The stationary magnetic assembly, approximately 28 in. long, covers an arc of about 210°, and attracts chips and scats to the inside diameter of the barrel. As the ball mill slurry discharges through the barrel, eight strategically placed lifters inside the barrel carry the ball fragments to the top, where they fall onto a sloping discharge chute.
TRUNNION MAGNET WITH BALL MILL DISCHARGE The trunnion magnet is an enhanced system for separation and removal of balls, chips or scats in a typical ball or SAG mill operation. The trunnion magnet is mounted at the SAG ball mill discharge point and is used in place of a trommel screen.
Startling Effect Of Ball Scats Removal On Sag . worthwhile removing the scats even though some balls were included in the rejection stream.Ball size distribution the ball load in the mill, prior to the removal of the scats, was calculated from the volumetric filling, taken from the full grind-out to be 70t.The average scats size distribution was taken from the 6 test runs, figure 7.
minerals from gangue ore. Ball mills are widely used to achieve this objective, however, ball breakage as well as wear and tear of balls generate a dead load within the mill. Chips and scats (ball fragments) typically recirculate through the mill until they are finely milled and move on to the next step in the process.
This results in a product size of around 76mm – 88mm per ball. There is a minimal number of non-round balls or scats/rock per tonne. Current industry partner (minesite) has been using Interquip's second hand Grinding Media / Mill Balls for the last 8 years. Product can be supplied in drums or in bulk.

removing balls, chips or scats in a typical ball/SAG mill operation. This technology replaces the dead weight of ball magnets with fresh ore. By effectively removing an estimated 80% or more of worn or broken media, a trunnion magnet reduces power consumption from the mill drive and prevents expensive damage to other equipment.

The blind trommel is a short extension that bolts directly to the discharge flange of the ball mill. The function of the blind trommel is to transport the mill discharge material through the magnetic field. The blind trommel is fabricated from stainless steel and has an abrasion resistant wear liner. The magnet sector is comprised of permanent ...

The primary mill liner design allowed for pebble porting and a dedicated scats crushing circuit processing the ejected +80mm material and recycled this back to the SAG mill feed. The Ball mill operated in closed circuit with several vibrating screens, with the circuit designed to treat 1875tph of Uranium ore delivering a product of P80-350um.
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 ...

The effect of scats on ball-mill productivity was tested and it was concluded that scats may not have an adverse effect on productivity in secondary ball-mills and composite mills, if large balls are present. The use of a trommel on the ball-mill is suggested to solve related problems in the classification circuit.
The Sepor Batch Ball Mills are constructed of 304 stainless steel (wetted parts), with structural steel frame and support structure. The rugged forged steel trunnions with hubs provide support for the shaft and give structural support for the mill ends. The mill is machined to provide a true alignment of the mill.

The oversize rock (SCATS) is caught by the trommel, along with the worn hardened steel balls. This material is fed past a magnet (12) to separate out the steel balls. The oversize rock passes through the SCATS cone crusher (13), prior to passing once again into the SAG mill (4) for further grinding.
Abstract. Discharge of finer rock, pebbles, ball scats and slurry from mills and its flow through trommels and into other processing operations all affect the performance of overflow ball mills. Modelling of the coarser rock components and the grinding media is best done using the Discrete Element Method (DEM) while modelling of the slurry ...
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
Sometimes, you solve scatting by charging the ball mill correctly (I saw cases where the mill was up to 15% under power). Other times, you need to enlarge the ball size diameter ie: using a 75 mm ball instead is 35 mm. Other times, you must control and reduce the feed size (crushing circuit product).
The recirculating load in a ball mill circuit affects the final product size as well as the formation of scats/ejection of balls from the ball mill. The variables in a ball mill and cyclone should be optimized continuously to maintain a good recirculating load. Exercise 9 in Demo: Cyclone Feed.
circuit comprises a primary jaw crusher, SAG mill with a cone crusher on mill scats and a ball mill with a single pack of cyclones in closed circuit with the ball mill. During the first decade of operation the mill was capable of processing in excess of 410 tonnes per hour (450 tons per hour) and was largely ball mill limited ...
Ball scat is fragments of grinding balls that result from using porous grinding balls. 30t of scats were removed from a total charge load of 70t. Surveying and modeling the mill revealed that the breakage rates had increased dramatically at the coarser end of the size distribution. An increase of over 10% in mill throughput was achieved by ...
