Energy conservation is to strengthen energy management and take measures that the environment and the society can withstand with feasible technology and rational economy to reduce losses and waste in energy production and consumption from every aspect and more effectively and rationally use the limit energy. The energy saving is a long-term development strategy for sustainable development in China, which is also China's basic national policy. With China's rapid economic growth and the improvement of people's living standards, the imbalance between supply and demand is obviously apparent and the environmental pollution is serious. Therefore, the energy saving task is arduous. The mining and metallurgical industry consumes large amount of energy every year.

The hydraulic cone crusher is a kind of cone crusher with international advanced level which has absorbed the advanced crushing technology of developed countries in Europe and the United States. There are four models of this machine including coarse crushing, medium crushing, fine crushing and ultra-fine crushing. The four models are designed for second-stage or three-stage crushing and all of them can be used in fixed or mobile sites. The new single-cylinder hydraulic crusher is widely used in metallurgy, construction, water, electricity, transportation, chemical industry and building materials industry. The entire control and the adjustment of the device produced by Henan Hongxing Mining Machinery lie in the bottom of the hydraulic cylinder of the crusher.

The crushing system of the single cylinder hydraulic cone crusher is mainly composed of the inner cone liner, outer cone liner, the bottom fuel tank and the gear. The part above the red line is mounted on the upper housing, while the part below the red line is mounted on the lower housing. The upper housing and the lower housing is connected by the bolts.

In recent years, the emergence of many major beneficiation technologies and energy-efficient crusher equipment provide the support of technology and equipment for the energy saving of ore beneficiation. For example, the grinding (semi-autogenous grinding and high pressure roller mill) replaces the crushing. The practice has proved that the ultra-fine crushing equipment can greatly reduce the granularity of the crushed product. More crushing less grinding can reduce the particle size of the crushed product, which is one of the most effective means of reducing energy consumption per unit production costs for the mining enterprises to improve production capacity. The green crushers produced by Henan Hongxing Mining Machinery can increase production and reduce energy consumption.

The energy saving is the only way for the enterprises to enhance economic efficiency and achieve sustainable development, and it is an eternal theme in the production process. The production practice has proved that the advanced technology equipment and process is the fundamental approach to energy saving in China's mining industry.
