per day, we recommend that the chalk be dried naturally. If the
customer's local temperature is too low, we offer drying
machine,temperature range :30-120ºC.Drying time around 12
hours. Work Principle of Chalk Making Machine:The main raw
material of chalk is calcium sulphate or calcium carbonate. After
adding water, it needs to be stirred constantly to avoid
solidification. After the mixed calcium sulphate is putted in the
chalk machine mold, the mixed calcium sulphate begins to solidify
in the mold, and the chalk has begun to be formed.After 10-15
minutes,the chalk in the mold can be taken out.How to make
