As China's sand industry enters a period of transformation and upgrading, multiple real estate can be released, and there is an imbalance between supply and demand of sand and frequent price fluctuations. A large number of enterprises that do not meet the environmental requirements of sand and stone have been ordered to rectify, and river sand mining has also been banned to a certain extent. Environmental protection storm swept the entire sand and gravel industry.

Environmental protection mine construction is urgent, good environment needs us to build together. However, green mine construction is not a simple plant greening, the coverage rate of vegetation is important, but the key to the main generation of dust and pollution is the production process. Therefore, optimizing the production process and building an environmentally friendly sand production line is the core of low-carbon environmental protection.

In the sand making process, the stone crushing process is a major cause of dust, especially in the crushing process of large materials, dust is serious. The impact environmental protection sand making production line in Jinhai, Henan Province, is a closed treatment of the entire production line, and dust collectors are set up at the main places where dust is generated. In this way, the entire production line is almost in a completely closed mode, there is little dust pollution, and the generation of dust can be avoided directly from the source.

Henan Tomings Machinery dust collector has two kinds of air box pulse bag dust collector electrostatic dust collector. The air box pulse bag dust collector has the advantages of separate chamber blowback and jet pulse blowback. It overcomes the disadvantages of insufficient kinetic energy strength and simultaneous pulse dust cleaning and filtration, enhances the adaptability of use and improves the dust collection efficiency. The power supply of electrostatic precipitator is composed of control box, booster transformer and rectifier. The output voltage of the power supply also has a great influence on the dust removal efficiency.
