Experts analyze that, the real concrete strength can only reach 40% of the design strength 50 years later, due to high content of super fine cement particle, according to the 60 years general designed service life of concrete structure by now in our country. Vertical mill, as a new grinding equipment with good features of high efficiency concrete batching plant suppliers, energy saving will be the main equipment of cement production, no doubt that it will be more developed and be widely used in the future, and the era of steel ball, ball mill will come to the end. To realize the energy saving of grinding mills, not only by technical innovation, but also by the improving of the management and operation leve of the mill. Few days ago the 5th International Summit on Grinding Mill was hosted by China Cement Net. In the Summit the viewpoint of no ball mill era will coming that put forward by several experts aroused a heat debate in the attendees.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China.

The main quality index of the concrete are the strength and durability, and the concrete plays an important role in concrete structure projects, it is the important guarantee for the durability and safety of the project. The chairman of Jiangsu Concrete Institute said that the quality of concrete is determined by three important factors, they are the raw materials, machinery equipments and related personnels, and the raw materials of concrete are cement, rough and fine aggregate, water, concrete additives, mixed materials and so on, while the most important is the cement Planetary Concrete Mixer Machine, the quality of the cement directly effects the performance of concrete, such as the strength belt type concrete batching plant, durability and the workability and so on.
