mccord conveyor systems

A major cement manufacturer planned to install a new clinker live storage system utilizing two new concrete silos. The plant contained a transfer conveyor from the plant to the mill building. The conveyor was a 24" belt conveyor fed by an existing bucket elevator.
	The new silos were to be located adjacent to the mill building. We were asked to design a new conveyor system that would increase capacity, allow for the transfer of clinker to the new silos and one that would be environmental sealed to prevent the escape of clinker dust. To add to the challenge, the entire demolition of the old system and the installation and start up of the new system had to be accomplished in a two week window.

We ultimately chose a system utilizing a 9'-0 diameter tubular gallery. The tubular gallery offered an economical alternative for the long spans required and to help control fugitive emissions of clinker dust.
	To control the ambient temperature in the galleries from the hot clinker, we designed and installed a fresh air ventilation system to bring in fresh air and, at the same time, still control dust emissions.

To minimize field erection times, we shop installed all of the internal conveyor sections and mechanical components. The conveyor galleries were field assembled by simply bolting them together at flanged connections. In addition, the conveyor head, tail and take up terminals were shop assembled and aligned.
	The supports were designed with simple pinned connections, an anchor at the tail end and an expansion section at the head end. The installation was completed on schedule and under budget.
