The invention discloses a manufacturing method of dry-press anisotropic ferrite. The method comprises the following steps: carrying out two-stage wet milling on a permanent magnetic ferrite presintered material; putting the slurry obtained by two-stage wet milling into a drying box, and drying; screening the dried material blocks to prepare magnetic powder, adding an adhesive, mixing in a dry-type stirrer, pulverizing by a high-speed pulverizer, and screening to obtain the dry-press anisotropic ferrite powder; pressing the dry-press anisotropic ferrite on an experimental press to obtain a steel magnet, and applying an impulse-type heavy current onto a coil to generate an instantaneous high-impulse magnetic field; and carrying out degumming treatment, and sintering. The powdery camphor can be directly sufficiently mixed with the magnetic powder; the impulse-type heavy current enhances the degree of orientation of the dry-press anisotropic ferrite magnetic powder; the additive is beneficial to enhancing the coercive force of the product; and the dispersing agent enhances the particle size uniformity of the ground magnet powder, and enhances the properties of the dry-press product.
