Autogenous Welding definition. Autogenous welding is a technique of fusion welding process where welding is performed without the welding electrode or filler material. Note to mention that Autogenous welding is not similar to SMAW, GTAW, or MIG/ MAG etc.; but instead, it is one of the techniques of the existing fusion welding processes.

The term autogenous grinding came about due to the concept of self-grinding of the ore. It is also referred to as "Run of Mine" or ROM grinding. A sturdy, rotating drum throws larger rocks of ore in a cascading motion, causing impact breakage of similar smaller rocks that need to be ground into finer particles.

ABSTRACT The present invention relates to a method for comminuting a coarse lump of mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction which are determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a …
