Introduction to the processing technology system of the jaw crusher production line

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Sand production line

Sand production line processing technologye

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Coal Contour Surface "Strip" Mining - Mine

2001-12-9  The Contour or Bench method of surface or strip mining is usually associated with coal, where a seam or multiple seams are located at a certain elevation or elevations through a mountain or hill. Contour mining allows for the extraction of coal from mountainous areas, where it is not feasible to extract the entire seam, using mountain top removal mining.
