MLX Vertical Mill Gearbox

Description

Vertical mills require extremely high rated power and extremely high usability. The gearboxes as the key component of vertical mills are used for transmitting power, reducing the rotating speed of the motor to the rotating speed required by the mill during grinding, and supporting the mill’s millstone. High axial force and partial radial force geuerated during the grinding process are transmitted to the mill foundation through thrust bearing and the housing.

 

Technical Data

Specification: 23
Stage: 2, 1st. spiral bevel gear pair + 2nd.planetary gear pair
Driving speed ratio: maximum i=50
Rated power: P=50~4,000 kW

 

Advantages

Optimized gear meshing accuracy, lower noise, and high efficiency;
Gearbox and planetary frame are analyzed by FEM and optimally designed, ensuring deformation during operational processes is under control for operation smoothness;
The complete thrust bearing device is patented nationally;
Secured manufacturing quality and higher reliability.

 

Applicable Fields

Grinders for raw material; crushing coal sheets in the coal industry and crushing limestone, cement clinker, slag, lime, gypsum, coal ash, and ore in the building industry.
