洗沙機普遍應用于建筑工地、砂石廠、水電站混凝土大壩工地等多種行業，它具有洗凈度高，構造合理，處置量大，功耗小，洗砂過程中砂子流失少，特別是洗砂機傳動局部均與水、砂隔離，毛病率大大降低，關于洗沙機來說，固然應用普遍，但也不是一切的物料都合適，對物料清洗還是有一定請求的，若是強行清潔不適宜的物料的話，不只得不到原有的洗選效果，還會對洗沙機本身構成危害，所以再遇到以下物料時要先做一下加工處置再進行清洗工作


    1、有堿活性的骨料應停止充分的實驗證明，適宜的進行清洗，不適宜的應盡量避免運用，否則會對洗沙機有所損傷。

    2、對質量指標不契合的物料要經過恰當加工處置后。達標后亦可進行清洗工作，不達標的盡量避免運用。

    3、關于風化巖體，當風化不影響單顆石料的物理力學性能和化學穩定性，稱心質量需求時，亦可選用。

    4、中選用節理裂隙發育，特別是隱節理發育的巖體作骨料，應停止有關實驗，證明骨料能否稱心質量和塊度需求。

    5、選用砂巖等巖性改動大的巖石作質料時，有必要停止有關實驗證明。

    6、破碎后骨料針片狀含量超越規范規則的石料不宜選用，有必要運用時，應采用改良骨料粒形的工藝方法。

Sand washing machine is widely used in various industries such as construction site, gravel plant, concrete dam site of hydropower station, etc. it has the advantages of high cleaning degree, reasonable structure, large disposal volume, small power consumption, and less sand loss in the process of sand washing. Especially, the transmission parts of sand washing machine are isolated from water and sand, which greatly reduces the gross disease rate. As for sand washing machine, although it is widely used, it is not all materials All of them are suitable. There is a certain request for material cleaning. If the unsuitable materials are forcibly cleaned, the original cleaning effect will not be achieved, and the sand washing machine itself will be harmed. Therefore, when the following materials are encountered, they should be processed and disposed before cleaning
1. The aggregate with alkali activity shall be fully tested and proved to be suitable for cleaning, and the unsuitable aggregate shall be avoided as far as possible, otherwise it will damage the sand washing machine.

2. Materials with inconsistent quality indicators shall be processed properly. Cleaning can also be carried out after reaching the standard, and the unqualified ones shall be avoided as far as possible.
3. As for the weathered rock mass, it can also be selected when the weathering does not affect the physical and mechanical properties and chemical stability of single stone and satisfies the quality requirements.
4. When selecting the rock mass with joint and fissure development, especially the hidden joint as the aggregate, relevant experiments should be stopped to prove whether the aggregate can satisfy the quality and block demand.
5. It is necessary to stop relevant experiments when sandstone and other rocks with large lithology change are selected as materials.
6. After crushing, it is not suitable to select the stone whose needle and flake content exceeds the standard rules. If it is necessary to use it, the process method of improving the aggregate shape shall be adopted.
