Vertical Mill Gearboxes
MLX Series
Description
NGC’s vertical mill gearboxes of the MLX, MLXD, MLXSS Series are designed to withstand high torque and extreme conditions. These rugged gearboxes are essential to transmit power, reduce the rotating speeds, and supporting the mill’s millstone. They require high power rating and an extremly high availablility. Higher axial and partical radial forces during the grinding process are transmitted to the mill foundation through thrust bearing and its housing.
