Rock Mining
Rock is a sedimentary rock composed largely of calcite, calcium carbonate (CaCO3). Rock often contains variable amounts of silica or siliceous skeletal fragment, as well as varying amounts of clay, silt and sand sized terrestrial detritus carried in by rivers.
Most crushed stone is rock and dolomite. It is used mostly for construction purposes, although much of it is also used in shoreline protection. In construction, crushed rock is used as an aggregate in cement mixes. The rock binds the mix together when it hardens. Almost 60% of all crushed rock is used as aggregate in highway cement and asphalt. All crushed rock in Michigan is mined in open quarries. Drilling and blasting are necessary.

Rock Mining equipment
Rock mining equipments are used widely in rock crushing industry. Many rock crushing plant includes rock crusher and rock mill or other related rock crushing equipments. Rock mining has important position in modern construction and road building industry because rock is the most widely used stone or rock. Hongxing is a professional rock mining equipments supplier and can supply you many rock mining machines such as rock mining crusher, rock mining mill, rock mining feeder and so on.
Hongxing crusher and grinding mill in processing rock.
There are two processes from the raw rock to final product-crushing process and grinding process.
If the raw rock is bigger than the input size of your grinding mill, it should be crushed firstly. The proposed rock crusher is Hongxing impact crusher, which features reasonable structure, high productivity, easy operation and maintenance and safe performance. It can crush the material whose pressure resistance strength is under 350Mpa. The rock from the mines is conveyed to the crusher through conveyor. Crusher reduces the size of the rock from 1m to –25 mm size. The crushed rock will be sent by a belt conveyer to vibrating screen becoming final products or to grinding mill to fine grind. In order to control the emissions from the crusher, a suitable bag filter system will be provided.
If the raw rock is small enough and can be directly grinded by grinding mill, it can be grinded directly. The proposed rock grinding mill is Hongxing MTW series mill or high pressure mill (raymond mill). If you need high fineness, you can choose Hongxing Super-micro mill, which features high capacity, low consumption, high fineness, flexible adjustment and trustworthy security.
Here are a customer cases for reference, which consists of a PE impact crusher, a high pressure mill, some vibrating screens, some belt conveyors and other auxiliary equipments. It locations at north of Ethiopia and its contracted value of all equipments is at USD $21.87 million. It can process 200t raw rock to different size final products every day.
As the professional manufacturer of complete sets of mining machinery, such as ball mills,Cement machinery,Magnetic separator,concentrator table, Henan Hongxing is always doing the best in products and service.
