Qingdao Huangang Heavy Industry Technology Co., Ltd. based on the process characteristics of the current dry mixed mortar production line, combined with domestic and foreign technology and experience accumulation, launched a new automatic energy-saving dry mixed mortar complete set of equipment. The equipment can be combined with dry sand making system or wet sand drying system to produce high quality and high standard dry powder mortar and special mortar. The main building adopts the tower structure, the powder bin is installed on the top of the main building, and the admixture system adopts an independent platform for metering and pumping. The aggregate passes from top to bottom through the metering layer, the mixing layer, the finished product warehouse, the control room, the bulk machine, the packaging machine.

The production line with an annual output of 400,000 tons of ready-mixed mortar can produce the required dry powder mortar in real time after the mortar formulation requirements are confirmed by computer metering precision | and stirred by the mixing machine. Most special mortars can also be manufactured according to the formula. The whole process adopts automatic operation mode.

Reliable dust removal system
Dust removal system is an essential process configuration in the mortar production line. According to the different process requirements and characteristics of the dry powder mortar production configuration process, Huanang Heavy Industry has all kinds of dust collectors in the dust prone points to ensure that all powder can be carried out in a closed environment, reduce environmental pollution, and dust emission meets the national standards. Improved working conditions and improved the recycling rate of raw materials.

High performance hybrid system
Mixing system is a key part of dry mixed mortar production, but also the "heart" of the factory, Huanang Heavy dry mortar production pure configuration of international standard mixing mixer, mixing uniformity is suitable, mixing time is controllable, excellent repeatability/low maintenance rate can be configured with high-speed flying knife, according to the working condition to open the blade, to achieve mixing and dispersing fibers and pigments.

Precise | accurate measuring system
The precision and accuracy of the measurement | is very critical to the product. For particles and raw materials with poor fluidity, the measurement system with proprietary technology can achieve fast and accurate automatic measurement. The measurement system is mainly divided into two parts: raw material measurement and admixture measurement. Huangang Heavy Industry uses well-known metrological components to ensure the accuracy of our metrological systems.

Gas delivery system
After the powder is stored in the transfer bin, the powder is transported to the designated powder bin for storage through Roots fans and star feeding valves and ball valves. A special structure is adopted at the bifurcation of the pipeline to ensure that there is no mixing phenomenon when conveying different powders. Each powder storage bin is equipped with a cloth bag type pulse dust collector and explosion-proof safety valve, material height indication, to ensure the environment and safety.

Huangang Heavy dry powder mortar production line production principle and advantages:

The main control system issues production instructions according to the selected process formula, the system automatically extracts raw materials according to the ratio from the storage bin, and the raw materials enter the mixing bin and the single-axis mixer successively after counterweight, to achieve rapid mixing operation (3-5 minutes). After reaching the mixing accuracy requirements, the finished mortar is transported to the finished product warehouse and enters the automatic filling process. The newly designed automatic packaging machine carries out regular and quantitative filling operations according to the requirements, greatly improving the output efficiency. The packaged finished products are sent to the finished product area for stacking and waiting for delivery.

The mortar production line with an annual output of about 20,000 tons will generally use 3-6 raw material tanks, of which two large tanks are used for loading bulk cement and fly ash, and the remaining small tanks are used for loading light calcium, heavy calcium, sand, etc. Bulk cement and fly ash into the tank does not require lifting equipment, relying on the pump truck to drive. Bulk fly ash bin is generally a cylindrical support structure, the upper part of the dust removal equipment to prevent dust leakage, the lower part is equipped with an arch breaking device to prevent the powder from caking, so that the powder is discharged smoothly, and is equipped with a material level sensing equipment, you can know the use of materials in the bin at any time.

Light calcium, heavy calcium, sand, etc., need to use a bucket elevator to lift into the raw material tank, and the clever material distribution system supports a bucket elevator distribution operation, thereby avoiding resource waste. The measuring system, with the coordination of the measuring screw, introduces the raw materials in the bin into the measuring bin, and realizes the measurement of raw materials through the data feedback of the sensor. The measured material can be dropped directly into the mixer. The mixing bin is pneumatic big door type, which can quickly put the material to be mixed into the non-gravity mixer to realize continuous production of dry powder mortar. The finished product mixed in the mixer is quickly placed into the finished product bin for buffering and storage through the hydraulic discharge system. The finished product silo and the packaging machine enter the packaging machine for measurement and packaging through a soft connection. Users with large output can add belt conveyors in the rear process of the packaging machine to directly transport the finished product to the finished product area or truck.

Note: The above figures are based on double shifts of 16 hours per day, 300 days per year.
