Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often the ball used in ball mills is oversize "just in case". Well this safety factor can cost you much in recovery and/or mill liner wear and The method is used to size a cement ball mill. Efficiency correction factors are applied with the Bond equation. The method is valid both for clinker grinding and for raw materials grinding. This method only gives a rough and initial idea for sizing a cement ball mill.

During cement grinding the clinker is ground with other ma-terials (gypsum limestone natural pozzolan or industrial by- data and equations to evaluate the different component of this. For the calculation of water quantity for concrete first of all we have to find the quantity of cement. Just assume that the required volume of cement for the mix is 100 kg and W/C is 0.4. Water Quantity = Water-Cement Ratio x Volume of Cement. Water Quantity = 0.4 x 100 kg = 40 liters / 100 kg cement or (20 liters / 50 kg cement bag).

How Cement Is Made

After the clinker is cooled cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Cement production will experience several procedures which include raw materials blending process and burning process cement clinker grinding process and packaging process.

CementThe major cements composition and properties

Waterproof cement is the name given to a portland cement to which a water-repellent agent has been added. Hydrophobic cement is obtained by grinding portland cement clinker with a film-forming substance such as oleic acid in order to reduce the rate of deterioration when the cement is stored under unfavourable conditions. Masonry cement in contrast with Portland cement requires additional lime. To account for this the IPCC Guidelines provide an equation based on masonry cement production parameters to estimate CO2 emissions resulting from the additional lime. The equation is illustrated below. EQUATION 2 CO2 (tons) from CaO added to masonry cement =
