Classification of aggregates and how to build an environmentally friendly gravel production line

The equipment configuration of sand and gravel production line generally adopts two-stage crushing of coarse crushing and fine crushing, and some stones also need three-stage crushing or shaping, and then screening. Coarse crushing usually adopts gyratory crusher, jaw crusher and other equipment, medium crushing adopts impact crusher or cone crusher, and fine crushing and shaping commonly adopts impact crusher (sand making machine).

For sand and gravel plants, environmental protection is mainly limited to three aspects: dust, noise and sewage. The installation of multi-effect dust removal equipment is a must, while the production line adopts local closed design and dust collection hood to collect the dust generated, which can reduce the dust pollution to a large extent; the design of closed cubicle can obviously reduce the noise pollution, which is one of the important conditions to realize the environmental protection of sand and gravel production line. So, what are the classifications of aggregates? How to configure an environmentally friendly sand and gravel production line?

Coarse aggregate: also known as stone, is the aggregate with a particle size greater than 4.75 mm, mainly cobblestone and artificial gravel, cobblestone is a nearly round or oval rock formed naturally by natural weathering or water transport and other natural formations, gravel is mainly made by mechanical crushing and screening, according to its use is not the same, the raw material can be limestone, lapis lazuli, river cobblestone, granite, basalt and other types of rocks

Fine Aggregate: also known as sand, is the aggregate with a particle size of less than 4.75 mm, mainly natural sand and artificial sand, natural sand refers to river sand, lake sand, mountain sand and desalinated sea sand, etc.; Artificial sand is crushed by the sand making machine, the rock is crushed into the natural sand like the particles of the same raw materials and crushed stone, you can choose a variety of rocks according to its use.

Sand and gravel aggregate production line is a line operation equipment integrating feeding, crushing, screening, product lifting, conveying and dust removal. By reasonably allocating the crushing ratio and optimizing the details of the sand and gravel aggregate production line, the efficiency of the sand and gravel production line can be improved and the quality of the mechanism sand and gravel can be enhanced.

The configuration of the sand production line in the quarry needs to be comprehensively calculated and selected according to the environment, materials, investment and other factors.
