pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of the SAG/AG grinding mills. The general arrangement of AG/SAG mills discharge system is shown in Figure 1. BREAKAGE DISCHARGE Figure 1: Schematic of a typical sag mill operation.
SAG Mill Pulp Dischargers Grinding amp; Classification Circuits Metallurgist amp; Mineral Processing Engineer. Whats your opinion for TPL (turbo pulp lifter) for SAG mill? It seems that by adding a TPL could help increase energy efficiency and reach the SAG mill maximum capacity.

Pulp dischargers of many parts The steel dischargers on the SAG mill comprised 187 pieces. Not unsurprisingly, this led to lengthy downtimes for component replacement. Making the situation worse: the discharger service life was a relatively short 12 months.
Classification efficiency can also affect the result. pulp lifter restrictions, further adversely affecting circuit performance. Achieving fine grind sizes in single capacity is too high for a single SAG mill, a two stage grinding or alternate circuit is generally recommended. 4

Mill relines No discussion of milling, and particularly SAG milling, would be complete without some mention of relining. Unlike a concentrator with multiple grinding lines, conducting SAG mill maintenance shuts down an entire concentrator, so there is rightly a tremendous focus on minimizing required maintenance time; reline time represents the majority of scheduled maintenance requirements.
LG A mill power equation for SAG mills. Minerals and Metallurgical Processing. Feb 1990 pp5762. Gross power No load power Net power drawn by the charge () The net power is calculated from Net power e! c./ Watts () In equation, D is the diameter inside the mill liners and Le is the effective length of the mill including the
#0183;#32;The SAG Mill is a machine added by Ender uses Micro Infinity (#181;I) to grind (or mill) items into their crushed variants, like Ores into SAG Mill has four output slots; recipes can have 14 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in
there has been a shift of emphasis on ball mill optimization to semiautogenous grinding (SAG) mills. In order to optimize this section, the of grate/pulp lifter design in AG/SAG mill discharge. understanding in terms of discharge rates and grate classification in relation to mill
As pulp lifters control the mills throughput, performance and efficiency are an integral part of the AG/SAG mill. SPH modelling can simulate the complex flow behaviors in the pulp system and provide insights into how we can optimise the flow inside the pump chamber, decrease recirculation and wear, and increase slurry filling.
Since the early 1980s, we have been designing and manufacturing SemiAutogenous (SAG) and Autogenous (AG) Grinding Mills under the FullerTraylor brand. Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the
and slurry from the discharge grate out of the mill. Hence, the design optimisation of pulp lifters affects not only the energy efficiency and throughput of autogenous grinding/semiautogenous (AG/SAG) grinding mills, but also contributes other process benefits such as improved wear life and operatorfriendly steady and smooth mill operation.
Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20100 mm). Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed
