The main chemical composition is silica, followed by a small amount of iron oxide and trace of manganese, copper, aluminum, magnesium and elements and compounds. They itself has different pigment, such as the s for iron, blue person for copper, purple person for manganese, yellow translucent for silica gel chalcedony, jade color with green mineral, etc. Domestic main origin of extend from nanjing, jiangsu area, middle and lower reaches of Yangtze river is abundant resources, much performance is pebbles deposit shape.

VSI series centrifugal impact crusher is in my company many years development, the development, the production of mining machinery basis, absorbs the domestic and foreign similar products advanced technology development with the international advanced level of a new generation of energy saving, high efficiency crusher, and its performance in pebbles processing process has excellent quality.Sand making equipments mainly include impact crusher, jaw crusher, hammer crusher, cone crusher,roll crusher and vibrating feeder,etc.

As a system of sand pebbles main raw material, in industrial field plays an irreplaceable role. Public buildings, villas, courtyard architecture, paved roads are all dependent on the shadow of pebbles. It not only have the hard quality, bright colours, and compressive resistant to wear and corrosion. Hongxing crusher enterprise many clients with pebbles do raw material, after crushing successful application in many fields.

Hongxing VSI impact crusher is ideal equipment for processing pebbles. VSI centrifugal impact crusher is the use of high speed movement of materials by mutual crushing and material of the friction between the and crushing. Centrifugal impact crusher can not only gravel, but also can shaping of stones. According to the material feeding way, centrifugal impact crusher work forms can be divided into completely center feed and center feed with organ fall feed; According to the material of compressive strength, abrasion resistance, centrifugal impact crusher work forms can be divided into stone hit stone and stone the iron is hot two broken form. So centrifugal impact crusher work forms can be divided into four kinds: center feed with organ fall feed stone hit stone and stone the iron is hot, completely center feed stone hit stone and stone the iron is hot.
