The materials are circulated to form a vortex shape, and the materials can be uniformly mixed in a short time. The power of the feeding blade pulp is 22kw, the power of the crushed material blade pulp is 5.5kw, and 200kg can be mixed in 5-15 minutes.

Step three: granulating the mixture obtained in the step two through a granulator 2; the granulator 2 is a twin-screw extrusion granulator and a side discharge type, and because the acidifying agent is solid, basic particles of solid powder are bonded and enlarged by a forced mode (such as extrusion, gravity, centrifugal force, mechanical force and airflow impact force), and a particle group with uniform and concentrated shape and particle size is formed. By adopting the screw structure, the material is extruded under the action of forward thrust of the rotating screw, the extrusion is uniform, and the molding rate is high. The screw motor adopted by the invention has the power of 18.5kw and the granulation size of 0.8-5.0 mm. The emulsion can be used as a binder and forms a coating film, so that granulation is faster and the prepared granules are wet granules.

Step four: sending the particles extruded by the granulator in the third step into a centrifugal spherical shot blasting machine 3 to prepare balls; the centrifugal spherical shot blasting machine 3 consists of a fixed stator and a speed-regulating rotor, and a narrow gap is reserved between the stator and the rotor. The material is put into the container, and due to the rotation of the rotor, the particles are subjected to centrifugal force, air buoyancy blown into the gap between the stator and the rotor and the action of the self principal force to form a regular strand-shaped motion state, so that the surface of the material is compact and rounded. The wet particles are subjected to annular air buoyancy, rotary centrifugal force and self gravity to move in a strand shape around the circumference, so that the ball with extremely high true sphericity is formed.
