Choosing a SAG Mill to Achieve Design Performance

2021年1月11日 Choosing a SAG Mill To Achieve Design Performance. John Starkey1, Principal Consulting Engineer Sami Hindstrom2, Manager, Grinding Travis Orser2, Project Manager, Grinding. Starkey Associates Grinding Design and Process Engineering 336 – 268 Lakeshore Rd. E. Oakville, Ontario L6J 7S4 PH: (905) 465-7512 Fax (905) 844-5297.2019年11月14日 Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pin-ions, 3.7 MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used two4.47 MPa (6000 hp) motors to drive a 1I-m-diam x 4.5-m long (36-ft-diam x 15 ft) autogenous mill. However, recent SAG mill designs Mill drive selection for semiautogenous grinding mills2015年1月1日 In Fig. 3, Fig. 4 the data is presented in order to show the effect of the fresh feed size, particularly the % −6″ +1″ (−152 +25 mm), on the SAG mill power consumption (Pc) in kW and on the SAG mill specific energy consumption (Ecs) in kW h/t, obtained by dividing the power consumed (kW) by the fresh feed rate (t/h).Modelling SAG milling power and specific energy

Inferential measurement of SAG mill parameters III

2002年12月1日 This paper discusses inferential measurement models for semiautogenous grinding (SAG) mills. Inferential measurements of SAG mill discharge and feed streams and mill rock and ball charge levels are obtained utilising process measurements and recognised process simulation models.2018年3月1日 Generic SAG mill geometry and operating conditions. SAG mills can have diameters up to 12.9 m. A three-dimensional slice of a generic intermediate size 8.4 m diameter SAG mill is used here. This study was performed using a series of DEM simulations whose details are given in Table 1. Different combinations of fill level, lifter Development of models relating charge shape and power draw to SAG mill ...The various options available for large-horsepower semiautogenous grinding (SAG) mill drive systems are examined, together with their impacts on mill design and relative capital and operational costs. A brief history of large-mill drive systems is given. State-of-the-art mill design and mechanical design considerations are also discussed. A design for fixed Selection criteria for SAG mill drive systems IEEE Journals ...
