Sawmill DC Motor

Last summer, we received a call from the maintenance manager of a large sawmill. To get an idea of equipment size, this large bandsaw cuts 6’ diameter tree trunks into quarter pieces. A large carriage carries the log and feeds it into a large bandsaw with a blade that is 12” wide. The quarter pieces then go to smaller saws to cut slab boards. The complaint was that the large DC mill motor was making noise. Our field service supervisor, Jim Delawder, investigated and found that the banding on the commutator end of the armature had fractured and was flopping against [...]

Finish Ball Mill Motor

A 1350 HP Synchronous Motor out of a cement plant in Ohio was called out to bid and Horner won that bid. This finish mill motor comes out of a cement plant in the ball mill. The ball mill is a big round pipe that is full of steel balls the size of a softball. As the pipe turns it has blades welded on the inside which carry the balls up to the top of a 16-foot diameter pipe and the balls fall to the bottom of the pipe where the rocks are. The weight of the balls smash the rock [...]

Keeping a Plane Safe at 35,000 Feet

Aircraft Engines are the beating heart of an airplane. We, as passengers expect them to run free of mechanical errors and keep us safe in the air no matter what happens: bad weather, geese, etc. The manufacturers of these engines test them extensively to make sure they are built well. Horner gets to be involved somewhat in keeping those testing facilities up and running. An aircraft engine manufacturer needed repair and maintenance on a 6,000 HP Compressor Motor. The compressor furnishes air for testing aircraft engines. It is run on a Dynometer which we have also repaired in the past. The [...]

Aluminum Plant Outage

In June of 2017 an Aluminum plant contacted us to begin the early planning stages of their outage which was scheduled for January 2018. The customer was about to undertake the most involved outage on their primary mill and wanted Horner’s exclusive involvement. The outage was a success despite the very large scale and daunting tasks assigned. All work was coordinated by Ralph Coonce of field service. If you’ve ever seen Ralph in action during an outage I don’t have to explain that he doesn’t just show up. He’s elbow deep in the actual work turning wrenches or any another task [...]
