Product Introduction
Limestone, also known as calcite, is a common nonmetallic ore whose main component is calcium carbonate. China is rich in limestone mineral resources, accounting for 64% of the world’s total reserves. It is a mineral resource with natural advantages. Its hardness is 3 in Mohs, and the density is 2.60~2.75 g/cm3. The limestone can be directly processed into stone materials and fired into raw lime, and can produce casting sand for machinery castings. The granularity of cast sand is 28~75 mesh. This kind of sand has better performance than quartz sand with easy collapsibility. It is easy to fall and clean. And it can improve the quality of casting surface and increase its luminosity. At the same time, lime and limestone can be used for building materials in a large scale and they are also raw materials for many industries. In view of the widespread application of limestone, TYM has researched into limestone sand making equipment and developed a set of associated equipment for limestone sand.
Technical Process
Limestone raw material is sent into jaw crusher uniformly and continuously by vibrating feeder for crushing, then the crushed stone is transported to transit bin for composting by conveyor belt. The crushed material is sent to the conveyor by feeder at the bottom of transit bin, then it is sent into impact crusher for fine crushing. The stone that meets the requirement is screened and cleaned in the following process. Large stone will return to impact crusher for second crushing. After crushing, the material is sent into circular vibrating screen by conveyor for screening, which can be divided into different kinds of finished stones. Machine sand enter roller washing machine to clean and remove dust and high quality machine-made sand is produced.
