Limestone is a type of white stone that contains calcium , used in building and in making cement, Most limestone is composed of skeletal fragments of marine organisms such as coral or foraminifera.Limestone makes up about 10% of the total volume of all sedimentary rocks.
VSI crusher machine can be used in Pebble, rock (the limestone, granite, basalt, aluminum, andesite, etc.), ore tailings, slags, artificial sand production. Can be used in Building aggregate, highway, asphalt concrete and cement aggregate production.
Raw material falls down into feed hopper, and then the material enters impeller through central entrance hole. It is accelerated in high-speed impeller, and then it is thrown out at the speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet.
Raw material falls down into feed hopper, and then through ring, it is divided into two parts by material-dividing plate. One enters into impeller through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impeller at the speed of 60-75m/s, is hit coming down from outside of material-dividing plate. In this way, material is crushed.
