Test and correctly set VFD or LRS – this prevents the mill starting too fast ...
Sep 17, 2013· For now I am working on a mining project which involves starting two SAG mills, the method of starting these mills is by rotor resistance and likewise we are using an energy recovery system (SER), could someone tell me how this system works SER? each mills have two motors of 8000 kW at kV. thank you for all.
The mill used for this comparison is a diameter by meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 per hour. This type twocompartment mill is a state oftheart shell supported cement finish mill. The torque and time requirements of the mill with the ball
Sep 20, 2019· The SER delivers 100 per cent of rated (nameplate) motor shaft power at above synchronous speeds, an exclusive benefit of this SER technology.

Jul 30, 2015· Critical Monitoring of SAG Mill Electrical Systems. ... pictured below consists of 2x 4 inch Turtle Tough Extreme IR windows and visual viewports installed on the SAG Mill LRS electrical panel. Turtle Tough . This is a critical piece of infrastructure to keep the MILL running and is under extreme load and environmental conditions.
Mill speed can be adapted to upstream and downstream processes – avoids overgrinding, and optimizes load distribution between SAG and ball mill (Mular, Halbe Barratt, 2002). Power consumption is influenced by load respectively torque and mill speed. This means that further energy can be saved if a mill speed below the rate speed is re

Jan 24, 2008· Se que ball mill es molino de bola, pero no se qué sea un molino de bola ¿Hay alguna otra palabra para describirlo? Entiendo que sag es como una depresión, hendidura o caída debida al peso, pero no se en sí que sea ''sag mill''. También quisiera saber qué es ''tower mill'', ya que molino de torre me suena muy literal. Gracias.
Jun 28, 2019· x Full load torque, very typical for a ball mill or sag mill as Chris mentioned. The liquid starter simply adds resistance in the rotor during starting toAppliion of Liquid Resistance Starter ...
• The WRIM + LRS system is causing high transient torques during the startup. Figure 5. The WRIM + LRS is causing high transient torques during the startup. Based on a study done by Anglo Technical Division, presented in a technical paper on the occasion of the SAG 2006 in Vancouver, B. C.
Variable speed was required for the SAG mill. Various options were considered to meet the specified speed range of 65 to 85% of mill critical speed, and the final selection was the IES HyperSynchronous drive Slip Energy Recovery (SER), in conjunction with Wound Rotor Induction motors (WRIM).
We are experts in Slip Energy Recovery Drives (SER Drives), Liquid Resistor Starters (LRS), Static Excitation Systems and Harmonics filters. Find out the solutions we provide our customers for their SAG mills, AG mills and ball mills commonly used in the mining sector.
Grinding plant with SAG and tube mill for Gold/copper ore grinding in is the world''s biggest SAG mill equipped with sliding shoe bearing arrangement and COMBIFLEX® drive system (a favourablypriced alternative to the ring motors normally used with SAG mills of this size).
Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade (~% Ni) and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator (NMK) has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module.
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,, van der Westhuizen,, Mainza, 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.
Starting of the mill is possible by either using two of the 1250kVA sets or one 1250kVA and the 500kVA set. No theoretical analysis had been performed on the system, due to being an existing plant. Commissioning on site involved testing the LRS for the correct resistance to ensure the mill motor would develop ample torque to accelerate the mill.
The Slip Energy Recovery Drive ( Drive) is a technology well proven in the industry for large power motoring systems that allows precise motor speed control at the same time that recover the slip energy in the wound rotor induction motors (WRIM). The typical applications include SAG mill, AG mill and ball mill.
Oct 10, 2008· In 2003, following a competitive tender, Outotec were awarded the contract to supply Kansanshi with a low aspect SAG mill. Not only did variations in ore type and throughput need to be considered in the mill design, but the design also needed to be flexible enough for future expansions at .
