Across-bar cooler is one of the main pieces of equipment in cement production. It is used for the transport and cooling of clinker, one of the ingredients of cement. Cement kilns operate with a cross-bar cooler which consists of four grates driven by a hydraulic station.
At most plants, oil reclamation is not fully supported due to a lack of technical knowledge and availability of technologies, processes and applications. Why should reclamation be considered? The process has evolved over the years through rigorous oil testing and compatibility analysis of in-field trials. The advances and scientific support now available have led to robust reclamation technologies and processes. However, it is important to understand the limits and boundaries.
For a complete and proper lubrication program to work effectively and provide the most return on investment, the entire gamut of lubrication must be considered, ranging from receiving to application.
In the amusement park’s maintenance area, I learned that the park was experiencing a rash of motor bearing failures. With such a long operating history, it was surprising to find this sudden uptick in problems.
There has been much said in recent years about the increased propensity of some modern oil formulations to produce sludge and varnish. Ironically, many of the oils accused of contributing to varnish are the same oils endowed with exceptionally high oxidation stability due to advanced refining technology and formulation science. To better understand this paradox, let’s begin by defining a new term.
