Case Study - Trona Ore Underground Silo Solution | Jenike ...

The Solution. Jenike & Johanson evaluated the feasibility of reliably handling the trona ore in two 1,300 ton capacity silos to be constructed underground. Flow properties tests on the trona confirmed what most operators knew: when stored at rest trona crystals grew together and formed a hard, solid mass.
