## Converting a ball mill from overflow to grate discharge

Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters This is different to an overflow mill which holds the slurry and balls inside untilThe components of the mill that rotate on bearings are the trunnions The trunnion is a kind of cylindrical and tubular shaft with thick walls, wherein the ore passes through its inner diameter, both in the feed and in the mill discharge Download : Download fullsize image; Fig 2 Trunnion bearing components, including bronze bushingAnalysis of the criticality of flaws found in trunnion ofIn the drawings FIG 1 illustrates a preferred embodiment of the invention providing reducing and pulverizing mill 10 of the ball or tube mill type Mill 10 includes a hollow shell 12 mounted for rotation about a horizontally disposed, longitudinal axis by means of opposed trunnion bearing assemblies 14, 16TRUNION LINER AND SEAL FOR ROTARY MILLS

The trunnion is the main ponent in the ball mill equipment which is both the inlet channel and the end cover of the ball mill and carries the rotation of the cylinder Continuous operation under alternating stress the wear is relatively large especially the trunnion at the inlet and outlet ends is prone to breakage and slurry leakageBall mill ABSTRACT The discharge end design of a ball mill plays an important role in discharging the desired particle sizes (−150+10µm) and the percentage of recirculating load from the discharge end of the ball mill In continuous wet ball mills, the composition of feed (hard ore or soft ore) to the mill varies continuously, leading to unA comparative study on a newly designed ball mill andThe ball mill that best suits your respective application depends of the finished product in the ball mill discharge Shellsupported ball mills are becoming the mills of choice over those with trunnion bearings Depending on the size of the mill, there are two, four or six sliding shoes per bearingIndustrial Solutions polysius ball mills

## Features ERIEZ

The Trunnion Magnet separator was developed and improved over the years to remove grinding ball fragments directly from the mill discharge This separator mounts to the discharge flange of the ball mill An arc of permanent magnets attracts essentially all ferrous material in the discharge stream and removes it from the process This magneticThe trunnion magnet consists of a barrel or “blind trommel” that is mechanically attached to the trunnion or discharge of a ball mill The barrel rotates around a fixed assembly of ferrite and rareearth magnets, positionedMagnetic Separation Technology Can ImproveGround material exits the mill through the discharge grate which prevents grinding balls from leaving the mill A proportion of material, mostly fines, is „„air swept‟‟ out of the Ball mills (Fig 11) are coming in cement plant areas of raw Trunnion bearing mills having mill heads & trunnion that isDESIGN AND ANALYSIS OF BALL MILL INLET CHUTE FOR
