details on raw material. the mixture must contain a defined ratio of calcium oxide, quartz, aluminum oxide, and iron oxide as required for clinker production. calcium oxide is contained in various types of limestone but also in marl, shelly limestone, or chalk. to add aluminum oxide to the mixture, clay is used as a rule.

chrome ore ball mill for wood our company has been devoted to mining machinery for 40 years. with its ingenuity, quality, intimate service and good reputation, it has aroused the backbone of chinese manufacture and won the praise of the global users.
ball mill product from 56 to 60% in the green pellet mix. the raw materials used for the preparation of the green pellets are iron ore, limestone, bentonite and corex sludge. iron ore þnes and limestone þnes of 10 mm size were ground together in laboratory ball mill by maintaining the þneness 2 325 as mentioned above
ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns. the size reduction technique involved here is attrition and impact. in ball mills, hi-chrome steel balls are used to grind the raw material. the ball mill is located horizontally rotating about the horizontal axis.
the ball mill is the key grinding equipment after the material is crushed, and then the material is ground into mineral powder or ore pulp. the common processed materials: quartz, feldspar, gold ore, silica sand, limestone, etc
first chamber of cement and raw mill : energosteel. high quality steel grinding balls for mining. the energosteel is a leading manufacturer of the european quality steel grinding balls … increase grinding fineness of raw … of steel balls for ball mill to … grinding media steel balls, hardened steel media, 1 to12 mm.
this paper mainly introduces the raw mill in cement plant. in order to achieve the desired setting qualities in the finished product, a quantity 2-8%, but typically 5% of calcium sulfate usually gypsum or anhydrite is added to the clinker and the mixture is finely ground to form the finished cement powder. this is achieved in a cement raw mill.
