In the dry mix mortar production line, Compared with mechanical meters, electronic meters have the following advantages: 1. no mechanical adjustment, no mechanical wear, easy maintenance than mechanical meters; 2. automatic display of empty bag weight before loading; 3. electronic meter can be used on the keyboard. The whole process of packaging in dry mix mortar production line can be carried out or the automatic packaging process can be established. The whole process of the packaging process can also be controlled by a computer. The production control points of bagged dry mix mortar are the accuracy of measurement and the separation of materials. Some dry mix mortar production lines are improperly arranged. For example, if the gap between the intermediate tank and the mixer is too large, the material may be segregated; some packaging machines may be unreasonably designed to cause segregation. The test method is: sampling from the dry mix mortar of different packaging bags for strength homogeneity test. The allowable range of measurement error of bagged mortar is: the error per bag is within 98%, and the total mass of 20 bags is not less than the weight of the mark. The packaging bag is required to be sealed. The bagged dry mix mortar should not be piled on the cement floor. There should be a silo board or a plastic cloth isolation floor. The stacking height of the large-packaged mortar should not exceed 8 skins. The warehouse should be well ventilated, and the storage period of the bag in the mortar should not exceed 3 months. In the dry mix mortar production line, There are two kinds of storage technology for bulk dry mix mortar: one is “mobile storage tank system”, which is a technical way for bulk dry mix mortar to be used by foreign companies. The specific procedure of this system is: use the back tanker to carry the tank filled with dry mix sand slurry to the construction site, and then use the hydraulic system of the back tanker to stand up the storage tank and put it on the construction site, and then use the back tanker to empty the empty space. The tank is back to the mortar factory for loading. The other is “pressure tanker transport and on-site fixed tank system”. This system is a technical way of bulk mixing of dry mix mortar proposed by Nanjing Tianyin Special Purpose Vehicle Co., Ltd. in combination with the actual situation in China. The specific procedure of the system is: transporting the dry mix mortar to the construction site by using the special dry mix mortar for transporting the mortar, and then using the air compressor carried on the special transport tanker to drive the dry mix mortar to the site for anti-separation. In dry mix mortar production line, the mortar storage tank, the water is automatically added through the continuous agitator connected to the lower part of the storage tank, and then the material is stirred at the site.
For large quantities of products in the dry mix mortar production line, such as masonry, plastering, self-leveling mortar, etc., silos are increasingly used. It is transported to the construction site in bulk form, and mechanized construction is carried out in conjunction with the conveyor system and construction machine. Unused materials can also be returned to the factory to truly achieve a lossless cycle. The volume of common silos varies according to materials and uses, and has different specifications such as 1.0m3, 1.2m3, 5.0m3, 12m3, 18m3, 20m3, and 22m3. Compared with the developed countries, the domestic bulk dry mix mortar logistics system is characterized by the use of dry mix mortar transport vehicles instead of the back tank trucks, which solves the problem of easy separation of materials during transportation and transportation, and meets the needs of large-scale construction in China, reducing The flow of the storage tank improves the work efficiency and greatly reduces the logistics cost. The cost of dry mix mortar is lower than that of bagged dry mix mortar by 19.44 yuan/t, accounting for 10% of the total cost. In 2005, it has used 3 million tons of dry mix mortar.
