Manufacturer sale new generation gypsum mortar mixer machinery
Main introductions of gyspsummortar mixer machinery:
Gypsum mortar mixer machine is dry mixing machinery equipment for producing new energy-saving and environmentally friendly gypsum mortar materials. It is a complete production line solution professionally designed according to the raw material characteristics of gypsum mortar. The complete solutions includes multi-function system of raw material storage , automatic batching, conveying , mixing, packaging and automatic bag stacking, etc.
What is new type energy-saving and environmentally friendly gypsum mortar materials?
Plastering gypsum mortar is a newer, more environmentally friendly, and more economical product promoted in China instead of cement mortar. It not only has the strength of cement, but is also healthier, environmentally friendly, as well as durable, strong adhesion, not easy to chalk, no cracking, no hollowing, no powder drop, etc., easy to use and cost saving. In aspect of unit price, plastering gypsum mortar is more expensive than cement mortar, but plastering gypsum mortar has many advantages. Taken together, the cost of plastering gypsum mortar per square meter is lower than cement mortar.
Advantages of gypsum mortar:
When the outer humidity is higher than the relative humidity of the plastering gypsum mortar, the outer vapor pressure is higher than gypsum mortar saturated vapor pressure, the gypsum mortar will adsorb outer moisture, therefore, gypsum mortar can delay the humidity rise; when the outer humidity is lower than the corresponding humidity of the plastering gypsum, the outer vapor pressure is lower than gypsum mortar saturated vapor pressure, which promotes the evaporation of internal water molecules, so it can play a role in regulating and controlling humidity.
Plastering gypsum has the same life span as the building. It can be crushed together with gypsum blocks after being discarded. After low-temperature calcination, it has gelling properties and can be reused.
The shrinkage rate of traditional cement plaster mortar is generally 7-9%, and the expansion rate of gypsum is one thousandth, which determines that the shrinkage and hollow cracking of cement plaster mortar is inevitable during the hydration process, can only be alleviated by additives and curing, but it is impossible to completely solve it. The gypsum is slightly swelling. Under normal circumstances, it is impossible to produce hollow cracking during the hydration process. Moreover, the hydration process of gypsum is very fast, basically hydrating finish in 24 hours, so the volume stability is very good.
Using plaster plaster instead of traditional plaster cement mortar in the same construction area can reduce the consumption by half.
The thermal conductivity of gypsum mortar is 0.17W/MK, but the thermal conductivity of traditional cement mortar is 0.93W/MK, so the thermal conductivity of gypsum mortar is only 20% of traditional cement mortar, which has a certain thermal insulation effect. , Can reduce the energy consumption of the building.
The bulk density of gypsum mortar is 750-950kg/m³; only half of the traditional cement mortar 1800-2000kg/m³. For example, if a building (two units with 20 layer) is replaced by gypsum mortar instead of traditional cement mortar, the whole building will reduce the load by 550 tons.
The molecular weight of dihydrate gypsum is 172, and the molecular weight of water is 18. When a house of 100 square meters encounters a fire, when the temperature reaches 110°C or higher, the dihydrate gypsum will quickly release crystal water and turn into hemihydrate gypsum and then further turn it into no water. Hydrogypsum can release 560kg of water. The water can absorb a lot of heat during the evaporation process, which can effectively prevent the rapid rise of the room temperature and improve the chance of escape.
The molecular weight of dihydrate gypsum is 172, and the molecular weight of water is 18. If a house of 100 square meters encounters a fire, when the temperature reaches 110°C or higher, the dihydrate gypsum will quickly release crystal water and change to hemihydrate gypsum and then further turn it into no water, hydrogypsum can release 560kg water. The water can absorb a lot of heat during the evaporation process which can effectively prevent the rapid rise of the room temperature and improve the chance of escape.
After the gypsum is harmlessly treated, it does not contain soluble pollutants. The inorganic cementing materials and additives used are all environmentally friendly products. The light plastering gypsum does not release harmful substances such as formaldehyde, which is environmentally friendly and safe.
Since the bulk density of gypsum mortar is onlyhalf of traditional cement mortar, workers only need to pay half of their physical strength for the same area. Therefore, the labor intensity of workers will be greatly reduced and the construction efficiency will be improved. In addition, no maintenance is required after plastering, the hydration and setting time is short and the next process can be constructed after 24 hours.
During the setting process of gypsum mortar, there are tiny voids inside, so it can attenuate sound pressure, prevent sound energy projection, can convert sound energy into heat energy, so it has good sound insulation performance. Due to the condensed porous structure, it can effectively absorb impact energy, so it will not crack and fall off when subjected to impact.

Main raw materials of gypsum mortar:
Gypsum mortar mainly includes gypsum powder, expanded perlite, cement, sand and chemical additives.
Due to the density, flowability, sizes of gypsum, expanded perlite, cement and sand are quite different, even the production line is similar to tranditional cement mortar mixer machine, however, these materials features need us choose special machinery equipment in producing of gypsum mortar. Now we introduce the configuration details of gypsum mortar mixer machine and solution for producing dry mix gypsum mortar.
The structure of gypsum mortar mixer:
1. The main mixer machine of the dry mix gypsum mortar production line adopts a double-shaft non gravity paddle mixer. The gypsum mortar mixer machine has the characteristics of fast mixing speed, no dead corners and no buildups in the mixing drum, and pneumatic door discharge which is fast and easy in discharging well mixed gypsum mortar.
2. Raw material sand cement silo and automatic batching system. This gypsum mortar production line has an automatic raw material proportioning system. Only a small amount of raw materials need to be added to the additive material batching silo at one time. The later material proportioning only needs to choose the setted gypsum mortar formula on control system, thereby greatly improving production efficiency.
3. The end product silo with secondary mixing which can solve the problems of material stratification during the discharge process after the mixing is completed, ensure the uniformity of the finished product after packaging. The finished products are subpackaged through the valve port quantitative packaging system. The packing machine adopts computer metering which has stable performance, simple operation and is equipped with a dust removal port to reduce the harm of dust to the human body and realize environmentally friendly production.
