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.

DEVELOPMENT OF ACCURATE METAL PRODUCTION

2013-10-30  There has been a concerted effort in the precious metal heap leaching industry to diminish the average heap irrigation rate. Many gold and silver properties irrigate the heap at a higher flow rate (for example, 12 L/hr/m2) for an initial 14 to 21 day leaching period in order to quickly recover the most amenable portion of the precious metal content of the ore. After this time has passed, a lower irrigation rate (sometimes as low as 1.2 L/hr/m2) is then utilized for the remainder of the leach cycle. This procedure tends to maximize the precious metal
