A system and method for reducing roller skew, which involve ascertaining first and second thrust load properties applied to a roller while a rotary body rotates in opposing rotational directions, and adjusting an orientation of at least one bearing assembly for the roller until an amplitude difference between the first and second thrust load properties is below a predetermined threshold.

high loaded rollers and to counteract timely with adequate adjustment, the so-called roller skewing. The Thrust Load Meter is an ultra-precise inclinometer which is specially made for the application on large bearing housings as on rotary kilns. The sensor simply needs to be bolted to the bearing housing without opening it.

- Second step considering shifting rollers on 2nd support. - Final step is to shift the rollers on 3rd support. 4.4 After the whole adjustment the Kiln axis and the rollers' torsions will be corrected( pages 11 and 12 ). 4.5 The "crank" could be wind up (liquidated) by cutting the Kiln's shell off …

Own to the rotary kiln such as cement kiln, lime rotary kiln and shaft kiln is widely used in building materials, chemical industry, nonferrous metallurgy industry, black metallurgy, and refractory materials.Rotary kiln's support roller is an important module, and it has the character of large bearing load, poor working environment, constant running, and complex maintenance.

Problem: Support Roller FailureSolution: Understanding SkewWHAT IS SKEW? WHY SKEW ROLLERS? WHY IS PROPER THRUST IMPORTANT?

Support Rollers & Support Bases for Rotary Equipment. Your rotary equipment has multiple rolling surfaces which require proper support and pin point accurate adjustments. Issues with support base structures or its mechanical components may cause excessive wear throughout the unit. Industrial Kiln & Dryer® has the capacity to design, repair and ...

A prerequisite for the normal operation of a rotary kiln is the alignment of the rotation axis of its shell. Its curvatures even within the tolerance (2–3 mm) cause intensive wear of tires, support rollers and their bearings, increase the

re Rotary kiln supporting roller adjustment. 1. Axial thrust on all supports, specially middle one. 2. First support mentioned is towards preheater side or outlet side? 3. Check the previous readings if doing regularly to assess the impact of uneven coating inside kiln. 4. Check for temp at particular support.

Rollers skewing control (bearings thrusts position when kiln is in downhill) Hydraulic thrust pressure control (downhill and uphill) Girth-gear inspection in operation (teeth temperature, contact pattern) Inlet and Outel seal visual inspection.
