With the rapid economic development, the environment we depend on for survival is getting worse and worse. These high-frequency words (haze, PM2.5, carbon emissions, etc.) have repeatedly touched our sensitive nerves. Environmental problems have seriously affected the sustainable development of the country, energy saving and environmental protection is imminent. Henan Ouwei Industry, as the leading manufacturer of mining machinery and equipment, fully implement the national environmental protection policy, mainly in the following aspects.

1. The use of energy-saving and environmentally friendly raw materials Ouwei industry fully implement the national concept of energy conservation and environmental protection, most of the raw materials required for the equipment is the state advocates the priority use of energy-saving and environmental protection materials. With the gradual input of energy-saving and environmentally friendly materials, our professional technical team continues to research and optimize the structure of the equipment, reduce the production costs of equipment and user investment, and ultimately maximize economic benefits.

2. Adopting energy-saving and environmental protection technology

1) In terms of crushing technology, we combine our actual production experience with advanced design concepts, and perfectly combine reasonable crushing frequency and eccentricity according to the characteristics of the equipment itself, so as to reduce energy consumption, improve product quality and increase users' benefits in the production process.

2) For sand making technology, according to the famous stone beating stone crushing principle and technology, we have developed a leading level of high efficiency stone crusher - sand making machine, the 'stone beating stone' crushing cavity makes the crushing efficiency higher, the unit capacity high and the investment income considerable.

3) For rotary kiln technology, the rotary kiln equipment produced by OWI Industry has advanced structure and stable performance of the vertical preheater can effectively improve the preheating effect and increase the decomposition rate of materials. In addition, at both ends of the rotary kiln, there is a combined sheet seal design, which makes the air leakage coefficient small, less heat radiation loss and high waste heat utilization, which can save energy consumption.

3. Our energy-saving and environment-friendly equipment Henan Ouwei Industrial's equipment is produced in strict accordance with national environmental protection standards. For example. Cone crusher saves more than 20% energy than conventional cone crusher; hammer crusher can reduce the comprehensive operating cost by 40%; jaw crusher with high output and low cost is very popular; ball mill saves more than 45% energy than conventional ball mill, while avoiding the disadvantages of slow start and high noise; grinding equipment has a qualified rate of up to 99%, and the unique sealing device makes the dust not leak out during the production process, which ensures the workshop is clean and tidy, etc.
