Recycling of concrete pavement is a relatively simple process. It involves breaking, removing and crushing concrete from an existing pavement into a material with a specified size and quality. Crushed concrete may be reused as an aggregate in new Portland cement concrete or any other structural layer. Generally it is combined with a virgin aggregate when used in new concrete. However, recycled concrete is more often used as aggregate in a sub-base layer.

Before crushing materials, need hopper and feeder that can move the rocks to crushing machine, in here, we recommend you use Hopper, and vibrating feeder, move the materials to jaw crusher , then come into the semi-product piles, then need vibrating feeder, along the flow chart, come to the cone crusher, then use vibrating screen, the ouput size of materials may be 40mm, the to the VSI sand making machine, the last machine is vibrating screen, also can use screening plant, the output size can screened 0-5mm, 5-10mm, 10-20mm, 20-40mm.

Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
