Limestone crushing sand production line
Limestone property
Limestone is mainly composed of calcium carbonate (CaCO3), Mohs hardness 3, is a soft rock, is a common ore, with chemical resistance, acid resistance, not easy to corrode, belongs to a soft material, after processing, can be used to produce glass, coating materials, desiccant and building materials required raw materials.
Limestone crushing production line flow
Limestone aggregate production line is divided into coarse crushing, medium and fine crushing, screening three stages.
- The first stage: coarse crushing: The limestone material blown down from the mountain is uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing.
- The second stage: medium fine crushing: The coarse crushed material is sifted by vibrating screen and transported by belt conveyor to the impact crusher for fine crushing.
- The third stage: screening: The medium and fine crushed stone is transported to the vibrating screen through the belt conveyor to separate different specifications of stones, the stones that meet the customer’s particle size requirements are transported to the finished material pile through the belt conveyor, and the stones larger than the upper screen size are returned to the impact crusher through the belt conveyor to break again, forming a closed cycle.
Limestone sand production line flow
The limestone sand making process is divided into four stages: coarse crushing, medium and fine crushing, sand making and screening.
- The first stage: coarse crushing: The limestone material blown down from the mountain is uniformly fed by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing.
- The second stage: medium breaking: The coarse crushed material is sifted by vibrating screen and transported by belt conveyor to the impact crusher for crushing. The crushed stone is transported to the vibrating screen through the belt conveyor to separate different specifications of stones, and the stones that meet the customer’s particle size requirements are transported to the finished material pile through the belt conveyor, and the stones larger than the upper screen size are returned to the impact crusher through the belt conveyor to break again, forming a closed cycle.
- The third stage: sand making: The stone whose material after crushing is larger than the size of the two-layer screen is transported to the sand making machine for fine crushing and shaping through the belt machine.
- The fourth stage: screening: After fine crushing and shaping, the material is sifted into coarse sand, medium sand, fine sand and other specifications by circular vibrating screen.
Note: For the sand with strict powder content requirements, a sand washing machine can be added behind the fine sand, and the sewage discharged by the sand washing machine can be recovered by the fine sand recovery device, which can reduce environmental pollution on the one hand and increase the sand production on the other hand.
Technical description:
1. This process is designed according to the parameters provided by the customer. This flowchart is for reference only.
2. The actual construction should be adjusted according to the terrain.
3. The mud content of the material can not exceed 10%, and the mud content will have an important impact on the output, equipment and process.
4. Yuyuan Machinery can provide process plan and technical support according to the actual requirements of customers, and can also design non-standard supporting parts according to the actual installation conditions of customers.
