The invention provides a crusher and ball mill crushing and ball milling integrated PMB control method. The method is characterized by including the following steps that firstly, adjustment is conducted according to the working conditions of a specific client, abrasion traces and abrasion amounts of a movable jaw plate and a fixed jaw plate are inspected, balance adjustment is conducted, and an engagement angle alpha is found; secondly, under the condition that the engagement angle alpha is kept within the preset range, abrasion of the movable jaw plate and abrasion of the fixed jaw plate aresynchronized; and thirdly, cavity types of different crushing cavities are selected according to the feed size D and the required size d.
