Mineral Fabrication was contracted to build 3 coal storage silos and 11 lime storage silos over six months for Graymont. We equipped each silo with reinforced closed-in tops to support a conveyor system with cone-bottom discharges. The silos also had to support vibrating discharge feeders at the bottom of the structure. We transported the silos with specialized trailers to the Graymont facility and erected them on site.
