<p>An alumina digesting apparatus, comprises the following devices: high pressure diaphragm pumps, double-pipe preheaters, pulse buffers, autoclaves with heating tube bundles, autoclaves and flash evaporators. The devices are connected successively by pipes according to leaching process. The apparatus enhances the output of alumina from 450kt/year by existing apparatus to above 500kt/year, so that productivity could be enhanced.</p> |
