TIVAR88-2 Liners Eliminate Flow Restriction & Adhesion in Gypsum Hopper.
Liner | ​TIVAR 88-2 |
Application | 14' x 12' Heavy Wall Steel Hopper |
Bulk Material | 6" Minus Gypsum Rock |
Problem | ​Major sticking of mud and fines causing large rock to jam. Damage to hopper caused by using impact to clear material jams. |
Background: A national drywall manufacturer struggles to achieve consistent flow of large gypsum rock into process through a number of heavy duty steel hoppers. | Problem: The mud and fines of the gypsum rock are sticking to the sloping steel hopper walls. The build up of mud and fines is creating a course surface and blocking the hopper discharge causing the large rock to clog the hopper, resulting in 'blanks' in the feeder conveyor being fed by the hopper in question. |
​Solution: Our team identified TIVAR88-2 as the ideal material to line these hoppers. Custom lining systems were engineered and fabricated to fit into the existing steel hopper and discharge chute. The steel hopper was re-worked and TIVAR88-2 liners were installed including with radius corners to eliminate corner sticking. | ​Result: After the liner is installed the buildup and sticking problems have been eliminated allowing for the gypsum rock to flow freely into the feeder conveyor, eliminating blanks on the conveyor.After 3 years of operation, the liners have shown minimal wear and are still in use. The production staff has noted a substantial amount of labour savings in regards to monitoring and cleaning the hopper. |
