Gebr. Pfeiffer supplies two production lines

In 2011, in Barranquilla, Atlántico, Colombia, cement company ULTRACEM SAS was started by the Ruiseco family. The family were the sole-owners of the company. At the time, brothers Juan Manuel Ruiseco Gutierrez (CEO) and Nicolas Ruiseco Gutierrez (Executive Vice President) felt that the Colombian cement market was ripe for a new start-up cement plant, but they were not sure how long the strong market conditions would last. When designing the new plant, it was decided that the company would start with a single production line, but that it would anticipate the addition of a second line at some time in the future.

For this reason, the material storage area and feed silos were designed to have enough capacity for both production lines, assuming that extra space would eventually be needed. This design gamble paid off. As the Colombian cement market continued to strengthen over the next few years, the company was able to proceed with the commissioning of the second production line at the end of 2015, in order to double the company’s production capacity.

Gebr. Pfeiffer supplied the initial line, which featured a clinker grinding mill that was specifically designed to grind a variety of products, ranging from ordinary portland cement to slag and limestone cements. All equipment was delivered within one year of the contract signing, and erection and startup was completed in nine months.

Commissioned in October 2013, the scope of production for line one included the following:

  • A MPS 3350 BC vertical roller mill with patented ‘lift and swing’ technology.
  • A SLS 2900 BC high efficiency classifier.
  • Plant equipment, consisting of a bagfilter, fan, hot gas generator, bucket elevator, weigh feeder, and two conveyors.
  • A feed system with a deduster and metal separator.
  • Various fabricated parts, including a 20 t silo, ducting, dampers, and stack.
  • Instrumentation.
  • Engineering services.

As a result of successful project management, support, and the execution of the first line, UTLRACEM had the confidence to stay with Gebr. Pfeiffer for the additional supply of the second line. The initial OEM guarantee for production line one was 65 tph, but the plant was actually able to produce almost 100 tph. For production line two, ULTRACEM wanted to duplicate these increased production levels.

In order to keep within the safety parameters of the equipment, it was agreed to increase the size of both the gearbox and the mill motor for each of the production lines. The only changes in scope between the first order and the second was the increased capacity of the gearbox (from 1750 kW to 2000 kW) and the mill motor (from 1750 kW to 1950 kW), and an increase in the number of packing plant spouts up to 14 from the eight that were initially installed on production line one.

The current rates of production are listed as follows:

  • Mill production from line one:
    • Structural cement up to 70 tph.
    • General use cement up to 90 tph.
  • Mill production from line two:
    • General use cement up to 90 tph.

To date, ULTRACEM is pleased with its average production rates, as it continues to expand its market share in the region.
