The main component of limestone is calcium carbonate (CaCO3), which is widely used as a building material and is also an important raw material for many industries. In our country, it is a resource with a wide range of uses and is widely distributed. Limestone can be used as coating material and brick binder; it can be directly processed into stone and fired into quicklime; mixed with clay, etc., and calcined at high temperature to make cement; mixed with quartz sand, soda ash, etc. to make glass through high temperature melting ; Ironmaking uses limestone as a flux to remove gangue; steelmaking uses quicklime as a slag-making material to remove harmful impurities such as sulfur and phosphorus; calcium carbide is made by reacting quicklime and coke in an electric furnace; limestone is processed into purer powder Calcium carbonate is used as a filler for rubber, plastic, paper, toothpaste, cosmetics, etc.
Limestone crushing process
Limestone process configuration: limestone-vibrating feeder-jaw crusher-impact crusher-vibrating screen-conveyor-finished product
The limestone is evenly fed by the vibrating feeder to the jaw crusher for primary crushing. The materials after the initial crushing and the fine materials screened by the vibrating feeder are transported to the impact crusher by the belt conveyor, and then the impact crusher is crushed. Machine crushing (medium and fine crushing), and then use the circular vibrating screen to screen the limestone after the impact crushing: larger particles of limestone are returned to the impact crusher and crushed again, and the qualified materials will be classified according to requirements and conveyed by the conveyor belt To different storage piles for storage or directly by truck to the construction site.
