Tyres with floating shims
Floating shims are machined and the sizing is so that the clearance in operation be optimum. Local stress to the mechanical parts is avoided and the ovality is low enough to keep bricks stability: in QATAR, the lining under the tyre could last more than 2 years.
Pinion and girth gear
The girth gear is linked to the kiln shell by flexible ties.
The pinion and gear assembly is lubricated by a very reliable paddle wheel system.
Roller stations
The sturdiness and good behaviour of Fives FCB roller stations
is ensured by: swiveling of the bearings at each end, the use of Main Metall(R) bearing which accept high loads, a direct and efficient water cooling, a trouble-free lubrication system.
Thrust roller
A sturdy thrust roller assembly ensures a scanning movement of the tyres on the rollers thus equalising the wear.
