Ball mill maintenance projects main content

    mill widely used in all walks of life, the machinery industry in the ball mill to a better understanding of the ball mill ball mill essential consumables, ball mill ball how to make use of it? A close relationship, how to judge the size of the ball and the main motor current.Experienced mill miners in the ball mill operation, all the time to observe the ball mill the current changes. No change to the amount of ore in the mill, and in good working order, in general, the current the higher the ball mill ball more volume; the contrary, the less. Xingbang technical staff through the wet 36004000 lattice-type ball mill, long-term experimental observation was informed that the mill supporting synchronous motor voltage is 6000 volts, AC frequency is 50 Hz, the power of 1100 kilowatts, rated current 125A.Motor idling current is 0; motor driven ball mill empty alicey599  load running current 25A; when the amount of ore milled to 60t / h of ball 60t, synchronous machine current is 85A; when the ball mill to the mine the same amount, the ball increase 5t, the current increases 4A; 5t / h when the amount of ore to increase the ball the same amount, the current increases 5A. Second, how to add the ball of the ball mill and a new installation or after maintenance: the new look for the ball mill liner is a running-in process.

    The first to add a ball accounted for 80% of the total ball of the ball mill.Different types of ball mill the number of ball, the ball not the same size ratio.Such as the maximum amount of ball MQG15003000 ball mill for 9.5 ~ 10t, first loaded ball 7.5 8t,jaw crusher the rest of the ball until the ball mill drive 3 to 4 days plus; ball weight ratio of 100 mm 40% of 80 accounted for 30%, 60 mm accounted for 15% 40mm 15%.MQG36004000 mill the maximum amount of ball 70t,[brick making machine:http://www.xbm-aac.com] the first time installed 56t, the remaining 3 to 4 days plus, the proportion of ball 120 mm accounted for 40% of 100 mm accounted for 30% of 80 mm accounted for 15% of 60 accounted for 15%.Generally speaking, the ball mill in more than 2500 in diameter, ball size and proportion 120 mm accounted for 40% of 100 mm accounted for 30% 80 accounted for 15%,jaw crusher 60 mm 15%.; For the mill diameter of less than 2,500 , the first ball is 100 accounted for 40%, 80 accounted for 30% of 60 mm accounted for 15%, 40mm accounted for the 15%.The ball mill is operating normally, the additional ball diameter as follows: ball mill of more than 2500 mm in diameter,rock crusher additional ball for 120 mm; mill diameter less than 2500 mm, additional ball 100. According to the quality of steel balls,Hammer crusher under normal circumstances for every one ton of ore additional 0.8 to 1.8 kg.
