how the grinding mill drive works

Grinding Mill an overview ScienceDirect Topics. The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals this is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls the latter process yields higher quality product as the iron product discharged from grinding mill contains

Case Studies

Each mill has eight rows of 22 hammers (rotated at up to 3,000 rpm) and meshes of 3mm to 12 mm fitted around the diameter to determine the final particle size. Four hundred varieties of processed feed can then be extruded to the required pellet or nut size for a certain animal feed.

Gearless mill drives

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

Literature Review: Gearless Motor Failures

2014-9-10The origins of the failure can be traced back to c. 1994 when PT Freeport Indonesia ordered its first gearless drive for their 34 ft SAG mill. The motor had to fit through a tunnel on the road to the site. This necessitated a change in the frame design from that used in older motors to allow clearance in the tunnel [8].
