball mill is that the ore discharge speed is fast, it can reduce the over-crushing of ore, and at the same time it can increase the output per unit volume. 1. Large row of …
