After the raw materials and fuels enter the factory, they are sampled and analyzed by the laboratory, and they are homogenized according to the quality and stored in the raw material storage shed. The clay, coal, and pyrite powder are dried by the dryer to the process index value, and are lifted to the corresponding material storage tank by the elevator.
After two stages of crushing, limestone, fluorite and gypsum are sent to their respective storage tanks by the hoist. According to the quality of limestone, clay, anthracite, fluorite and pyrite powder, the laboratory calculates the process formula, and carries out the ingredients of the whole black raw material through the raw material micro-machine batching system. The raw material mill grinds and samples every hour. The percentage of calcium oxide, ferric oxide and fineness of raw raw materials was measured and adjusted in time to make the data meet the requirements of the process formula. The black raw material that has been ground is put into the raw material storage tank through the bucket elevator, and the laboratory homogenizes the raw material through the multi-library matching and the mechanical dumping method according to the quality of the raw material, and the two are lifted by the elevator. Raw material homogenization library, the raw material is matched by two homogenization banks, and the material is raised to the ball-making silo, and the ratio of material and water is adopted by the pre-watering ball control device arranged on the vertical kiln surface. The ball is placed into a ball of raw material.
The ball formed by the vertical kiln is placed in different positions in the kiln for calcination. The clinker is sent to the clinker crusher through the discharge pipe and the squaring machine for crushing. The laboratory samples every hour. Chemical and physical analysis of clinker at a time. According to the quality of clinker, the hoist is placed in the corresponding clinker warehouse. At the same time, according to the production and operation requirements and the building materials market, the laboratory will clinker, gypsum and slag through the clinker microcomputer batching system for cement proportioning. Grinding of ordinary Portland cement No. 425 and No. 525 was carried out separately and sampled once every hour for analysis and inspection. The milled cement is fed into the three cement storage tanks by the bucket elevator. The laboratory homogenizes the cement according to the quality of the ground grinding cement through the multi-library matching and mechanical dumping method.
After the elevator is fed into two cement homogenization warehouses, and then matched by two cement homogenization warehouses, the PC is packaged by the microcomputer-controlled packaging machine, and the packaged cement is stored in the finished product warehouse, and after passing the test and sampling test. Issue a cement factory notice.
