granite crusher, limestone crusher, coal crusher, iron ore crusher

The design of a stone crushing production line is usually decided by several factors:
1) raw materials to be crushed
2) The hardness, percentage of Si, moisture percentage of the raw materials
3) The average size of the raw materials before entering into the crushing system
4Requested product sizes, percentage of the sizes, and their usage
5) hour capacity of the crushing line
Limestone crushing plant need limestone crusher equipment. In this process, we usually use jaw crusher, impact crusher, cone crusher, mobile crusher
These machines are used to break limestones into smaller size.
For the Limestone crushing production lines: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph, we here recommend three proposals:
Proposal 1: vibrating feeder +primary jaw crusher +impact crusher +vibrating screen +belt conveying system +control system
Proposal 2: vibrating feeder +primary jaw crusher +fineness jaw crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
Proposal 3: vibrating feeder +primary jaw crusher +Compound cone crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
In the above proposals, the main difference is the secondary crusher: using impact crusher (hammer crushing principle), or using fineness jaw crusher(plate pressing principle), or Compound cone crusher(plate pressing principle).
SBM is a professional ore crusher manufacturer which produce the ore crushers such like marble crusher, granite crusher, limestone crusher, coal crusher, iron ore crusher and so on.
These product series is optimized after adopting domestic and foreign technique. It can process granite, basalt, limestone, etc, which the granularity is not bigger than 120-300 mm and crushing compression strength is not more than 320mp.It features high crushing scale, high crushing efficiency, and it is convenient for maintenance. This cube shaped fineness product is the first-class device used in high grade road surface, railway, water conservancy and electricity industry.

coal crushing plant

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. Coal has very wide using fields in our daily life. SBM crushers and Grinding mills are neccssary equipments in coal processing.

Coal

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly sulphur, hydrogen, oxygen and nitrogen.

Coal Uses

  • Coal as fuel
  • Coking and use of coke
  • Ethanol production
  • Gasification
  • Liquefaction
  • Industrial processes
  • Cultural usage
  • Coal as a traded commodity

Coal Crushing Plant

In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal processing includes coal crushing and coal grinding. Coal crushing plant consist of many types of crushers and Grinding mills. Coal crushers including primary Jaw crusher, secondary Impact crusher and Cone crusher etc. Coal mill include Ball mill, Raymond mill, Vertical mill etc.

Coal Crushing and Grinding Process

If the coal block is bigger than the mill’s max input size, it must be crushed before grinding. The crushing plant common includes Vibrating feeder as feeding material to Jaw crusher, which is as primary Jaw crusher. If need secondary crusher, Cone crusher or Impact crusher can be used. After primary crushing, the coal can be feeding to Ball mill to fine grinding. To increase Ball mill effective, the vertical coal mill or coarse powder mill can be setted before Ball mill as pre-grinding.
