Tailings are waste residues discharged from mining enterprises after mineral processing. They are similar to construction waste. They are not useless. They are just misplaced resources. If they are just piled up in a chaotic manner, they will not only occupy land resources. In the long run, the harmful substances in them will seriously pollute the atmosphere and soil layers, causing harm to people's health. However, if the waste stone tailings are processed and made into high-quality sand and gravel aggregates, they can be reused in engineering projects such as engineering construction and road construction, which are both green and environmentally friendly. Benefits can be obtained.What equipment is used for sand making from tailings in the mine?What is the specific sand-making process?
What equipment is used for tailings sand making in mineral processing plants?
Under normal circumstances, mine tailings need to be treated with impurity removal before use, and then crushed and sand-making processing. Then it will inevitably use crushers and sand-making machines. If customers have strict requirements for finished products, they can also use sand washing machines in combination.Detailed information about the tailings sand making equipment of the mineral processing plant is introduced as follows：
The cone crusher is responsible for processing the coarsely crushed tailings into stones below 40mm. It adopts laminated crushing cavity type and fixed-axis structure design. The hydraulic motor adjusts the discharge port to adjust the operation and the crushing force is large. The touch screen automatic control system ensures the safe operation of the equipment, the touch screen operation interface displays the real-time working status, and all components can be disassembled and assembled from the upper part and the side, and the replacement is quick and convenient, which is loved by users.
The sand making machine is used for the re-fine crushing sand making operation after the cone is broken. The machine adopts a four-port impeller design and improves the impact angle of the crushing chamber. The throughput is greatly increased and the output is greater. The alternating use of the two working modes of stone beating stone and stone beating iron has a higher sand output rate. After its treatment, most of the finished mechanism sand is square and the particle size is more reasonable.In addition, it also has advanced safety protection devices, has iron-crossing properties, can effectively filter metal parts, prevent accidental damage to the sand making machine, and improve safety and reliability.
Tailings sand making process
The tailings sand making process is evenly sent from the vibrating feeder to the jaw crusher for coarse crushing. The coarse broken material is fed from the belt conveyor to the cone crusher for further crushing. After crushing, it is placed in the sand making machine for fine crushing. The finely crushed material is transported to the vibrating screen for screening, and the material that meets the particle size requirements of the finished product is sent to the sand washing machine for cleaning, and the output from the finished product conveyor belt after cleaning is the finished product.
Materials that do not meet the particle size requirements of the finished product are returned from the vibrating screen to the sand making machine for reprocessing, forming a closed circuit multiple cycles.The particle size of the finished product can be combined and graded according to the needs of users.If the dry production process is selected, it can be equipped with a coarse and fine powder separator and dust removal equipment.
