vertical hydraulic mining

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.

Stone production line

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.

2016-10-1  Vertical hydraulic transport systems for deep ocean mining have lengths up to a few kilometers from seafloor to sea surface. Typical ratios of particle diameter d over riser diameter D are d / D = O (10 − 1), and the feeding of the riser is irregular. These conditions make the vertical transport operation susceptible to propagating density waves which is detrimental for the transport process.
