The Challenge
Ostara needed to convey recovered struvite fertilizer prills within confined wastewater treatment facilities. Preserving the prills’ size and shape was essential to their performance as a slow-release fertilizer. The conveyor also had to fit the available space and control spillage to protect valuable product and limit cleanup.
The Solution
UniTrak supplied a customized TipTrak TT500 bucket conveyor to transfer dried prills from the dryer to the classifier. Its interlocking buckets supported gentle handling and product containment, while its compact footprint accommodated the restricted layout.
The conveyor incorporated four application-specific modifications:
- Extended support legs to shorten the product’s drop from the dryer and reduce dusting.
- Rubber inlet skirting to guide material into the buckets.
- A bucket knocker to assist product discharge.
- A transition chute connecting the conveyor discharge to the classifier inlet.
The Results
Ostara reported that the customized solution simplified material handling and was easy to install and maintain. In the 2016 case study, the company confirmed that it had standardized on TipTrak equipment across its sites in North America and Europe.
“UNITRAK’S ABILITY TO PROVIDE A CUSTOMIZED, EASY TO INSTALL AND MAINTAIN SOLUTION HAS MADE THE MATERIAL HANDLING ASPECT OF THE PROCESS MUCH SIMPLER AND OSTARA HAVE NOW STANDARDIZED ON THIS EQUIPMENT AT ALL OF ITS SITES IN NORTH AMERICA AND EUROPE.”
