Jul 31, 2014· The following modified Bond equation was proposed for crushing (Magdalinovic, 1990): Wc = cP A Wi ( cP 10 - cF 10 ) (8) where: Wc - is energy consumed for clinker crushing (kWh/t), Wi - is Bond ball mill work index (kWh/t), Pc -is sieve size passing 80% of the clinker after crushing (µm), Fc - is sieve size passing 80% of the clinker before ....

Bond Work Index In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution His theory and index were introduced in a widely cited 1952 journal article Bond called his theory the "third theory of comminution", counting ....

Cement grinding optimisation

Based on the above considerations for crushing and grinding, the energy consumption for the clinker pre-crushing and ball milling can be estimated using the following Bond based model: (9) W = W c + W m As pre-crushing product size P c is equal to the mill feed size F 80 then: (10) W = A F 80 W i 10 P 80-10 F c ,...
