Problems solved by technology
The invention adopts the hot air pipe to indirectly heat the material. During dehydration, the material is not in direct contact with the hot air, only the water is evaporated, and there is no flue gas flow. The problem of flying dust; however, when the invention is applied to vacuum dehydration, the mine dust brought out by the rapid evaporation of water and the flow of flue gas cannot be well collected
