Hi Marlin. Thank you for your question.

Sand washing machine can’t satisfy all kinds of stones. If you wash stones by unsuitable sand washing machine, not only the washing effect is not good, but also it will damage the sand washing machine.

Firstly, alkalinity aggregate should be avoided to use sand washing equipment as far as possible.

Secondly, Weathered rock can’t use sand washing machine. But when weathering won’t influence physical property and chemical properties of stones, we can also choose sand washing machine.

Thirdly, when you want to process the rock whose lithology changes easily, there should be an experiment proving sand washing machine can be used.

Fourthly, when needle-like materials take a large proportion, you can’t use sand washing machine.

In a word, sand washing equipment has certain requirements for the material, hardness and granularity of raw materials. So selecting suitable materials for sand washing machine is very important.
