Due to the introduction of environmental protection policies this year, coupled with the global epidemic and heavy rains in various regions in China, the price of sand and gravel has risen. On the other hand, traditional, backward, and illegal sand and gravel plants have been closed in various places, causing the output of sand and gravel to fall far short of demand, resulting in a shortage of sand and gravel in many areas. In addition, with the promulgation of the national “new infrastructure” policy, sand and gravel are indispensable as the most basic raw material. The original inconspicuous sand and gravel industry has been pushed to the cusp of the storm. Under such a severe situation, what should the gravel yard do survive? For sand and gravel plants, environmental protection is mainly limited to dust and noise. Generally, closed production can achieve a large degree of green environmental protection.
1. The installation of multi-effect dust removal equipment is indispensable. At the same time, the production line adopts a partially enclosed design and adopts a dust cover to collect the generated dust, which can reduce dust pollution to a large extent;
2. The closed board room design can significantly reduce noise pollution and realize one of the important conditions for environmental protection of the sand and gravel production line.
If you want to build a green, environmentally friendly, reasonable and efficient sand and gravel production line, on the one hand, you must purchase environmentally friendly production equipment, and on the other hand, you must make a green and environmentally friendly design and configuration of the sand and gravel production line. For the design of environmentally friendly sand and gravel production line, there are the following requirements:
1. Be targeted.
There is so much environmentally friendly equipment, but not all of them are optional. The raw materials are different, and the equipment involved in the process used is also very different. The same scheme has long been in the past. Today's market is to combine your raw materials and on-site tailor-made design schemes, adapt to material conditions and local conditions.
2. The layout should be clear.
Modular design can prevent the conveyor belt from pulling and pulling randomly, and the equipment is randomly placed. The coarse crushing, fine crushing, and screening modules look clear at a glance. The materials are transported from the feeder to the stack in an orderly manner, thus realizing the whole the production line operates efficiently and produces efficiently.
3. Stable sand and gravel gradation control and high quality of finished materials.
High-yield is relatively speaking, and the quality of sand and gravel has certain data indicators. The quality of sand and gravel directly affects the quality of concrete and buildings. High-quality sand and gravel are indispensable. At present, Luoyang Dahua Heavy Industry produces many types of impact the crusher has high sand making efficiency. The finished products are all cubic particles with very good grain shape. The advanced crushing cavity design has low dust pollution and low noise. It is one of the ideal equipment for environmental protection sand factories.
4. The control must be scientific.
At present, many sand and gravel production lines on the market have PLC intelligent control, and some equipment can realize video monitoring and other links, which greatly reduces labor costs, and the control will be more scientific, and the production of gravel plants will be more professional.
