Following the upgrades in the SAG mill circuit sampling and modeling of the ball mill circuit identified a bimodal hardness characteristic of the ore Evaluation with both MetCom and JK SimMet lead to changes in the ball make up size from 75 mm to a 5050 mix of 75 mm and 38 mm Cortez Mine – Results Achieved

An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ball mill on grinding and classification performance of a hybrid high pressure grinding roll HPGRmulticompartment ball mill cement grinding circuit Mass balance of the circuit was done by JKSimMet Steady State

Computer simulations were performed to assess performance of two proposed new circuit flowsheets The first proposed flowsheet consists of existing SAG mill circuit and a new proposed ball mill in closed circuit with a new second hydrocyclone package The second

An example of a typical flotation circuit with the sampling points labelled according to type of sample required and priority of sample is illustrated in Figure 1 The bulk of this paper considers the sampling requirements for each stream in some detail as a basis for assessing the sampling requirements of any plant during the design phase

EF2 Open Circuit Grinding when grinding in open circuit ball mills the amount of extra power required compared to closed circuit ball milling is a function of the degree of control required on the product produced The inefficiency factors for open circuit grinding are given in Table I

GRINDING CIRCUIT DESIGN FOR ADANAC MOLY CORP USING A GEOMETALLURGICAL APPROACH in a SAG and Ball mill circuit where there the other In this case any ore with a high BWi value will have reduced throughput due to the ball mill despite the capability of the SAG mill to handle more and vice versa when the SPI value is high

In this study an extensive sampling study was carried out at vertical roller mill of ESCH Cement Plant in Luxemburg Samples were collected from mill inside and around the circuit to evaluate the

Following the upgrades in the SAG mill circuit sampling and modeling of the ball mill circuit identified a bimodal hardness characteristic of the ore Evaluation with both MetCom and JK SimMet lead to changes in the ball make up size from 75 mm to a 5050 mix of 75 mm and 38 mm Cortez Mine – Results Achieved

Ball mill was crashedstopped for inside mill sampling in survey1 after completing of the circuit sampling Both compartments of the ball mill were sampled by approximately 1meter along the long axis of the mill from an approximate depth of 40cm below the mill ball charge level Mill inside sampling locations are tabulated in Table 3 Table 3

The first proposed flowsheet consists of existing SAG mill circuit and a new proposed ball mill in closed circuit with a new second hydrocyclone package The second 11 Grinding circuit sampling A sampling campaign from grinding circuit was planned to assess its performance under the current operating conditions Presently

sampling campaigns were carried out aiming to produce mass balances and provide material for laboratory tests The parameters determined in the laboratory tests were used to predict by simulation the circuit behavior with a low ball charge level and a balanced ball size distribution Keywords Grinding simulation optimization ball mill

SAG mills are the main workhorses in the majority of comminution circuits globally They need to be fed and kept working round the clock But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear the sound of the mills standing still

primary wet autogenous mill WAM and a series of ball mills WAM is customary chosen either based on examination of analogous equipment specifications or from the evidence of very expensive commercial and semicommercial testing that requires large sampling much time and high investment 1 The current practice of exploratory design of ore pre

The circuit consists of a two compartment ball mill and a dynamic air classifier There is a slotted diaphragm inside the ball mill that separates the two chambers from each other The particles coarser than the size of the slots 10 mm stay in the first chamber while the finer particles pass the second chamber for further size reduction

In this configuration a multichamber ball mill was operated as closed circuit with an air classifier Design parameters of the circuit are presented in Table a result of the mass balancing studies the tonnages around the circuit and the measured and the calculated size distributions are presented in Fig 2 Fig 3 Download Download fullsize image
