Siemens has provided about 80 SIMINE Gearless mill drives to the mining industry since 1980. In these thirty-plus years, SIMINE Gearless mill drives have accumulated a combined total of over 500 years in operation time – and this number is steadily growing even as you read this. This is a benchmark we are immensely proud of.

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 ...
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).

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...
The three SAG mills are configured to operate on either closed or open circuit depending on feed grades. The existing grinding circuit has been in operation since the early 1960's and is show ing signs of significant decay (ore bins), corrosion, w ear & tear on the rotating elements of the mills.
SAG mill control is essentially the stabilisation of mill load (and/or power) and density which can be implemented successfully and very cost-effectively on most modern PLC or DCS platforms. The application of advanced regulatory control is a MIPAC speciality which we have
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
This project is to design and fabricate a mini ball mill that can grind the solid state of raw materials into fine powder. Ball mill is a cylindrical device that used to grind and blend raw ...
The SAG mill was designed to treat 2,065 t h −1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of 74% of critical. The mill is fitted with 80 mm grates with total grate open area of 7.66 m 2 (Hart et al., 2001).
Abstract The paper will present a case where fuzzy logic was the logical choice to improve performances of a semi-autogenous grinding (SAG) mill. The SAG mill stability had to be improved and throughput increased. The process is multivariable, strongly non-linear, and before implementing this system, the operators were actively manipulating many variables with …
SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control …

A gold processing plant I visited recently valued their SAG mill downtime at $130,000 per hour," says Jack Meegan, Global Product Manager for Liners. "Under normal conditions, the return on investment of SAGwise™ total process control is six months, but if we factor in reduced unscheduled maintenance, the return is a lot sooner."
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.,
