The whole limestone processing plant includes the crushing machine, grinding mill and beneficiation equipment. These processing machines cooperate with each other to reach the detailed production needs. Make large limestone materials into smaller size for the above applications.
Surface Limestone Mining
The basic elements of surface mining are overburden removal, drilling, blasting and hauling ore to the crushing and processing plant. The selection of surface mining equipment varies with the particular requirements at each operation, including production capacity required, size and shape of the deposit, haul distances, estimated life of the operation, location relative to urban centers, and other social and economic factors. Other factors that must be considered in surface mining are the value of the products produced, location of competitive operations, and environmental and safety requirements associated with a particular deposit.
Underground Limestone Mining
The basic operations in underground mining are drilling, blasting, loading and hauling, scaling and roof bolting. Drilling equipment includes horizontal drills and down hole track drills. This equipment is generally quite different from that used for surface mining and results in much smaller blast holes and a lower volume of rock produced with each blast. Other equipment required in the underground mine includes powder loaders, which are used to blow ammonium nitrate–fuel oil mixtures into the blast holes. Scaling rigs, which are used to remove loose rocks from the ribs and roof of the mine, and roof-bolting equipment may also be required in an underground mine.
