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.

Reverse flotation separation of hematite from quartz ...

2019-8-1  The effect of magnetite as a magnetic seed on the flotation separation of fine hematite and quartz was studied by reverse micro-flotation and sedimentation. The results demonstrate that fine magnetite could selectively report to the pulp product with hematite particles, forming aggregates that avoided attachment to quartz particle surfaces.

Separation of ultra-fine hematite and quartz particles ...

2021-4-1  In this study, an asynchronous flocculation method was explored in the flotation separation of mixtures of ultra-fine hematite (d 50 = 7.2 µm) and ultra-fine quartz (d 50 = 1.6 µm) using polyethylene oxide (PEO) and starch as the flocculant of quartz and hematite, respectively. Dodecylamine acetate was used as a collector for quartz in the tested reverse flotation scheme.
