Figure 2—HPGR ball-mill circuit To determine whether the novel HPGR-stirred mill circuit arrangement could achieve energy savings in comparison to conventional SAG mill-based circuits a pilot-scale study was conducted to compare the energy requirements of the existing circuit at the Huckleberry mine to two alternative circuits an HPGR-ball mill circuit and a novel HPGR-stirred mill circuit
Stirred mills are primarily used for fine and ultra-fine grinding They dominate these grinding applications because greater stress intensity can be delivered in stirred mills and they can achieve better energy efficiency than ball mills in fine and ultra-fine grinding
The grinding efficiency of ball mill is low the treatment capacity is low the production energy consumption is high the product fineness is unstable and so on which are the problems that most concentrators will encounterow to effectively improve the grinding efficiency of ball mill Comparison Of Grinding Energy Efficiency Between E And
Material is fed into the gap between the rolls and the crushed material leaves as a compacted cake The energy consumption is 2 5–3 5 kWh/t and about 10 kWh/t when recycling of the material is used The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill
The vertical roller mill allows a large amount of air to be passed so the drying capacity is large the material in the grinding is in a suspended state which increases the contact area between the material and the airflow and the heat exchange condition is good so the drying efficiency is high (When the ball mill grinds the wet material
