How to Screen Soils with Different Moisture Contents? Analysis of the Application of Hengrui's Two Types of Soil Screening Equipment

During the soil screening process, moisture content is one of the important factors affecting screening quality. For the same soil, when the moisture content is low, it is relatively loose, and soil clods are easy to break and separate. As the moisture content increases, the soil gradually becomes sticky and forms clumps, and the difficulty of screening also changes accordingly. Therefore, in actual construction, it is necessary to select appropriate screening equipment based on the moisture state of the soil. Hengrui Machinery has launched a rotary drum soil crushing and screening machine and a wet soil screening machine to address different soil material states, providing equipment solutions for processing soils with various moisture contents.

When the soil moisture content is low, the soil material is usually relatively loose, but during excavation, transportation, or long-term stockpiling, larger soil clods may also form. Before such soil material enters subsequent spray seeding, it typically needs to be crushed and screened to bring it to a more suitable state for use. Hengrui rotary drum soil crushing and screening machine means that after the soil material enters the equipment, it moves forward with the continuous rotation of the drum. During operation, larger soil clods are crushed, and screening is completed through the screen mesh. Therefore, for situations with low moisture content, relatively loose soil material, and the presence of many large clods, the rotary drum soil crushing and screening machine can combine crushing and screening into a single processing flow.

As the soil moisture content increases, the degree of adhesion between soil particles also changes. The originally relatively loose soil material may gradually form clumps, especially during rainy season construction or after rainfall when the soil material has high moisture content, and the soil tends to stick together. At this time, traditional screening methods designed for dry soil may no longer be suitable. For this type of soil material, the equipment needs to handle the characteristics of wet soil, rather than simply relying on crushing large clods to complete screening. Hengrui wet soil screening machine is designed for screening wet soil, frozen soil, and other soil materials in different states.

For situations with low moisture content and the presence of many large clods in the soil material, the rotary drum soil crushing and screening machine can be used to process the soil material by combining crushing and screening. For situations with high moisture content and soil material that tends to form sticky clumps, the wet soil screening machine can be considered to screen wet soil and other special-state soil materials. The difference between the two types of equipment is not just their structural differences; more importantly, they are designed for different soil material states. From dry, loose soil material to wet soil with high moisture content, the actual soil conditions at the construction site directly affect the screening method. Configuring equipment according to the actual soil state can make the soil material processing more aligned with construction needs.
