CASE HISTORY 2

Brick Making Plant

So. Carolina, USA

Casing Diameter: 10 inches
Elevation: 20 feet
Rate per hour: 36 tons
Material: Manganese Dioxide

PROJECT DESCRIPTION

A leading U.S. brick maker sought to replace an existing bulk material elevator used to refill a Loss in Weight (LIW) feeder with Manganese Dioxide (Mn02). Their existing conveyor caused excessive aeration of the Mn02 which interfered with the operation of the LIW feeder. The customer required a minimum flow rate equivalent to 28,000 lbs/hr to a height of 15 feet. The elevator would be used only for short duration runs while refilling the LIW feeder.

Olds Elevator tested samples of the customer's Mn02 in the Olds lab and designed and built a 10-inch diameter Olds elevator for the job. The elevator was installed and put into service. The problem with aeration was eliminated and the LIW feeder is refilled with 200 lbs of Mn02 in 10 seconds (a rate of 72,000 lbs/hr).
