Bulk material is a major form of material that exhibits different states depending on the physical and chemical properties of the material, including powder, granules, block, and liquid. Its processing also involves the main aspects of material preparation, transportation, storage and packaging. This article will briefly introduce the bulk material conveying engineering.
I. Bulk Material Handling
Bulk material processing involves the main links of preparation, transportation, storage and packaging. Each link has strong professionalism, and has its specific development rules and characteristics, especially material preparation. This aspect can be subdivided into A number of development directions, and China’s research and development in these areas in the world also have different positions.
2. Bulk Transporting
Modern bulk material transportation is one of the transportation methods for bulk shipments that we encounter every day, such as ore, coal, grain, sand, cement, and various industrial raw materials. There are many ways to use the bulk material conveying device. According to the conveying principle, it can be roughly divided into three categories: mechanical conveying mode, fluid pipe conveying mode and container conveying mode, as shown in the following figure:
Among them, the fluid pipeline transportation method is one of the modern transportation modes that are being applied and have a promising future with high efficiency, small land occupation, low cost and small pollution. The following figure shows the cargo fluid pipeline transportation system that is currently being developed and applied to various industries. It can be seen that its wide application range and many disciplines are sufficient to illustrate its broad application development prospects. Undoubtedly, pneumatic conveying plays an important role in fluid pipeline transportation systems.
- Application Scope
With the development of production and the increasingly automated production process, bulk material conveying technology has been rapidly developed and applied. In the process of continuous exploration and innovation, the conveying target is extended to cement, sand, chemical raw materials, fly ash, coal powder and other materials. The scope covers grain, building materials, ports, chemicals, metallurgy, electric power, foundry, food, medicine and other fields.
