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 machinemade 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, highspeed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Microwaveassisted beneficiation of recycled concrete ...
201181 By fine tuning the process to avoid excessive heating, because of the slower heating rate and significantly higher tensile strength of natural aggregates compared to mortar, the respective stresses developed in the natural aggregates at the time of mortar delamination and pulverization are significantly lower than the aggregate’s tensile strength. Therefore, the RCA beneficiation process may be easily optimized to avoid damage to the integrity of natural aggregates,

2021122 Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected.

In this study, it was found that when recycled aggregates from high strength concrete were used, the compressive strength can be similar or even higher than for comparable normal. However, there are indication that the bond strength of natural aggregate were 9.4%–21.3% higher than RCA concrete (Pandurangan et al., 2016). Such contradictions in results may have attributed to the type of bond test
