1.Selection basis of dry mix mortar plant
Due to the dry mix mortar has the advertisements that versatile, mixing and painting quickly, good water retaining, good workability, good cohesiveness, save money and so on, so it Is a very good investment prospects of the project. But how to choose suitable dry mix mortar plant according to local enterprises’ conditions is a problem for many investors. Dry mix mortar also known as mortar powder. It refers to product by the special manufacture, and it is a kind of mixed material which through drying, screening, mixing. It can be transported by special tanker to the site for mixing with water, it also can be transported to the construction site by bags. The dry mix mortar production progress mainly include raw sand screening, raw sand handle, mortar mixing and so on. After mastering the dry mix mortar production system, the mortar can be produced according to their demand, and choose a suitable dry mix mortar plant. 2.Equipment selection principle
The dry mix mortar  plant production progress is complex, due to it include many mixing equipment.Choosing the appropriate mortar configuration needs consider the mortar type and capacity, raw sand type, drying heat source equipment, mixing host, silo configuration, packaging machine six Aspect consideration.
(1)Types and Capabilities of Production of Mortar According to the situation of the local construction market, its share of the market, and the future market trend, the production and types of dry mix mortar should be calculated annually. Firstly, production capacity There are two classification methods between the dry mix mortar industry: (1) The hourly output, that is, how many tons of dry mix mortar can be produced per hour. Currently, there are mainly 20t/h, 40t/h, 60t/ on the market. h, 80t / h These models. (2) Annual production, that is, how many tons of dry mix mortar can be produced per year. Currently, there are mainly 100,000 tons/year, 200,000 tons/year, 300,000 tons/year, and 400,000 tons/year on the market (calculated according to annual work). 300 days, two shifts a day, eight hours per shift, 4800 hours per year) These models.Secondly, types of mortar produced: Ordinary mortar: masonry, plastering, ground, ordinary waterproofing, etc.; special mortar: self-leveling, special waterproof, tile bonding, insulation bonding, external insulation plastering and other mortar. Thirdly, selection principle The general mortar or special mortar should be produced according to the required mortar market demand and the mortar to be produced, and the type of mortar line to be constructed should be determined according to the production mortar. If it is necessary to produce both ordinary mortar and special mortar, it is not recommended to use large stations (that is, stations with higher production capacity) that can produce both ordinary mortar and special mortar. Because the production process of those large stations is too long, and the types of additives used in the production of special mortars are too many, the amount of use is small, and the price is relatively expensive, the additives are easily lost in transportation and metering, so that the production cost is invisibly improved, and the produced mortar is in the process. There is no price advantage in the market competition. If both mortars are produced, it is recommended to build a large production line to produce ordinary mortar and another small equipment to produce special mortar.
