subject: The Duty-cycle Operation Of Steel And Iron [print this page] Shandong Province is a large province of steel production and demand, since the reforming and opening up, the steel production scale have expanded, iron and steel production have increased significantly year by year. Because of the limit of iron ore resources and geological conditions, combined with iron ore large investment, long construction period, high production costs, low returns and other reasons, iron ore production capacity of Shandong province is obviously insufficient, capacity, quality, quality can not meet growing demand.Whether it is the Shandong province, or other provinces, it is widespread on the recycling of tailings output control and the situation is not in place. Manufacturers generally only know that mass production can guarantee the demand of steel production, but easy to overlook the use and management of tailings and the reason is that the understanding of the iron ore tailings recycling is not enough for them. China"s iron ore tailings grade is usually between 6% -13%, up more than 20%, if they can recycle the iron, the number is considerable. There are many methods to recovery the iron ore, but it can not leave from the crushing and grinding. Currently the most crushing equipment and mill equipment mainly have Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing. It is located at the High & New Technology Industries Development Zone of Zhengzhou,China with an area of 50 thousand m2 which includes 15,000 m2 of standard heavy duty industrial workshop. Equipments are more than 160 pieces, including large and medium sized metal processing, riveting and installing equipments. There are more than 660 workers including 80 administrators with secondary and senior occupational titles and engineering technicians. In order to promote the competitive strength, the advanced technologies have been introduced from America, Germany, Japan and Australia, which established the international advanced production line, first-class modern testing base as well as research centers of sand maker, mill and mine-selecting equipment. Scientific management, advanced processing technology and innovative manufacturing theory make the company become the mining machinery manufacturing and exporting base in China.
jaw crusher, cone crusher, impact crusher, ball mill, vertical mill, rod mill, trapezium mill and other equipment.In order to response to the call of our country about the solid waste disposal, Henan Hongxing Mining Machinery Co., Ltd . developed and researched a variety of solid waste handling equipment, including jaw crusher,impact crusher, cone crusher, Crusher Series (sand making machine), and high pressure suspension grinder mill, high pressure micro powder mill and other equipment to meet the solid waste disposal in the sound, reduction and recycling.
