  • An analysis of mill grinding noise ScienceDirect

    An analysis of mill grinding noise ScienceDirect

    Jan 01, 1985 The noise generated by a ball mill during a batch grinding operation is investigated and the results show that, for a given ore, the noise levels may vary with time of grind, ore charge weight and mill speed. The role of the ore in absorbing noise energy is suggested as a possible control variable for the grinding process and as an indicator of ... read more

    Stirred Media Detritors SMD Metso Outotec

    Grinding Media. The grinding media can be varied with a wide range of alternatives, depending on the application and the process requirements. Grinding media plays an important role in grinding efficiency and mill liner wear life so a high-quality media is beneficial, but an economical solution is also important. read more

  • SAG Mill Optimization using Model Predictive Control

    SAG Mill Optimization using Model Predictive Control

    Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009). read more

  • Control SAG Mill sound detection Grinding

    Control SAG Mill sound detection Grinding

    Where I work now, Minera San Cristobal in Bolivia, we use sound control on both the SAG and Ball Mills. The result of this control is a 25% increase in throughput, over the plant design, with a 10% reduction in energy consumption; the mill is more efficient. The mill control manipulates the feed rate and mill speed depending on ore and liner conditions. Liner wear has improved and ball consumption has decreased. Great job Pueblo Viejo keep focused on this control … read more

  • Grinding Mill Control Types Grinding amp Classification

    Grinding Mill Control Types Grinding amp Classification

    The required sound level (DB) is entered manually as a set point into the Expert System, the sound of the mill charge motion is measured by 4 microphones adjacent to the SAG Mill shell, and the resulting signal is transmitted to the Expert system which, in turn, sends a set point to the SAG mill tonnage and speed controller. read more

  • Grinding Mill Control Grinding amp Classification Circuits

    Grinding Mill Control Grinding amp Classification Circuits

    The Control philosophy controlled to a mill load set-point by automatically adjusting the ore feed rate, and the acoustic control controlled the mill speed. This is all a commissioning exercise and one of the things we wanted to do was - incorporate an additional loop whereby mill speed is automatically adjusted to control mill weight/load. read more

  • Hammer Mill Noise Control eNoise Control

    Hammer Mill Noise Control eNoise Control

    This operation can be very noisy and loud. eNoise Control provides noise control solutions appropriate for hammer mills. Material is fed into the mill’s chamber typically by gravity. The material is struck by ganged hammers (rectangular pieces of hardened steel) which are attached to a shaft which rotates at high speed inside the chamber. The material is crushed or shattered by the repeated noisy hammer impacts, collisions with the walls (which can create outdoor environmental noise … read more

  • How to Operate a Grinding Circuit

    How to Operate a Grinding Circuit

    Apr 25, 2016 Sound of Mill. Loud, metallic rattle: Mill is nearly empty of muck; balls banging each other and wearing out liners. Raise feed, cut head water if necessary. Increase classifier water to build load. Thick mushy sound. Quiet: Mill choked with muck, not grinding. Cut down feed, increase head water carefully. Cut classifier water a little. #4. Ball Mill Drive Amps read more

Even though process control can be considered as a mature technology for a mature industry with benefit to the operating and economic performance of a process, three main problems face the mining, mineral and metal processing industry in terms of process control: the design of accurate process models ... read more

  • SAG Mill Process Control Grinding amp Classification

    SAG Mill Process Control Grinding amp Classification

    The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for cycling or surging that indicates instability in … read more
