Cement milling Question 1 Recently we have changed the grinding balls in the second chamber of our mill to a lower size balls The effect is a 10 per cent of reducing in fineness at the discharge of the mill therefore the efficiency of our separator is better but we were waiting for an increase in the production nevertheless it is the same than past periods with bigger balls... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
