Bluestone is one of the most widely distributed gray or gray sedimentary rocks (about 15% of the lithosphere) in the sea lake basin. It is the most important component of carbonate rocks. Bluestone is the raw material of lime. Besides lime, Bluestone is also used as stone and sand by stone factory. As a component of cement, gravel is a necessity for building houses. The main component of bluestone is calcium carbonate, no pollution and no radiation, so bluestone made out of stone tablets, slabs, stone carvings are also green products.

Bluestone Processing technology

The bluestone texture is relatively soft. After mining, jaw crusher and impact crusher are often used to crush bluestone. With the advantages of large crushing ratio and stable operation of equipment, they are favored by users. The process of bluestone crushing production line: the stone is blasted down from the hill, the stone less than 1020 mm is fed into the vibrating feeder by the dump truck, the stone is evenly fed into the jaw crusher, the first section of the stone is crushed by the jaw crusher, and the stone crushed out from the jaw crusher is about 150mm-300mm, through the vibrating feeder. The material is sent to the impact crusher or cone crusher for the secondary crushing. The material is classified and screened through a circular vibrating screen. The material larger than the finished product is returned to the impact or cone crusher, and the finished product is transported to the finished product area by a belt conveyor. The bluestone crusher manufactured by vanguard Machinery is designed and manufactured in combination with the world's top technology. It has advanced equipment and technology, stable operation, high crushing ratio, uniform grain size, simple structure, reliable performance, easy maintenance and economical operation. Wear-resistant parts are all made of excellent manganese steel castings, combined with advanced technology and customer feedback, on the basis of years of crusher industry, the company has led the development and production of large and medium-scale bluestone crushers, continuous innovation and improvement, in the large and medium-scale crusher market, has been in an absolute leading level.
The aggregate processed by crushing machine sand is widely used in highway, high-speed railway, rural highway, construction sand and other fields. Bluestone is an ideal material for the construction industry. Bluestone is mainly composed of shallow gray thick layer of oolitic rock and thick layer of oolitic rock with leopard limestone. It has the advantages of water absorption, heat absorption, heat preservation, heat insulation, anti-slip, moisture-proof, cold resistance, anti-freezing and so on. It can be used in municipal construction, landscaping, unit and family decoration.

Application fields Through the deep processing, Bluestone can be widely used in the following industries.
