A cane harvesting system which eliminates the use of chain slings has been developed on Illovo's mill-cum-planter estate. A semi-mechanised "split harvesting system" has been adopted. Conventional type trailers are used for infield haulage which off-load loose cane into windrows on the loading banks. Grabloaders then transload the cane from the windrow into "Hilo" cane lorries for transportatio...

Acoustic emission (AE) or vibration signal has been applied in detecting operations of grinding mills many industries. This paper proposes an approach to generate AE signals based on the particle-wall impacts. Through a combination multi-mode vibrations and calibration key parameters, model was able reproduce experimental data. The then implemented into discrete element method (DEM) modelling p...

Over the years, alternative procedures to Bond grindability test have been proposed aiming avoid need for standard mill or reduce and simplify grinding procedure. Some of them use mill, while others are based on a non-standard computation techniques. Therefore, papers targeting propose better claim improve validity, duration, simpler faster methods determining work index (wi). In this review pa...

Abstract During the modeling of grinding systems, population balance (PBM) which considers a constant breakage rate has been widely used over past years. However, in some cases, PBM exhibited limitations, and time-dependent approaches have developed. Recently, non-linear framework traditional linear theory as partial case was introduced, thus allowing estimation product particle size distributi...

Abstract The grain size of clastic rocks is one the most important structural characteristics sediments, which can directly reflect hydrodynamic conditions ancient sedimentary period. preparation conventional rock particle samples usually done by hand wet grinding with a hammer experienced experimenter. For fine-grained rocks, method for preparing has disadvantages long time and low efficiency....

In this study, dry fractionation process was proposed in order to obtain protein-enriched sunflower meal fractions. The includes two-stage grinding using a hammer mill and roll mill, of by sieving. Central composite design (CCD) with four variables on three levels within response surface methodology applied estimate the influence parameters (sieve openings diameter mill: 2, 4, 6 mm, gap: 0.15, ...

A ball mill is a heavy mechanical device and its safe operation affects the entire grinding process. Mill load key index in optimum of process, but it cannot be measured directly. In industrial practice, operational experts normally estimate value based on their experiences signals produced by mill. this paper, we proposed heterogeneous selective ensemble method using multiscale frequency spect...
