With the development of construction industry, people all over the world pay more and more attention to environmental protection. Dry mix mortar production line comes into people’s sight. Owing to the rigid matching ratio and the different functional requirements of mortar, added corresponding chemical additives, greatly improve the quality of mortar. The application of dry mix mortar avoids the mass defects of manual preparation on site, ensures the quality of construction, meanwhile reduces the municipal refuse and improves the environmental pollution, improves the degree of civilized construction. It is a kind of green and environment-friendly new building material with broad market prospect. Dry mix mortar refers to the uniform mixture that the sand through drying screening added little cementing material ( cement, gypsum) and micro high-tech additives, according to the scientific formula processing. The finished mortar has the characteristics of shrinkage resistance, crack resistance, heat preservation and moisture resistance according to different USES. Products can be packed or bulk shipped to the site, according to the specified proportion of water mixing can be used directly. The production process of dry mix mortar production line is as follows:
(1). Sand pretreatment includes quarries, crushing, drying, (grinding), screening and storage. If there is river sand, only need to dry and screen, can directly purchase the finished sand into the warehouse if there has conditions.
(2). The cementing material, filler and additive shall be sent to the corresponding storage.
(3). Ingredient measurement according to formula.
(4). Put all kinds of raw materials into the mixer for mixing.
(5). The finished mortar is sent to the finished warehouse for packaging or bulk packing.
(6).Production is sent to construction site. Bulk dry mix mortar must be transported by bulk silo or special bulk transport vehicle to prevent segregation and affect the quality of construction.
(7).Put the dry mixed mortar into the mortar mixer and add water in proportions. Use the special mortar pump to transport the mixed mortar to the construction site or directly carry out the on-site shotcrete construction.
（8）Main composition is sand, 70%, its proportional occupancy is 70%and moisture content range is big, the moisture content of sand and used to dry mortar can only be controlled between 0.2% and 0.5%, otherwise will seriously affect the quality of dry mortar products store, so when buy the raw sand must take the attention to the sand moisture content determination, drying, screening and conveying. To ensure that the finished mortar does not contain water is the key to guarantee the quality of dry mix mortar, in order to accurately control the speed of the dry sand machine drum, it is necessary to measure the water content in the sand. The drying speed can also be set after laboratory measurement. The drying of raw sand is completed by a dryer. At the present there are two main methods are used, namely, vibrating fluidized bed and machine drum type.
（9）Dry mix mortar production line is used for the centralized mixing of ordinary mortar and special mortar, also known as dry mix mortar consumption plant. Can be divided into two types according to the mixing mode: single-mixed dry mix mortar equipment and double-mixed dry mix mortar equipment; According to the construction mode: simple dry mix mortar equipment, serial dry mix mortar equipment and tower dry mix mortar equipment. The control mode is manual, semi-automatic and fully automatic.
