Steel production and demand

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 suitable equipment and milling equipment for recycling are jaw crusher, cone crusher, impact crusher, ball mill, vertical mill, rod mill, trapezium mill and other equipment.
