The crushing and grinding theory evolves with the progress of industrial level. The crushing and grinding process is closely related to production in each and every industrial sector, such as metallurgy, non-metallic mining, building materials, coal, environment protection field, chemistry, food, cosmetics, papermaking, microelectronics, optics, biology, medicine rolling mill, and ceramics and so on. Due to the rapid development of modern S&T and economy, solid theoretical foundation is laid and superior research environment is provided.

Henan is one of the gathering places of mining machine because numerous processors of small and medium scale crushing and grinding equipment are distributed in Zhengzhou. Nowadays water well drilling rig, competition pressure becomes more and more severe due to the fact that more and more enterprises enter mining machine market. Under this circumstance, Hongxing Machinery still can occupy market to keep sustainable development.
