Wet Concrete Hopper
Case Study Outline:
Application: 192 cubic feet wet concrete batching hopper divided into 2 compartments. Complete hopper was lined.
Liner: TIVAR 88-2
Bulk Material: Wet concrete, coloured.
Problem: Concrete would adhere to steel hopper walls and cause disruption in flow. Labour intensive to clean out hardened concrete regularly.
Background:
A major paving stone company was concerned about rejected product and high cost to manufacture specialty concrete pavers.
Problem:
The wet concrete mixture would adhere to the steel hopper walls. This resulted in a plugged discharge and incorrectly poured pavers. Hardened concrete was almost impossible to clean out of hopper.
Solution:
TIVAR 88-2 liners were engineered and fabricated to fit into existing steel hopper. Due to narrow hopper discharge all corners were field welded to seal liner.
Result:
Large steel making facility was concerned about slow downs in production.
IMPORTANT: After the TIVAR 88-2 liners were installed, most of the sticking problems were eliminated. Quality and production counts were up significantly due to proper flow through the lined hopper. A secondary benefit of no colour contamination between batches was also realized.
