With the arrival of the peak of the domestic infrastructure building construction, sand and gravel aggregate industry demand for space will be broader, sand making machine is bound to promote the technological upgrading and mass production. Located in the mountain valleys, narrow construction site, the construction of a tight schedule, and a large quantity of concrete works, concrete construction, high strength, With the development of science and technology, more and more countries of the construction of highways, railways and other infrastructure requirements, but also for grain type of aggregate and concrete aggregate gradation have put forward higher requirements.
Henan Unique Industrial new sand making machine is widely recognized as the most advanced sand making equipment, compared with the traditional sand making equipment not only efficient, but also more advanced manufacturing process. Many of the new technologies and the application of new technology to make the device successfully used in highways, high-speed railway, high-rise buildings, municipal, hydroelectric dam construction, concrete mixing station to provide high-quality sand and gravel aggregate, artificial sand making and stone shaping field device of choice.
In recent years, with the continuous development of domestic infrastructure projects, reach 15 trillion cubic meters of sand and gravel aggregates demand around the country mostly natural sand stone, along with the increasing of the project, on the gravel bone material demand is also increasing, concrete technology have become increasingly demanding, especially for high-performance, high-intensity very strict requirements for stone aggregate, annual domestic beneficiation tailings remaining from the beneficiation tail slag processed into sand used in construction, not only to solve the problem of environmental pollution, but also solve the problem of shortage of natural sand, the formation of high economic value.
The artificial sand early in the country is small, artificial sand used in domestic ordinary times during 2000, artificial sand can be divided into coarse gradation can be adjusted in fine three kinds of sand, sand, sand plant with all over the sand making machine made out of sand of varying quality, Henan Unique industries is engaged in the production of mining machinery manufacturers, developed a new type of sand making machine, sand industry in the domestic construction has maintained a leading position.
