The Difficulty of Ore Crushing and the Choice of Crushing Method
The strength of external resistance force appeared in the ore crushing becomes the difficulty in the process of ore crushing. It is the standard of ore crushability, which mainly depending on the ore structure characteristics and mineral crystal habit.
The main factors influencing the degree of ore crushing is ore hardness. Ore crushing methods are mainly based on the ore physical and mechanical properties, feeding granularity of ore blocks and the required crushing ratio.
Mineral ore is usually a symbiont of a variety of minerals with different properties. The compressive strength is the largest, following is bending strength, and wear resistance, extension strength is the smallest. Based on the above mechanical features, choosing the proper crushing method can obtain the effective crushing result.
