What Are The Equipment Of Chrome Ore Washing Plant?
1. The raw materials are unloaded from the excavator to the raw material bucket and then evenly fed to the drum washer by the vibrating feeder. The vibrating feeder has a screen with a gap of 70mm to prevent large stones from being contained in the raw materials. Large rocks larger than 70mm can be removed from the screen feeder.
2. The trommel scrubber is used to wash the raw materials and screen out waste materials larger than 2mm. The raw materials are mostly soil and clay, which must be cleaned by the drum washer first (2 layers of PU screens) with mesh sizes of 2mm and 20mm. The 20mm PU screen protects the 2mm mesh.
3. After the efficient washing and screening by the drum washer, the -2mm material is swiftly pumped to the roughing spiral chute, a total of 18 sets. The roughing selected materials are then efficiently pumped to the fine spiral chute for further sorting to improve the recovery rate. There are 9 fine spirals, with a total of 27 sets of spiral chutes, ensuring the process is highly productive.
4. All chrome concentrates from the roughing and fine spiral go into the magnetic separator to reduce some magnetite iron, thereby improving the chromium/iron ratio.
5. The chrome concentrate from the magnetic separator, a highly effective tool, is pumped to the shaking table, and a total of 30 sets of shaking tables are used. Every 15 sets of shaking tables correspond to a distribution tank, and a pump is used to send the chrome concentrate to the distribution tank and then distributed to each set of shaking tables. The shaking table – the final fine separator, is a testament to the quality of our process, effectively further improving the chromium grade in the concentrate to meet customer requirements. The middlings from all shaking tables are returned to the selection spiral chute for re-separation to improve the recovery rate. Then, the tailings from the shaking table are sent to the sedimentation tank.
6. The chrome concentrate from all shaking tables is sent to the spiral dewaterer to remove most of the moisture. The underflow of the spiral dewaterer enters the dewatering screen for further dewatering, so the dewatered concentrate can be transported to the finished product pile by a belt conveyor. The overflow of the spiral dewaterer and the under-screen slurry are returned to the hydrocyclone by the pump. The cyclone overflow enters the sedimentation tank, and the overflow enters the dewatering screen, which is the whole process of the dewatering system.
