Most concrete recycling plants have both primary and secondary crushers. The primary crusher typically reduces the material size down to about 3-4 in. (8-10 cm). The crushed material is then screened and material larger than 3/8 in. (9 mm) is fed into a secondary crusher, which breaks the material to the desired maximum coarse RCA size.

We have jaw crushers that can specialize in recycling applications as well as stone applications. They are designed to work with all of our secondary crushers and screens in our product range.
Often times the secondary crusher is not used and the primary crusher conveys into a screening plant which separates the material into 3 products. Not all jaw crushers are designed to handle hard rock though. In fact, most of the smaller jaw crushers on the market are only designed to crush concrete, block, and brick and not hard rock.
