there are various high quality and durable autogenous grinder mill here in our factory. As one of chinas leading mechanical equipment manufacturers and suppliers, we also support customized service on autogenous grinder mill. my company make use of the national reform and opening up the opportunity to start with the famous foreign ball ZM series steel slag autogenous mill which is independently developed and manufactured by atairac engineered products inc. mainly is used to separate the steel slag and increase the steel content in the steel slag processing factory. It is also useful for cleaning up the slag on the surface of casting parts in casting factory.
ZM autogenous grinder this series of product is mainly used in autogenously grinding and separating slag and steel to improve the production and grading 87778 email protectedthe ball mill can grind the ore to a finer particle size, but the range of the feed particle size is also higher, and the cost of grinding is higher, so it is usually configured in the fine crushing, as the main grinding equipment, one section grinding commonly used lattice ball mill, the second section grinding commonly used overflow ball mill.
In mineral processing, to make valuable ores realize single separation, ores must be crushed and grinded into powdery materials. In the process of crushing, all kinds of crushers are used, while a variety of ball mills, rod mills and autogenous mills are available in the process of grinding. ball mills and rod mills take steel balls and steel bars as their medium, but advantages cylindrical energy-saving ball mill applied for the minerals grinding the transmission machinery of energy-saving overflow ball mill substitutes larg read more autogenous mill
