casting hydraulic thrust roller for rotary kiln
Products Description
A thrust roller is a critical component in the operation of a rotary kiln, which is a large cylindrical device used in various industries such as cement production, lime production, and mineral processing for processes like calcination, drying, or roasting materials at high temperatures. The primary function of a thrust roller in a rotary kiln is to support and control the axial movement (thrust) of the kiln.
working principle
Hydraulic thrust consists of thrust roller, hydraulic cylinder and stand. Thrust roller is installed on axis of rolling bearings. Axis is pressed on post moving along the stand and driven by means of hydraulic cylinder. Bearings lubrication is liquid, circulating lubrication is performed by means of individual lubrication system. It is allowed to use lubrication from centralized lubrication system or grease embedded lubrication. Hydraulic thrust cooling is air and natural.
Cement rotary kilns are always 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 short stop. This makes it possible to install the updated technology during scheduled shutdown and optimize kiln availability without loss of production.
