How to Treat Damp Soil in Cold and Rain‑Prone Regions? Application of Hengrui Roller Screens

In cold and rainy regions such as Northern Europe, Canada and the United Kingdom, frequent rainfall and low temperatures pose challenges to soil treatment. In landscaping, slope stabilization and mine ecological restoration projects, soil with high moisture content tends to stick and clump. Mixed impurities like stones and tree roots further complicate subsequent construction work.

Rainfall raises soil moisture content, causing soil particles to adhere to one another and form large soil clods. Conventional screening equipment often suffers from material adhesion, sieve aperture blockage and poor impurity separation when processing such materials. Therefore, selecting suitable screening equipment for wet soil is a key step in material pre‑processing for greening construction.

The Hengrui roller screen moves and screens materials via the rotation of multiple rollers. As soil passes through gaps between the rollers, materials meeting size requirements fall through, while large‑sized impurities such as stones and tree roots get separated. This screening structure suits a wide range of soil‑treatment scenarios and provides pre‑processed soil materials for landscaping and slope‑restoration projects. Actual screening performance depends on soil moisture content and material properties.

In overseas greening projects, wet-soil screening equipment is applied to lawn construction, road slope greening, mine ecological restoration and land consolidation. Screened qualified soil materials lay a solid foundation for subsequent vegetation rehabilitation and greening construction. Processed soil can also be used for hydroseeding operations. A hydroseeder mixes soil, grass seeds, water, fibers and other additives into slurry, which is then sprayed onto target slopes via spray guns. When roller screens work in tandem with hydroseeders, they connect soil pre‑treatment and slope greening processes, delivering a more complete greening‑equipment solution for international clients.

Hengrui Machinery manufactures roller screens and hydroseeding equipment for projects including landscaping, slope stabilization and mine ecological restoration.
