Structure of an Aggregate Wash Plant:
1. Collection of the material in a chute. A feeder controls infeed material.
2. Separation and washing of the different grain size fractions in a Mogensen sizer with irrigation.
3. Gravel and other fractions go directly under the Mogensen sizer, between walls or with conveyor belts to stock pile.
4. Washing and dewatering of the sand pulp and water which goes through the small mesh of the screener. The best way of carrying out this stage of washing is by means of a hydrocyclone with a dewaterer. The washed and drained sand is obtained during this stage, as well as the dirty water resulting from the process.
5. Sand drained and clean goes to stock pile via conveyor, usually gyratory type.
6. Clarifying of the dirty water, containing clays and filler, in a settler or clarifier with the help of a flock solution. There are two aims on this stage: recover the most quantity of water to the process; and concentrate the generated slurry as good as possible to reduce its volume in sludge storage or to optimize the size of the press filters.


The work principle:

1. Water's pulp feed and dirty sand to the tank.
2. Pump stage from the principle tank to cyclone.
3. Pulp cyclone stage (sand separation and clay or filler).
4. Clay and water entry from cyclone to the secondary tank to the automatic regulation of principle tank level by a buoy’s system.
5. Cleaned sand wringer from cyclone.
6. Clay or filler and water exit from secondary tank to decanter.
7. Sand exit already washed by a chute to the accumulation.
