Dry-mixed mortar production principle

The use of advanced, reliable automation equipment, dry mortar, dry mortar production of high quality products, basic conditions. Dry-mixed mortar production process is not complicated, mainly by raw material preparation and delivery, weighing and batching, mixing, and dry mortar products packaging, palletizing and other production technology components. Quartz sand dry mix raw materials normally subject to special drying equipment, making them less than 0.2% moisture content, and then by vibration screening of 4 to 5 different size, with a bucket elevator conveyor to the appropriate silo in the back. Cement, lime powder and other cementitious materials commonly used filling equipment, pneumatic conveying raw materials into the silo. Some materials may also need to by crushing, grinding treatment, in order to meet size requirements. Chemical additives (dispersible polymer powders, cellulose ethers, etc.) can be manually added to a small warehouse of raw materials, the formula automatically by the control system required ingredients, you can also manually weighing, directly into mixer (now the domestic good point dry mortar mixer manufacturers generally use gravity, coulter mixer) use.
Currently the advanced dry mortar production plant are the top-down process layout (tower dry mortar production line, depending on dry-mixed mortar production factory site and other factors, the role of a small footprint, but the dry mix mortar manufacturer’s plant has a high degree requirements), all raw materials raised to the top of the silo, to rely on the quality of their raw materials in the natural flow from the hopper, the weighing, batching, mixing, packaging and other processes became the final product. All production is in the modern computer control system operation for completion. As long as the operator to determine the type and quantity of the product, the rest all operate by the control automatically, without human intervention. All equipment used in confined production systems, not only on-site clean, no dust pollution, to ensure the health of workers, but also has produced a large amount of ingredients, high precision, the use of flexible features.
Because the production line and raw material silos erected vertically in the mixing device (mixer) above, so most of the production of 40,000 tons to 250,000 tons / year of the modern dry-mix mortar plant.
Appropriate quality control of raw materials during the after transport to the receiving system through the top of the silos in the plant. Basic material flow by gravity or other delivery systems (such as disc feeder, dosing screw, pneumatic, etc.) sent to the accuracy of the hopper scale weighing system. All processes through automatic electronic control system to control a particular dry mortar ingredients required to mix all the raw materials into the device (mixer) in.
Mixing equipment they use a special mixer (mixer) for different dry mix products (from coarse particles to the dry mix mortar). Mixing equipment with different capacities and structures, you can achieve rapid and homogeneous mixing. Throughout the mixing process, dry-mix mortar temperature should not exceed 50 ℃, in order to avoid sensitive thermoplastic additives and quality degradation. Modern and efficient equipment for mixing, in a mixed 3 minutes to 10 minutes, homogeneous dry mix can be discharged into the finished product storage warehouse in the middle. Conducting quality control, dry-mixed mortar is discharged into the transport silo or bagging equipment or transferred to palletizing equipment, ready to transport to construction sites.
In the production of dry mortar, the use of raw materials, particularly bulk inorganic material, must comply with national standards. If the quartz sand and other aggregates can not meet the quality requirements, then dry-mixed mortar production plant must be equipped with grinding, washing, drying and screening equipment. All filler no more than 0.3% residual moisture, and after drying, the sand temperature before use should not exceed 60 ℃. Different filler particle size of the sieve curve should be stable without large fluctuations.
Raw material silo design, capacity, quantity, and the mixing and packaging equipment design depends on the raw materials and dry mortar production plant in a variety of dry mix of quantity, variety and size. For gypsum-based products, usually require a separate production line, cement-based products in order to avoid contact with or mixed with plaster affect product quality.
Production of dry mortar with quartz sand dryer critical equipment (general domestic use drum dryer), screening machines, electronic weighing batching systems, mixers, packaging machines and computer control systems. Other pneumatic equipment material handling equipment, bucket elevator, automatic palletizing machines, forklifts, trucks and other auxiliary equipment, may need to use. Some simple laboratory analytical instruments for testing and controlling the quality of dry mix products.
Dry-mixed with cement, mortar products, finished products commonly used in bulk, can also be bagged. In the Southeast Asian market is the most common paper bag lined with plastic film packaging dry mix products, the general weight 20 kg bag 40 kg. There are big bags, the general weight 1000 kg per bag. For the large amount of products available 2 kg to 5 kg of small packages. Dry mortar products, packaging, depends not only on market needs, but also the ability to consider and form of packaging equipment.jaw crusher Impact Crusher
