At the end of 2020, in 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 version), which divided stone materials into two categories: one is waste processing enterprises, which need 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, and it requires that the categories and contents of environmental impact assessment be greatly simplified to reduce the burden on enterprises. In short, due to 202 1, the stone processing plant is not a highly polluting project, and environmental protection approval is not required! Greatly reduced the burden on enterprises.

The sand and gravel produced by stone processing plants meet the use standards of sand and are essential structural materials in the construction industry. In recent years, the demand for sand and gravel is increasing, which is in short supply and has a very broad prospect. The price of sand and gravel produced by stone processing plants has also been high, with considerable profits. Many investors have turned their attention to 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 equipments are jaw crusher, cone crusher, impact crusher, hammer crusher, impact crusher and so on. And the production requirements are 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, sand crushing.

Impact crusher, also known as impact sand maker, has a very small particle size, less than 60mm, so it is often used with other crushing equipment with large particle size. The machine is highly intelligent, stable and reliable, and can produce 0-5 mm sand and gravel. The grading of finished materials is reasonable and meets the standards for sand use. It is also often used in combination with a sand washer. The finished product is cleaned by a sand washer to remove impurities, which is cleaner and sells better.
