Grinding of mineral mixtures in high-pressure grinding rolls
For grinding such heterogeneous feed in large tonnages, ... It appears that differences in hardness of the components in the mixed feed may be more important in high-pressure roll mill grinding than differences in grindability. Although the grindability of the two materials differs only by a factor of two, the hardness of the two components ...
Grinding of mineral mixtures in high-pressure grinding rolls
The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high temperatures.

Predicting the overall specific energy requirement of crushing, high
High-Pressure Grinding Rolls (HPGR), as a modified type of roll crushers, could intensively reduce the energy consumptions in the mineral processing comminution units. However, several problems counted for their operational modeling, especially in the industrial scales.
Comminution of Minerals on a Laboratory-size Choke-fed High-Pressure
Experimental data on the production of fines as a function of specific grinding energy consumption show that in general the energy utilisation in a choke fed high-pressure roll mill is higher than in a ball mill, but lower than in the single-particle mode of comminution under slow compressive loading. There is some evidence to suggest that …
