The sand and gravel separator has a compact structure, simple operation, manual and automatic control process, and full display of faults, which is convenient for transportation, installation and maintenance. The effective working area is spacious, and one or two cars can be provided for unloading and cleaning at the same time.
Features of each component of sand and stone separator:
1. Separation system: The spiral advancing direction of the screen tube is designed at an inclination angle with the horizontal, so that the material can be fully inverted during the limited screening process, and it can be cleaned and separated by the jet water flow. The reasonable arrangement of the height of the overflow groove on the upper part of the sedimentation tank of the sand separator can fully separate the sand particles and the mud. The auger is installed asymmetrically with the inner wall of the shell. Fully dehydrated during the process. The sand and stones are completely separated at one time. Separation capacity may be 0-30 t / h.
2. Water supply and drainage system: The cleaning process of the whole system adopts cyclic cleaning, so the sewage is basically zero discharged, and the water resource reuse rate is high.
3. Electric control system: It adopts Japanese original PLC control, which has more powerful functions and more convenient maintenance. The control process is fully automatic, full fault display and alarm. Improve the stability and reliability of the whole machine, all control modules are installed in the switch box that is not affected by weather, and the automatic operation is easy to control and maintain.
4. Easy to operate: Pour the mixer truck to the set parking space, and perform water washing and roll washing, then pour the waste slurry water directly into the feed hopper, and the feed hopper flows into the separator for cleaning and separation. The separated gravel is sent to the sand outlet and the stone outlet respectively. The overflowed water flows through the drainage ditch to the sedimentation tank, and then is pumped back by the water pump after passing through the three-stage sedimentation. The water is recycled and the mixer is washed for about five minutes. In addition, models with different specifications can be manufactured according to demand.
