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.

[PDF] GRAVITY CONCENTRATION OF SUDANESE

The main raw materials for chromium metal is chromite. Geologically, chromite deposits are associated, by their nature of formation, with specific gangue minerals such as serpentine, olivine, and chlorite. These associated minerals are of lower densities than chromite. This criterion of density difference between chromite and the associated minerals suggests the use of gravity separation ...

Slags coming from stainless steel (SS) and ferrochromium (FeCr) production generally contain between 1 and 10% Cr, mostly present in entrapped metallic particles (Fe–Cr alloys) and in spinel structures. To recover Cr from these slags, magnetic and gravity separation techniques were tested for up-concentrating Cr in a fraction for further processing.
