For Ilmenite beneficiation, a combined beneficiation method is often better than a single beneficiation method, which can better improve the ore grade and recovery rate. At present, the combined separation method for ilmenite can be divided into four kind
Cement grinding plant is the final stage in the production of cement, which is separated from the finished cement production units. It mixes cement clinker with other certain amount of mixed materials for grinding, and then produces the finished cement.
Hematite ore is an important mineral resource. With 70% iron content and the large iron output capacity, hematite is the most important iron ore. To improve the comprehensive usage efficiency of hematite, hematite beneficiation process is necessary. We ne
dual pinion solutions were developed to power the mills However realization of the dual pinion solution was only possible when load could be evenly shared between the two pinions When mill diameter and mill power became again increased only the Gearless Mill Drive GMD could be envisaged to cover this requirement above 10 MW
drive application is a dualpinion SAG mill driven by two 5000 kW wound rotor induction motors WRIM Two TMdrive10SPRs control motor speed by recovering rotor current and returning the power to the utility supply Conﬁ gured in a twin motor arrangement the motors share load in the tandem mill The Customer Need

SAG mill product feeds two parallel ball mills of 66 m×111 m internal diameter×length each with a 97 MW twin pinion drive The ball mills are operated at a ball Grinding Mills Girth Gears Pinions Mill Shells Mill
BALL MILL DRIVE MOTOR CHOICES Artec Machine Systems BALL MILL DRIVE MOTOR CHOICES correction capacitors to a dual pinion gear driven mill • Drive 2 A 5000 HP The mill used for this comparison is a 44meter diameter by 136 meter long ball mill with a 5000 HP drive motor It is designed for approximately 90 per hour
SER drives are now mature and ready for use on 2 X 10MW dual drive mills Speed variation required is in the range of 15 of synchronous motor speeds VVVF drive packages from ABB and Siemens are also available for 2 x 10MW in low and high speed options Dual hydraulic inching drives provide a
For both solutions the conventional dual pinion mill drive systems have several significant disadvantages Therefore instead of just copying an existing and rather outdated technology ABB’s target was to have a superior but still competitive dual pinion mill drive system
The Slip Energy Recovery Drive SER 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 WRIMThey are also the dominant technology in wind turbines
