The manufactured sand made of river pebble materials has a wide applications in cement concrete, asphalt concrete and various soil cement (stabilized soil) materials and other road, tunnel, bridge and culvert engineering projects. With the exhaustion of natural sand and the environment problems caused by natural sand exploitation are more and more severe, manufacturing high quality sand to replace the natural sand has become one consensus all over the world.
Camelway river pebble production line can adjust the equipment configuration according to the specific production technology and customer’s various demand.
The main chemical element of river pebble is silicon dioxide, and then are slight iron oxide and trace element like magnesium, copper, aluminum, magnesium,etc.It has the advantages of high rigidity, high compressive strength, high abrasion and corrosion resistance and it is one ideal type of building materials.
The crushing process of large size river pebbles can borrow the granite and basalt crushing experience that is firstly adopting jaw crusher for primary crushing; The smaller size materials should adopt pre-screening process to reduce the cost.
The crushed materials will be transferred to the cone crusher for secondary crushing, the semi-product size over 40㎜ will be conveyed back to the cone crusher for crushing again to form a closed crushing circuit, and the particle size between 5-40㎜ will be transferred to the VSI crusher to produce manufactured sand, and the particle size below 5㎜ will be transferred to the end product storage bins. As for the VSI crusher stage, it is like the cone crusher stage, the materials screened by the vibrating screen also have 3 different disposal methods. Our customer can also choose to adopt sand washing machine for more clean manufactured sand optionally.
The Camelway VSI crusher equipped at the production line is one new style sand maker, adopts international advanced crushing and sand making technology, has the features of high crushing productivity, simple structure, easy installation and maintenance, low operation cost, good grain shape. Owing to the better grain shape, it is often used as sand shaping machine in many stone crushing and sand making production lines.
