Screw Mill/Tahona (83.86): This is a combination that will speed up the tahona process. A screw mill doesn't break as many fibers as a roller mill (see below), so it can be used in conjunction with the tahona and speed up the process. Screw Mill (82.9): When used all by itself, a screw mill is an efficient compromise between tahona and …
