Fabricated Plate Pre-Heater

The product highlighted here was built for use in a limestone processing facility, it was designed as a pre-heater used to heat limestone prior to processing. Measuring 20' in height, 50' in diameter, and weighing 200,000 lbs. the unit was constructed of abrasion resistant (AR) plate, A-36 carbon steel, and stainless steel, in thicknesses varying from .375" to 1.500". All of the raw materials where cut using CNC burning which offered the advantages of accuracy and maximized the use of materials. All of the components where formed to the customer supplied drawings, and received extensive visual and dimensional inspections. Assembly was completed using flux core arc welding (FCAW), the unit then had a coating of zinc primer applied. It was fully assembled in our shop to verify fit and dimensions; then dismantled into 12 sections for shipping. To learn more about this project, see the table below or contact us directly.
