  • Two Stage SAG Grinding Circuits VS ABC Circuits

    Grinding facilities are arranged either as single-stage circuits, or in a two-stage configuration with ball mills. Another major concentrator, designed with an autogenous mill, ball mill, crusher (ABC circuit), is presently under construction and scheduled for start-up late this year. The host rock of the Island Copper deposit is a highly fractured fine-grained andesite. A prominent alteration

  • Model:Raw Bond/Barratt SAB & SABC Model

    Raw Bond Model. This is a SAG or AG mill plus ball mill model that estimates the specific energy consumption (E SAG) using the 1979 Barratt equation and the classical Bond work index equation including Rowland efficiency factors.The model allows a manual calibration factor on both equations (CF SAG and CF ball, respectively).This formula usually gives higher total circuit specific energy

  • Page 1 Page 2 INTRODUCTION SAG Metallurgy OMC

    compared to the reduced requirement of a two stage grinding circuit (SAB/SABC) with singular feed system. Depending on the ore characteristics and the target grind, the constraint is likely to limit the capacity of a single train with a pinion driven mill to ranges of 4 8 Mtpa. Similarly, rod mills are limited to around 1600 kW in size because of the maximum size of quality steel rods and

  • SABC Grinding Circuit Operation & Optimization

    When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted

  • AN OVERVIEW OF SINGLE STAGE AUTOGENOUS AND

    Single stage mills appear to be reasonably power efficient at coarse grinds, but become very inefficient at grinds less than 75 µm. The grind size is more difficult to control in a single stage SAG circuit at fine target grind sizes, when compared to an SAB or SABC circuit.

  • Selection oof Comminution Circuits for Improved Efficiency

    • Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of 0.5 to 2 Mt/a. • SABC circuits are typically selected for plants above 2 Mt/a treating moderate

  • Difference Between Sag Mill vs Ball Mill mech4study

    Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place. The basic principle of mill machine is that when any

The collective experiences earned from designing, operating and debottlenecking these various

  • Optimizing your SAG mill operation International Mining

    In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports
