Limestone, one of the largest produced crushed rock, is a sedimentary rock composed mostly of the mineral calcite and comprising about 20 percent of the earth’s sedimentary crust. This mineral is a basic building block of the construction industry and the chief material from which aggregate, cement, lime, and building stone are made. For the purposes of this report, limestone will be used as a sample for crushed rock.
How Is Limestone Mined? Limestone crusher plant
Limestone is mined in various stages. First the top soil is Loder or shoveled out till you reach the hard rock. Then is cut into block any where from 18 tons to 3 tons. There are 3 grades, top ledge, bottom ledge and middle. There is a soft line in the middle portion that also is the fossil line. The blades that custom cut for the basic user is made out of diamonds on a heavy rubber bands.
Limestone Mining Process , Crushing equipment
Limestone mining process is also called limestone quarrying process. Extraction (more commonly referred to as quarrying) consists of removing blocks or pieces of stone from an identified and unearthed geologic deposit. Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself—such as density, fracturing/bedding planes, and depth—financial considerations, and the site owner’s preference. Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage.
Limestone Crushing Plant
Limestone crushing plant for sale by DM mainly includes jaw crusher, impact crusher, and single stage fine crusher. DM series Turbo crusher is generally used as the primary crushing machine. Turbo crusher is designed to crush large size limestone into small size limestone with large crushing ration and high productivity. TURBO SERIES and impact crusher can finely crush the limestone for secondary crushing. If the processing capacity is comparative small, single stage fine crusher or tertiary crusher is suitable to be used as the single limestone crushing machine.
