Pebble Crushing in SAG Mill Circuit 911 Metallurgist
Jul 21, 2018 The pebble crushing test circuit as originally designed extracted a minus 76 mm (-3 in.) product from the fully autogenous mill through 76 mm (3 in.) square discharge grates. A vibrating screen was used to provide a mill discharge product
Dynamic modeling and simulation of a SAG mill-pebble
Oct 01, 2018 Below all the simulation results are from SAG mill 1. The first graph shows that the throughput of the SAG mills is affected by the pebble crusher settings. A cone crusher with settings like CSS = 28 [mm] and speed = 280 [rpm] gives coarser product than a cone crusher with smaller CSS and higher eccentric speed.
Dynamic modeling and simulation of a SAG mill-pebble
The hypothesis put forward in this paper is that active control of the cone crusher’s eccentric speed and closed side setting (CSS) can increase throughput and/or energy efficiency of the SAG circuit. To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit was implemented.
SAG mill and Pebble mill Grinding & Classification
Actually the oversize of screen after AG or SAG mill is called pebble and then the cone crusher in this circuit is called pebble crusher. SAG mill is Semi-Autogenous Mill which there is up to 15% ball inside and AG mill is Autogenous Mill which there is no ball inside the mill. Hope it helps. Hassan

DYNAMIC MODELLING OF A SAG MILL-PEBBLE CRUSHER CIRCUIT
In a semi-autogenous grinding (SAG) mill and pebble crusher circuit, the behaviour of the comminution process is non-linear and time-varying due to wear and variations in the feed material. To describe such a complex system, data-driven models were introduced, along with a case study of a SAG mill circuit in Copper Mountain, British Columbia, Canada.
INVESTIGATION OF SORTING TECHNOLOGY TO REMOVE
of an autogenous mill. Similarly, Mosher, Banini, Supomo and Mular (2006) suggests that pebble crushers, in general, should be designed to accommodate 25-35% of the new SAG feed tonnage. HPGR (High pressure grinding rolls) have also been considered to treat pebbles as part of an AG/SAG circuit.

What's the Difference Between SAG Mill and Ball Mill
Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
USING THE SMC TEST® TO PREDICT COMMINUTION
Crushers have one index: M. ic. HPGRs have one index: M. ih. For tumbling mills the 2 indices relate to “coarse” and “fine” ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits. “Coarse” in this case is defined as spanning the size range from a
Crusher
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Mill (grinding)
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
