Rotating Equipment

Rotating equipment includes rotary kilns in cement plants, short drum kilns, dryers, asphalt mixers, etc. The cylindrical equipment rotates around its own axis and their riding rings are supported trunnions.

Technical Obstacle

Signs of wear on the trunnions, thrust rollers and riding rings of rotating equipment are a typical appearance due to the metal-on-metal contact. Relatively short operating lives of trunnions, as well as metal flakes next to the trunnion station are a typical indicator of wear. This makes it necessary to lubricate the components. However, classic systems such as large graphite blocks or grease lubrication are not suitable in all cases or do not achieve the desired results. Constantly increasing demands and higher utilization of rotating equipment lead to higher wear rates of moving parts. Factors such as hardness of the material and general alignment of the system play an important role in relation to the service life of certain parts.

A consequence of the wear rate is a shutdown of the equipment for maintenance work like trunnion or riding ring replacement which is associated with costs and downtime. This reduces the overall availability of the systems.

Solution

SPC^® wear protection systems continuously coat the trunnions with a dry, solid protective coating. This coating is transferred to the riding rings of rotating equipment. The protective coating on the interface distributes the surface pressure (further information) more evenly, thus reducing metal wear by up to 80% and resulting in a 3-5x increase in the service life of wheels and rails.

The application of SPC^® systems serves to preventively minimize wear. Necessary maintenance measures such as trunnions replacements are drastically reduced. This results in an increased availability of your rotating equipment.
