Launched in 1969, ABB variable speed drives control the core variables of the motor and adapt its speed and torque according to the precise needs of the application. Equipped with a revolutionary ABB technology called Direct Torque Control , the drives calculate the state of the motor at phenomenally high speed.
Motor Technology for Mining Applications Advances Coal Age. China Mining 2012 Conference and Exhibition especially in underground coal mining applications. Likewise drive systems are evolving from fixed to variable speed.
Mining Monthly. HPGRs consist of two counter rotating rolls, one ˛ xed and the other ˝ oating. ˜ e ore is fed from a hopper into the gap between the rolls for crushing at high pressure. ABB variable speed drive systems enable the grinding rolls to operate at optimal speed and provide accurate load sharing between the two rolls.
We have a long history of providing speed control solutions for a variety of mining applications including tailings pumps, underground ventilation fans, ore conveyors, bucket elevators, and centrifuges. Our CSA/UL approved team of engineers can create custom solutions suited to the specific needs of each mine.
SIMINE Conveyor consists of powerful mechanics and motors, variable speed drives as well as durable geared drives or highly efficient gearless drive systems. All components are most reliable, letting you benefit from high system availability, low operating costs, and maximum productivity.
The variable frequency drive application is a dual pinion SAG mill driven by two 5,000 kW wound rotor induction motors . Two TMdrive 10SPRs 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.
From the conveyor belts of the mineral, crushers, size selecting screens for the crushed stones to even on the air filtering systems , the variable frequency drives can be used with significant gains both in energy saving and in the increase of equipment production as well as in reducing mechanical breaks and stops for maintenance.
