The misalignment of measurement is usually caused by the instability, drift and linear out-of-tolerance of the scales in use.+
The concrete mixing plant has high productivity due to its high degree of mechanization and automation, and it can guarantee the quality of concrete and save cement. It is often used in large and medium scale water conservancy, electric power and bridge projects with large amount of concrete works, long construction period and concentrated construction sites. This paper shares common faults and troubleshooting methods of 8 systems in concrete mixing plant.
During the operation of the concrete mixing plant, the stirring system is a very important part. During the operation, it drives the rotation of the whole tank and the stirring device through the stirring rotating device. During this process, the feeding device and the unloading device will realize the coordination and transportation of concrete and ensure the real-time and efficient mixing.
For some large concrete mixing plants, their overall control is based on the PLC control system. In their operation process, especially in some harsh environments, various electrical failures are easily caused by external factors, thus affecting the operation of the concrete mixing plant.
During the operation of concrete mixing plant,
Have seen a major role in our daily concrete batching plant is quantitative, accurate delivery a variety of materials, so long as the grain, bulk materials such as: sand, coal, food raw materials, slag, ceramic, etc. can delivery (but single every kind of material weight distribution preferably not less than 50Kg), so batching plant is also widely used: aerated concrete bricks, light panels and other building materials industries, coal mine gravel ingredients wall construction, chemicals configuration.
far. France began to research concrete pump as early as 1907. The French Feliz Haier had designed and manufactured concrete delivery pump in 1927, and achieved the first successful application. In China, concrete delivery pump had been imported from abroad in 1950s. For example, 252 type concrete pump from Soviet Union had been used in the construction of Wuhan Yangtze River Bridge. Because of the deficient conditions at the time, continuous failures of the machine did not cause the attention of construction unit. From the 1960s to early 1980s, many manufacturers produced all kinds of concrete pumps of various displacement and operating methods through imitation, self-development and combining foreign technology. Some of them even passed the national identification, but no one had been widely used.
Cement quality is directly related to construction quality and its duration, so the control of cement quality is a crucial link for concrete mixing plant. However, today’s cement industry is in a mess, and the unqualified quality is common. Clinker in cement is far less than the standards. “Small cement” can not be called as cement, and it is just abrasive powder. Regulation on cement is in heavy deficiency. Just depending on inspection strength, setting time and the stability is not enough.
Fully automatic concrete mixing plant well reduces labor amount in construction project, and more humanized designs are added in terms of using this kind of concrete mixing plant.
After completing the installment and the maintenance test, then separately gives various storage bins feeding, opens the discharge switch of feeding mouth between cement silo and the screw conveyer. Later, carries on the debugging.
Usually with a front end loader. Some people will build a tall ramp to fill their concrete plant directly with the front-end loader and other will use a feed system to feed the concrete plant.
