Cobble is a silicate with hard, wear-resistant, and stable feature and has rounded appearance after impacting and brushing by water and other materials. It mainly consists of silica with the color of black, white, yellow, red, dark green, and graphite. As an important industrial material, it is widely used in water conservancy, highway, railway, bridge, high building, and other industries for concrete making. Also cobble has rich resource, low cost, and high value.
Jaw crusher can crush high hardness materials of cobble, granite, and other materials by crushing and squeezing. Through it has high crushing ratio and production capacity, it cannot crush plastic material. Dingli’s jaw crusher has reasonable price, reliable quality, many successful cases, and low investment cost.
There are two crushers for primary and secondary crushing and then sand maker for sand making.
First stage
Bulk cobble is firstly crushed by jaw crusher and then screened for secondary crushing.
Second stage
After secondary crushing with crusher, smaller material can be used for sand making by sand maker.
Third stage
Crushed cobble is firstly sent into sand maker for material shaping and then washed by sand washer for clean and qualified material.
Fourth stage
Finished cobble should lastly be stored.
As the rich and important natural resource in China, cobble has a wide range of application of public building, villa, garden architecture, road construction, rockery, and other constructions. Also it has rich resource, low cost, and high application value.
