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.

Warping of silicon wafers subjected to back-grinding process

2015-4-1  Wafer warping from a grinding-based thinning process is reportedly related to grinding damage and residual stresses. Assuming a uniform layer of grinding-induced damage, Zhou et al. [5] proposed a mathematical model using the Stoney formula, in which wafer warp was a function of damage depth, residual stress and wafer thickness.

Wafer Backgrinding and Semiconductor Thickness

Wafer backgrinding is the first step in semiconductor packaging, the process of encasing one or more discrete semiconductor devices or integrated circuits (IC) for protection. Known also as wafer thinning or wafer lapping, backgrinding reduces wafer thickness to allow stacking and high-density IC packaging.
