Why are wet production processes less and less used?

The main reason is:

1) A large amount of water is consumed, and 1 t of sand and stone material needs 2 ~ 3.5m³ of water

2) The product has high sand water content and must be dehydrated, and dry again for dry mixing;

3) The product sand fineness modulus is relatively coarse, and the sand output is low;

4) A large amount of mud powder sewage is produced, which pollutes the environment, and stone powder is not easy to recycle;

5) There are many types of infrastructure investment and equipment, and the production cost of machine-made sand is high;

6) Normal production is not possible in arid and rainy areas or during the freezing season.
