Naturally occurring concrete aggregates are a mixture of rocks and minerals. Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. Conventional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust.
Aggregate stone crushing operations involve the handling and processing of nonmetallic mineral products for the construction industries. The processing of sand and gravel for a specific market involves the use of different combinations of washers, screens, and classifiers to segregate particle sizes; crushers to reduce oversized material; and storage and loading facilities.
We are professional aggregate stone crusher, and supply various crushing equipment according to customers’ different needs. An entire set of aggregate stone crushing plant usually contains primary crusher (jaw crusher), secondary crusher ( impact crusher, cone crusher), tertiary crusher( VSI crusher), vibrating feeder, vibrating screen, belt conveyor and centrally electric controlling system etc.
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;
