The invention provides a dry-method electrode forming method and forming equipment, the forming equipment comprises a feed port, a discharge port, a high-pressure air chamber, a non-linear flow channel and a calendaring device.The dry-method electrode forming method comprises the steps that a dry powder mixture of an active substance and a binder is put into the feed port, fluidized under the action of high-pressure carrier gas and enters the non-linear flow channel to move at a high speed, and the non-linear flow channel is formed; and in the process, continuous friction and collision with the inner wall of the runner are generated for further mixing and fibration of the binder, spray is formed through release of a discharge port, and an electrode is formed through deposition and calendering. The method is simple in technological process, mixing and impacting of the active substance and the binder material can be efficiently achieved, the fibrosis effect of the binder is improved, and the electrode quality i
