When you think of Asphalt you think of Roads. And if you’re in the Midwest you know how important it is to have these plants up and running with all the pot holes.
The asphalt plant is mainly composed of cold aggregate supply system, drum dryer, coal burner, coal feeder, dust collector, hot aggregate elevator, vibrating screen, filler supply system, weighing and mixing system, asphalt storage, bitumen supply system. All these components have characteristics that impact not only the overall quality of the asphalt but also the effect on the environment.
The plant had recently added a new line and had purchased some equipment to be able to make more asphalt to keep up with the demand. This piece of equipment is an exhaust fan for their bag house system. A bag house is a duct collection process through filtering. The blower would exhaust air after the air was passed through the filters section. They wanted us to recondition two motors, machine a new shaft, install new bearings, sheaves, and belts, and then balance the wheel. At the same time the plant ordered Toshiba Drives to run the large blower. These were 2 200HP Toshiba Drives. When the Blower was returned and the drives were installed they got up and running. The customer was thrilled with the work that came from Horner from the repair work to the product.
