The control of the level of the central feeding system and the characteristics of the weight loss metering feeder determine that the feeding mode of the mixing hopper is batch feeding.
Therefore, each batch feeding of the mixing hopper will cause large fluctuations in the material level. For the continuous and stable feeding of the system, it is necessary to implement reliable automatic control of the material level of the mixing hopper.
The central feeding is the way of weighing and measuring, and the material level is controlled in real time.
Mixing hopper set high material level, low material level, when the material reaches the high material level, the total amount of material to the mixing hopper decreases by 5%; Similarly, when the material reaches the low level, the total amount of material fed to the mixing hopper is increased by 5%. Keep the material level of the mixing hopper fluctuating in this interval.
In addition, it is necessary to set ultra-high and ultra-low material levels for alarm. Note that the weight-loss metering feeder should not frequently and greatly change its set parameters, because after the parameter is changed, the feeder will automatically correct to a stable state, which requires a process of about 10 ~ 40s.
The installation height of the central feeding equipment is reduced, and the maintenance is convenient. Most of the equipment such as the weight loss measuring feeder and mixing hopper are installed in a higher place (6 ~ 13m from the ground) in the foreign program, while the weight loss measuring feeder is only 2 ~ 3m from the ground in the self-designed program, and the mixing hopper is only 5m.
Therefore, the self-designed scheme is better and conducive to equipment maintenance. Central feed The reasonable scheme design not only meets the process requirements of the system, but also greatly reduces the engineering manufacturing cost and the operation cost of normal production.
In the grain processing industry, pneumatic conveying system is an important material conveying method, which is widely used in the process of grain storage, cleaning, drying, grinding and so on. Compared with traditional mechanical conveying methods, pneumatic conveying systems have the following advantages
Pneumatic conveying system plays a key role in cement production, which is mainly used in raw material conveying, pulverized coal conveying, clinker conveying and other links in cement production line. The following is the application of pneumatic conveying system in cement production
The Central feeding system is a modern feeding solution that provides efficient and accurate material supply for a variety of industrial and commercial sectors. The system is composed of centralized control unit, conveying equipment and distribution mechanism, which can realize automatic and intelligent material supply management. The advantages and applications of the central feeding system are described below.
As a modern material supply solution, the central feeding system not only offers advantages in terms of increased efficiency and accuracy, but also makes a positive contribution to the environment and sustainable development. The important role of central feeding systems in environmental protection and sustainable development is described below.
Founded in 1926, Garton is one of the largest and most advanced food enterprises in Hong Kong at that time. Garton's main production facilities are located in Hong Kong and mainland China, producing food products including bread, biscuits, cakes, confectionery, etc. Since the 1980s, Garton has been actively developing the Chinese market.
