1. Industry overview
Machine-made sand belongs to the sand and gravel aggregate industry. Sand and gravel aggregate is a general term for sand, pebbles, gravel, block stone, material stone and other materials in construction projects, and is a natural resource second only to water in the world. The material with the largest and most widely used material in engineering construction is concrete, and sand and gravel is the most important component of concrete raw materials, accounting for about 6 7 of the concrete mass, and is the skeleton of concrete; Nearly two-thirds of the world's sand and gravel aggregates are used in concrete.
2. Supply and demand in the industry
The annual output of sand and gravel aggregates in the world is about 40 billion tons, and China is the largest sand and gravel producer, accounting for about 50% of the global sand and gravel production, and the annual output value of the national sand and gravel aggregate industry is close to 2 trillion yuan. In 2021, China's sand and gravel output was 19.7 billion tons, and the output from 2013 to 2021 remained around 18 billion tons, and the output of sand and gravel aggregates continued to remain at a high level.
China is also a big consumer of sand and gravel aggregates, with about 15 billion tons of sand and gravel aggregates used for concrete every year, plus asphalt concrete, water treatment and other uses, a total of about 20 billion tons are consumed every year, accounting for about half of the world's total. Due to China's large population base, large economy and high economic growth rate, China Sand and Gravel Association** During 2020-2030, China's annual demand for sand and gravel aggregates will reach a high level of 25 billion tons and run smoothly.
3. The technical level and technical characteristics of the industry
(1) Beneficiation technology
The beneficiation technology of the industry mainly adopts magnetic separation, gravity separation and flotation. Magnetic separation method is a beneficiation method that realizes mineral separation in an inhomogeneous magnetic field according to the principle that different ores are subjected to different forces in the magnetic field of the magnetic separator due to the difference in magnetic properties.
Re-selection methodSorting is carried out according to the specific gravity of the mineral and its different sedimentation velocity in the medium.
FlotationIt is a process in which solid minerals are floated from the slurry through the action of chemicals according to the differences in physical and chemical properties of the mineral surface, and the separation of the target minerals from other minerals is realized. Due to the use of chemicals in the flotation method, it has a certain impact on the environment and human beings.
(2) Ore blending technology
Due to various natural factors, there are large differences in the quality of natural ores in different mining areas or different ore layers in the same mining area, which directly determines the large fluctuations in the indicators of products, and the downstream industry has higher requirements for the quality consistency of garnet sand products, so mastering the ore blending technology can improve the uniformity and stability of ore and concentrate quality, and improve the comprehensive economic benefits of mining and processing ore.
