Cement grinding plant is the final stage in the production of cement, which is separated from the finished cement production units. It mixes cement clinker with other certain amount of mixed materials for grinding, and then produces the finished cement.
In this plant, gold ore is mainly natural gold among the ore to be processed, but it is mostly distributed in the crack of poisonous sand, pyrrhotite and quartz crystal gap, which significantly improves the processing difficulty of the gold ore. The custo
