Transformation and upgrading of sand and gravel aggregate industry

Sand and gravel aggregate is an indispensable and irreplaceable basic material for construction, highway, railroad, bridge and water conservancy and other infrastructures with the largest dosage. With the rapid development of national infrastructure facilities and urbanization, the demand for sand and gravel for construction is in a period of rapid growth.

Along with the development of construction and infrastructure construction technology, the progress of sand and gravel aggregate production equipment technology is also in constant development, transformation and upgrading, elimination of backwardness, energy saving and emission reduction significantly accelerate the pace. At the same time, the development of sand and gravel aggregate is also due to the reduction of natural sand and gravel and the ban on mining and gradually to the process of mechanism sand and gravel. In the production of sand and gravel aggregate, its core technology is "crushing and screening", and its production process can be summarized as "fine crushing and screening".

At present, the sand and gravel aggregate industry is in a period of great development, for the industry and enterprises is a serious challenge, but also a good opportunity. The challenge is that the backward equipment, high energy consumption, small scale, environmental protection does not meet the standards, the rough operation of the enterprise will be eliminated. The opportunity is that enterprises with advanced equipment, environmental protection standards, low energy consumption, high production efficiency and good product quality can get greater development.

Sand and gravel aggregate is the largest amount of materials used in real estate, infrastructure construction, urbanization, rail transit, highways, railroads and other infrastructure construction, and the amount of sand and gravel aggregate in the next few years will show a steady growth trend. We believe that the upgrading of the technical level of the sand and gravel aggregate industry and the development process of industrialization will be very fast, and it will eventually develop into a modern industry integrating quarry mining, processing, storage and transportation with a high degree of integration, automation, scaling, green environmental protection, energy conservation, emission reduction, and recycling and reuse of waste materials.
