What Are the Material Requirements for China Silica Sand Washing Machines?

The China silica sand washing machine is widely applied across various sectors, including construction sites, sand and gravel plants, and concrete dam projects at hydropower stations. It delivers high cleanliness levels, a robust structural design, substantial processing capacity, and low energy consumption. While versatile, sand washing machines have specific requirements regarding material compatibility. Processing unsuitable materials can compromise equipment integrity. Therefore, if you encounter the following types of materials, pre-processing and disposal are required before cleaning.

1. Alkali-reactive aggregates. When handling alkali-reactive aggregates, alkaline content must be treated first, followed by washing with the sand washer.

2. Materials that do not meet quality indicators must undergo proper processing. Cleaning should only proceed once the materials reach the required standards.

3. Weathered rock mass. If weathering does not compromise the physical and mechanical properties or chemical stability of individual stones, these materials can be cleaned directly using the sand washer.

4. When selecting sandstone and other rocks with significant lithological variations as materials, the stability of their physical and chemical composition must be verified before cleaning them with a .

5. If the content of crushed aggregate exceeds the specified limit, it cannot be cleaned directly using a . The shape of the aggregate must be improved prior to cleaning.
