I believe everyone knows that all walks of life are not too optimistic now, especially the real estate and machinery industries, which are in a depression. Now the concrete market has been saturated to a mature state, and the concrete industry has also Without the huge profits of the past, in order to survive and develop, commercial concrete mixing stations can no longer follow the old routine. In addition to strengthening their own management, they must explore concrete materials and concrete mixing techniques. In the traditional mixing process, concrete is mixed with cement, sand and gravel dry-mixed and then water is added. The admixtures are put into the mixing pot at one time for mixing. After a period of time, the materials are discharged to form new mixed concrete. This advantage is realized by the equipment and process. It's very simple. The disadvantage is that a layer of free water film will be formed on the surface of freshly mixed concrete sand and gravel, which will increase the water-cement ratio in the interface area, so that the role of the cement slurry is far from being fully exerted.
How to bring out nearly 30% of the effectiveness of cement, reduce the amount of concrete cement, reduce the cost of concrete, and reduce the waste of resources, is a commercial concrete mixing station manufacturer The common development goals of commercial concrete mixing stations.
At present, the low environmental protection of my country's concrete mixing station equipment needs to be improved and improved from three aspects: dust, noise and pollution. In terms of dust, it is necessary to control the powder transportation path. For example, using imported dust collectors on cement silos, installing dust collectors in the main building, changing screw conveyor feeding to air trough feeding, and closing the entire station can reduce dust. To the minimum level; noise can be reduced to the minimum by improving the performance of the host, closing the station, and using materials such as soundproof panels; in terms of pollution, it must be carried out through various ways, such as building wastewater sedimentation tanks and secondary circulation filtering devices and bone Secondary use of materials. In addition, all powdery materials are carried out in a closed state from loading, batching, metering, feeding to mixing and discharging.
The dust exhaust pipes of the mixer cover, cement metering bin, and fly ash metering bin are all connected to the dust collector, and the aggregate filling port is equipped with a dust-blocking plate to reduce Dust emissions. The fully enclosed mixing main building and belt conveyor structure greatly reduce dust and noise pollution to the environment. The use of negative pressure dust removal and special fiber filter cloth allows the dust generated during feeding to completely enter the dust collector without spreading to the surroundings. The collected dust can be easily recycled and reused, effectively protecting the environment. </p
