ball mills are commonly used in the manufacture of portland cement and finer grinding stages of mineral processing, one example being the sepro tyre drive grinding mill. industrial ball mills can be as large as 8.5 in diameter with a MW motor, drawing approximately 0.0011% of the total worlds power (see list of countries by ball mill professional ball mill,magnetic separator,flotation machine,dryer. henan fote heavy machinery Co ltd.is a professional manufacturer and exporter specilized in the prodution of ball mill, magnetic separator, rubbletyred mobile crushing station, dryer, jaw crusher, rotary kiln and other large mining machinery
design process An attritor ball type mill was designed at the laboratory scale so that its construction could be done with materials and technology available in the region.this project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into fine powder. the cylindrical jar is used as a mill that would rotate the
yanacocha gold single stage sag mill design, operation, and optimization ball mill work index 15.7 to 19.2 circuits to process gold and silver ores from a mixednov 18, 2008 We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. introduction ball mill is an efficient tool for grinding many materials into fine powder.
ball mills are predominantly used machines for grinding in the cement industry. although ball mills have been used for more than one hundred years, the design is still being improved in order to reduce the grinding costs. holtec has undertaken performance optimisation of the cement grinding circuits by doing processthe values of modified bond ball mill work index for the product of agsag mill varied from 18.68 to 23.04 kwht. the highest ore hardness in the process of ball mill grinding is noted for sample no.1, the lowest for sample no.4. also it is important to note, that the value of
