Self mixing concrete mixer. Weighing is a very important link in the concrete mixing plant. In order to ensure the production of high-quality concrete, it is necessary to weigh the concrete raw materials. Therefore, the weighing system in the concrete mixing plant needs the following requirements:
Self mixing concrete mixer. It is necessary to expand the temperature and humidity range. The working environment of the concrete mixing plant is different from that of the general commercial scale. The working environment of the general commercial scale is generally relatively stable, while the stress environment of the load sensor in the mobile concrete mixing plant is very complex, the operating conditions are relatively worse and have greater randomness. The concrete mixing plant is usually installed in the open air. The sensor is often exposed to the sun and rain, and the temperature is in a great change state.
Self mixing concrete mixer. Higher corrosion resistance requirements. The working environment of concrete mixing plant is very bad. There is not only a large floating space for temperature and humidity, but also a certain corrosivity. A large amount of cement, pulverized coal ash and an appropriate amount of admixture are required in the production of concrete. These powders will produce dust in the process of transportation and weighing. Some of this dust will adhere to the surface of the load cell. Under the combined action of dust and water vapor, the sensor will be seriously corroded.
Self mixing concrete mixer. Some special design is required. The concrete mixing plant is generally installed on the construction site, and the working quality of the staff will also affect the use of the weighing system. Temporary workers are widely used on the construction site, and a considerable number of them have low educational level and lack necessary skills. In the maintenance and cleaning of equipment, it is likely that the sensor will be sputtered by high-pressure water and overload will be caused by misoperation. The sensor needs some special design to operate reliably for a long time under such environmental conditions.
