摘要
A landplaster production method includes the steps of providing a supply of particulate gypsum material, drying the gypsum material by passing a stream of heated air thereby as the material is rotated, classifying and separating the dried particles into fines and coarse particles, collecting the suspended fines in a collector, passing the coarse particles to a grinder such as a roller mill for reducing the particles, and mixing the reduced particles with the collected fines for processing into landplaster. The elimination of fines from the feed to the grinder results in significantly greater production by increasing the efficiency of the grinder. Further, the dryer is modified to agitate the dried gypsum material so that it may be more easily introduced into the classifier/separator situated adjacent the drier discharge outlet.
