A washing section is part of the processing line, with its own feed, product and water requirements. Alborz’s plant equipment includes spiral sand washers and thickeners; the arrangement is reviewed for each project.
01
Identify what needs to be removed
Explain whether the feed carries clay, silt or excess fines, and which sand fraction you want to keep. A grading analysis and representative material sample provide a more useful starting point than a machine size alone.
- Describe the feed before washing and the required finished sand.
- State the intended use and any product acceptance criteria.
02
Connect washing to separation
Washing, classification and moisture removal serve different duties. Review the full material route so that the selected equipment retains the useful sand fraction and provides a product suitable for the next stage.
- Identify the product, fines and water streams in the proposed layout.
- Discuss the condition needed for conveying and stockpiling.
03
Plan the water circuit
A thickener separates settling solids from water. Water supply, return-water requirements and the handling of settled material all need space and a defined route in the plant.
- Record the available water supply and site drainage conditions.
- Include settling, water storage and maintenance access in the layout.
Common questions
Does every aggregate line need washing?
No. Washing is considered when the feed and finished-product requirements justify it. The type of contamination and the required grading should be reviewed first.
Can process water be reused?
Water recovery can be considered within the plant design. The usable quantity and quality depend on the material and the selected separation and water-treatment arrangement; a recovery percentage must be confirmed for the project.
Can a sand washer alone guarantee a dry product?
Washing and moisture removal are separate duties. Agree the required product condition and the downstream handling method before selecting the washing section.
