The mechanism of sand usually say, is made by crushing equipment made of large stone crushing, sieving, the particle size of the product in accordance with certain technical specifications. Can not be used in river sand, sand well under the circumstances, the mechanism of sand is more abundant resources has become the best substitute natural sand. Moreover, there are a lot of machine-made sand fine performance natural sand is less than the.
First of all, the mechanism of sand than natural sand has larger specific surface area, the strength of concrete with machine-made sand and higher. Secondly, the mechanism of sand production can be combined with the production process of gravel, sand production cost is greatly reduced. Finally, the mechanism of sand is conducive to the comprehensive utilization of mineral resources, not only to solve the environmental problems and improve the utilization of natural resources.
The mechanism of sand sought after by the market, which also makes the upstream industry system sand making machine industry mechanism of sand, also ushered in the development of Dongfeng, Yifan machinery is the rapid rise in the background.
Incoming
Early in the last century ninety's, Yang Anmin is doing technician in the factory, in a study by chance met sand making machine. At that time, the sand making machine application in foreign countries has been very extensive, but in the country also almost can not see it.
If the change of others, may not take it seriously, but Yang Anmin remembered that deeply queer-looking guy, he has a feeling, in Chinese on this piece of land, this machine will play. After consideration, Yang Anmin decided to leave before the factory, embarked on the road of entrepreneurship.
He contacted several former classmates, and tell the sand making machine a considerable promise to them, students also very much agree with his statement, we decided to jointly funded, with running a business, by Yang Anmin served as chairman of the board. Then, in 1998, Zhengzhou Machinery Equipment Co., Ltd. was formally established.
Yifan machinery was established, a Yang Anmin soon rallied to a research and development team, to product development difficult. God helps those who help themselves, 2000, Yifan machinery has been developed successfully Y650 vertical impact breaker (sand making machine), has reached the leading domestic level; on this basis, Yifan machinery built the first use of tailings, the use of vertical impact crusher production mechanism sand production line.
At that time, due to the relatively cheap price of manufactured sand, and provided by Yifan machinery production line production mechanism sand performance has many advantages compared with the natural sand, Yifan machinery soon opened up a market here.
