United Taconite(CNR) Balling Drum Replacement Forbes, MN

Project Description: Krech Ojard performed a feasibility study at United Taconite to improve their taconite balling process. The project involved the replacement of two existing ten foot diameter drums with two twelve foot diameter drums, reworking feed and takeaway conveyors, and replacing the existing roll screens with wider, longer roll screens.

The current equipment is difficult to maintain with limited access, so a key element of the design is to improve access to the new equipment. 3D modeling of the entire balling process was the approach taken by Krech Ojard to tackle this problem. Working with plant operations and maintenance personnel, existing plant drawings, and some field measurements; a design has been developed that will allow greater productivity and the new larger equipment to be placed with improved access for maintenance within the confines of the existing structure.
