At the end of 2020, official website, the Ministry of Environment, issued a new edition of the Catalogue for Classified Management of Environmental Impact Assessment of Construction Projects (202 1 year edition), which divided stone materials into two categories: one is waste processing enterprises, which require environmental assessment; Second, sheet processing enterprises only need to fill in the registration form. At the same time, the Catalogue more accurately reflects that the stone industry is not a highly polluting industry, which requires that the categories and contents of environmental impact assessment be greatly simplified to reduce the burden on enterprises. In short, since 20021year, the stone processing plant is not a highly polluting project, so there is no need for environmental approval! Greatly reduced the burden on enterprises.
The sand and gravel produced by stone processing plants meet the standards of sand use and are essential structural materials in the construction industry. In recent years, the demand for sand and gravel has been increasing continuously, which is in short supply and has a very broad prospect. The price of sand and gravel produced by stone processing plants has also remained high and the profits are considerable. Many investors have set their eyes on the sand and gravel industry.
What equipment does the stone processing plant need? According to different raw materials and production requirements, the required equipment is also different. At present, the common equipment includes jaw crusher, cone crusher, impact crusher, hammer crusher, impact crusher, etc., and the production requirements are also different.
1, jaw crusher+cone crusher, processing hard materials;
2. Jaw crusher+impact crusher to treat soft materials;
3, hammer crusher, gravel molding at one time;
4, fine jaw crusher+impact crusher, crushing sand.
Impact crusher, also known as impact sand maker, has a very small feed particle size of less than 60mm, so it is often used with other crushing equipment with large feed particle size. The machine is highly intelligent, stable and reliable in operation, and can produce 0-5mm sand and gravel. The finished material has a reasonable gradation and meets the standard of sand use. It is also often used in combination with a sand washer. The finished material is cleaned by the sand washer to remove impurities, which is cleaner and sells better.
