Description

technical field

Background technique

As a new type of environmentally friendly green building material, dry-mixed mortar has the advantages of stable quality, high efficiency, energy saving and environmental protection, and easy mechanized construction. However, since the raw material sand used in dry-mixed mortar requires a moisture content of less than 0.5%, most of the raw material sand cannot be directly used in production, and must be dried to make its moisture content meet the production requirements. During the drying process, the temperature of the sand will also rise accordingly, and the discharge temperature often reaches above 80°C. After the hoist lifts the hot sand into the sand storage tank, the hot and humid air brought in along with the hot sand meets the relatively cold wall of the cylinder, and the water evaporates and condenses to form condensation. These condensations make the fine sand easily adhere to the wall of the cylinder, gradually forming thicker and thicker agglomerates, affecting the discharge of the sand and making it difficult to clean; in addition, the sand entering the sand storage tank cannot Start production immediately, otherwise the quality of dry-mixed mortar will not be guaranteed, which will affect the production efficiency of dry-mixed mortar.
