DERRICK SCREENS STUDY
Krech Ojard & Associates has provided a derrick screens study and engineering services for a large pellet plant operation in northern Minnesota. Their product is taconite pellets, sold and shipped to steel plants around the world. In the concentrator building, crushed ore is milled and screened to extract concentrate for pellet production.
This process uses vibratory screens to size the milled ore. The plant currently uses ten derrick screens in the concentrator.
Krech Ojard provided engineering services for a derrick screens study which would improve screening rates and efficiency. This study included the development of 3D models to aid in visualization of the equipment and spaces.
