Generally, the general dry mix mortar production line requires that the sand sieve be divided into four particle size grades of 0-0.6 mm, 0.6-1.18 mm, 1.18-2.36 mm, and 2.36-4.75 mm. For special mortars, the classification requirements for sand are finer. The influence of sand grade on the quality of dry mix mortar is very large.

Jan 24, 2020 Another method to separate components of a mixture is based on melting point. The melting point of salt is 1474F (801C), while that of sand is 3110F (1710C). Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801C, yet below 1710C.
