Case 3: Cement Application

Case 3: Cement Application

A Robinson customer’s preheater fan had to be shut down every two to four weeks due to excessive vibration. Robinson’s field service team was called in to diagnose the issue and recommend a solution. Through a series of vibration tests, Robinson’s technicians determined that the fan’s support structure was too flexible to handle the excitation caused by the buildup of material on the fan blades.

Solutions:

A series of channels was added to the support base and bearing pedestals at the locations where excessive flexing was occurring.

Result:

The fan now runs significantly longer periods of time and the costs of maintenance and lost production have been reduced.
