Desen Screening plant: A "Grading Expert" for Soil Remediation

In soil remediation projects, "precise classification" is key to improving efficiency. When contaminated soil is mixed with rocks, plastic fragments, and unevenly coarse and fine soil particles, without prior classification, subsequent washing and solidification processes can be like a flood, consuming large amounts of reagents and failing to guarantee effective remediation. The Desen screening plant addresses this pain point.
At the remediation site of a chemical contaminated site, the screening plant's operational process clearly demonstrates its "classification intelligence." During operation, contaminated soil is delivered to the feed port by a forklift and first passes through the upper bar screen. This screen has adjustable mesh spacing. Due to the site's high gravel content, operators set the mesh spacing to 15 cm to quickly intercept large impurities and prevent them from entering subsequent systems and causing blockages.
Next, the lower multi-layer grading screen activates, precisely classifying the remaining soil into three grades based on thresholds of 5 mm and 20 mm. On-site testing data shows that the primary pollutants at the site are concentrated in fine soil particles smaller than 5 mm. Therefore, after screening, only this fine soil needs to enter the deep processing line. Medium-particle soil of 5-20 mm can be used as backfill after simple purification, and coarse particles larger than 20 mm are directly used for roadbed paving.
This "on-demand grading" model has reduced the project's subsequent processing volume by nearly 70%, chemical usage by 55%, and shortened the remediation cycle by one-third. For the remediation team, the screening plant is more than just a piece of equipment; it acts as an experienced "grading expert." By scientifically categorizing soil layers, each remediation step is precisely targeted, truly achieving the "efficiency and precision" of environmental protection projects.
