Bluestone is one of the most widely distributed gray or gray white sedimentary rock generated in the sea and lake basin (about 15% of the lithosphere), water absorption rate ≤0.75%, bending strength ≥ 10.0Mpa, glossiness about 60, density 2800kg/m3, and the composition of marble is also limestone, so bluestone is also the category of marble. Bluestone is the raw material of lime. In addition to lime and bluestone, bluestone is also mined into pebble and sand by stone factories. Gravel as an ingredient of cement, sand has become a necessity for building houses. Bluestone is mainly composed of calcium carbonate, no pollution and no radiation, so bluestone stone steles, slates, stone carvings are also green products. so the steles, slates, stone carvings made out of limestone are also green products.
The main equipment of limestone sand making production line includes vibrating feeder, jaw crusher, (impact crusher is optional), high efficiency sand making machine, vibrating screen, centralized electric control and belt conveyor, etc. Our bluestone sand making machine production line fully embodies the scientific, realistic, reasonable, effective and applicable design. Large processing capacity, low abrasion wear, and low operation cost are its remarkable features. The limestone sand making machine produced by Yusheng Machinery attracts many customers to investigate because of its high sand making efficiency, high wear resistance of the equipment, superior performance and affordable price.
Bluestone texture is relatively soft, after mining, commonly used jaw crusher plus impact crusher for crushing, which is favored by users for its advantages such as large crushing ratio and stable operation of equipment. The process of bluestone crushing production line: the stone is exploded from the mountain, the stone less than 1020mm is fed into the vibrating feeder through the dump truck, the vibrating feeder sends the stone to the jaw crusher evenly, the jaw crusher crushes the stone in the first stage, the stone from the jaw crusher is around 150mm-300mm, then the material is sent to the impact crusher or cone crusher by vibrating feeder for the second stage crushing. The material is graded and screened by the circular vibrating screen, and the material larger than the finished product is returned to the impact crusher or cone crusher for re-crushing, the finished product is transported to the finished product area by belt conveyor. Yusheng Machinery's limestone crusher is designed by combining the current international advanced technology, with advanced technology, smooth operation, high crushing ratio, uniform material size, simple structure, reliable performance, easy maintenance and economic operation. Wear-resistant parts are always made of excellent manganese steel castings, and also combined with advanced technology and customer feedback, based on years of crusher industry, the company leads the development and production of large and medium-sized limestone crusher, continuous innovation and improvement, in the large and medium-sized crusher market field has been at an advanced level. Bluestone aggregates processed by the crusher sand making machine are widely used in many fields such as highways, high-speed railways, rural roads, construction sand, etc. Bluestone is an ideal material for the construction industry.
