Dry mortar is also called dry mixed mortar. It is a mixture of dry powdery aggregate (sand), cementitious material, and chemical additives. It is controlled by computer and mechanized. The product can be shipped to the site in bulk. The proportion of water is added to stir, and the new dry powder mortar can be used directly. Liming Heavy Industry Technology introduced a series of sand making machines for dry powder mortar production process. Following the low-carbon economy and environmental protection policy, Liming Heavy Industry Technology recommends that the dry mortar production option be based on the use of sand in the mine to replace the natural sand as the aggregate of the dry mortar by using the sand-making mechanism sand; cement is used as the cementitious material for mortar strength; Instead of fly ash, the fine powder in the waste rock of the mine is used instead of the fly ash to change the thickening and paving properties of the dry mortar. The use of reasonable thickening additives to adjust the high-quality mortar and construction performance has changed fundamentally. The original mortar production process achieves the goal of no drying, comprehensive utilization of resources, 100% bulk operation, no pollution, zero emissions, more energy saving, and more environmental protection.
At present, dry mortar mainly includes: masonry mortar, dry concrete and special mortar (color mortar). Masonry mortar is mainly used for the masonry of walls and structural parts, such as masonry clay bricks, concrete blocks, and stone materials. It can also be used for interior and exterior wall plastering projects. The special mortars are mainly plastering mortar, adhesive mortar, facing mortar, self-leveling mortar, repair mortar, etc., and can be used for plastering of floors and walls, plastering of ceramic tiles, decorative materials, insulation materials, etc. Repair of waterproof layer, concrete structure, etc. According to different conditions and uses, there are nearly 50 special mortars currently being developed. Liming Heavy Industry Science and Technology Sand Maker has the function of fine crushing and coarse grinding. The product has a cube, high packing density, minimal iron pollution, simple and reasonable structure of the sand making machine, and low operating cost. According to the site, materials and investment, Dawn Heavy Technology introduced three This series of sand making machine: PCL series through impact crusher (sand making machine), SX series of high efficiency centrifugal impact crusher, VSI series of high efficiency vertical axis impact crusher (new type of sand making machine, gravel shaping).
Liming Heavy Industry Co., Ltd. has built a series of dry powder mortar production lines for cement and new materials. The finished products are used in concrete projects and large building materials, and have obtained certain production and use experience.
Low carbon economy dawn sand making machine dry powder mortar production new model
At the national legal and policy level, Trinity Development Bulk Cement, ready-mixed concrete, and ready-mixed mortar were identified as specific measures for the comprehensive utilization of resource cycles and energy conservation and emission reduction. The use of dry mortar can achieve mechanized operations, reduce labor costs, increase production efficiency, and avoid In the case of on-site preparation due to raw materials, it is prone to quality problems caused by mixing errors or doping. The use of dry mortar has a large radius of use and a wide range of supply; it facilitates the use of bulk cement and changes the status of bagged cement entering the construction site. From a commercial point of view, dry mortar is a value-added product of cement. However, in order to truly meet the low-carbon economy model, the dry powder mortar production model must be further explored.
