The University of Queensland Abstract and Figures Discharge of pebbles, finer rock, ball scats and slurry from mills and its Spherical balls are the dominant grinding media used in ball mills However, balls which are initially spherical, wear into non STARTLING EFFECT OF BALL SCATS REMOVAL ON SAG
Reasons your ball mill could be scatting heavily: Too large a feed Not enough grinding media Too small a grinding ball (what size is your?) Inside these Sag/Ball mill are big steel balls that grind ore via an impact process In simple terms, these hard metal steel balls get to the top of Dealing With Scat in Mill Processing PumpEng
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls An internal cascading effect reduces the All ball mills do have this area, although it differs in size The odd shape of the scats prevents this media to have a rolling/grinding effect in the mill Only eat away on the mill Odd shape of wet ball mill ball scats Grinding & Classification

The ballmill may lack sufficient impact energy to effect breakage of these particles, which are referred to as ‘scats’ They may find their way into a ballmill circuit 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 Combined DEM and SPH simulation of overflow ball mill
The ballmill may lack sufficient impact energy to effect breakage of these particles, which are referred to as ‘scats’ They may find their way into a ballmill circuit as a result of wear of the trommel or due to a deliberate change of the aperture size, to increase SAG mill throughput EgFor the DEM setup of the ball charge, the mill chamber is initially filled with a 34% volumetric fill of ball sizes ranging from 32 to 65 mm The full ball size distribution is given in Table 3 The number of particles in the DEM part of the model is around 135,bined DEM and SPH simulation of overflow ball mill

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ballmilling, was revisited in this investigation, using a normal spectrum of pebble sizes (19–75 mm) Batch tests in a pilotscale mill (057 m diameter) were used to compare ballmilling to various ball/pebble mixturesAn increase of over 10% in mill throughput was achieved by removing the ball scats from a single stage SAG mill These scats are non spherical ball fragments resulting from unevenBall scats removal rate From a 25t drum of scats 1275
Ball mill ends usually have ribs to lift the charge with the mill rotation The ribs prevent excessive slipping and increase liner life They can be made from white cast iron, alloyed with nickel (Nihard), other wearresistant materials, and rubber (Durman, 1988)The ball mill Ball milling is a mechanical technique widely used to grind powders into ne particles and blend materials18 Being an environmentallyfriendly, costeffective technique, it has found wide application in industry all over the world Since this minireview mainly focuses on the conditions applied for the prepBall milling: a green technology for the preparation and

Reasons your ball mill could be scatting heavily: Too large a feed Not enough grinding media Too small a grinding ball (what size is your?) Sometimes, you solve scatting by charging the ball mill correctly (I saw cases where the After mining the ore, mills use small steel balls to grind it smaller for further processing To assist with loading and unloading of these steel balls, they use a kibble system More importantly, this provides a safe and Kibble system (Back up ball charging) Dynamic Engineering
