What is the Thrust roller for rotary kiln
The thrust roller is an important auxiliary part of a rotary kiln. It is designed to control the axial vibration of the rotary kiln, so that the tyres and rollers can be evenly distributed on the full width. At the same time, it can ensure the linearity of the kiln body centerline, make the big and small gears mesh well, and reduce the power consumption of the kiln process.
Rotary kiln is subjected to a natural down thrust due to their inclination. The down thrust is absorbed by the thrust device – hydraulic or mechanical. The function of the thrust device is to transfer the axial load from the rotary kiln to one or several supports and to maintain the rotary kiln in the axial position. Retrofitting of an existing older model of thrust device or a non-Valmet model to either a mechanic or hydraulic thrust device can be done during a shortstop. This makes it possible to install the updated technology during the scheduled shutdown and optimize kiln availability without loss of production.
