Ball mill reject project

Coal-mill reject is an industrial waste product produced from coal during ball mill grinding mostly in thermal power plants. Every day in a plant of capacity 500 MW about 40,000 tons of coal is used for making powder by ball mill for use in firing of boilers to produce steam. Out of this about 2% coal is very hard which remains ungrounded

    problem with increased quantities of rejects from ball

    Is this a new mill with an ungraded ball charge? All the balls could be wearing out at the same time (if it is ball chips being rejected). Are you maintaining ball charge at a set volume or using mill power draw to maintain the charge? Have you inspected the grate to make sure it is still in good shape? Regards. Todd

    Slurry exiting the ball mill will pass through the ball mill trommel and report to the cyclone feed hopper. Reject oversize material from the ball mill trommel screen will be collected in the ball mill scats bunker. Media will be added to the ball mill to maintain the power draw as required, using the ball mill ball charging kibble and hoist

    Odd shape of wet ball mill ball scats. - Grinding

    Our wet Ball Mill griding media reject (scats) from the trommel screen is an odd shape ( see photo attached). I’m not use to this wear shape of grinding media in a ball mill. Normal wear of grinding media in my experience is down from a spherical to a non-spherical (egg shape) or a homogenic spher
