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.

New type of crushed sand to replace natural sand in ...

2015-2-4  After VSI crushing, the 0/4 mm crushed sand material was further split in two fractions – 2/4 mm and 0/2 mm. Almost 9 tons of the 0/2 mm fractions were then sent to Metso's air-classification laboratory in Lebanon, Pennsylvania, USA, for controlled removal of filler and alteration of filler grading.
