The extrusion forming of cylindrical strip material, in the high speed rotating centrifugal wheel broken broken teeth cut, growth degree of equal short cylindrical particles (and cylinder diameter with a certain proportion). Rotary centrifugal force, the particles with a tooth plate, wall and the friction between particles, and the gas between wheel and material cylinder thrust the combination of all particles in three-dimensional spiral rolling, forming rub evenly, make particles quickly rounded into a ball.……

Powder material under the action of impeller, collide with each other scattered half flow state, and achieve fully mixed. With the injection of glue, is wet powder by mixing oar and compared.in extrusion, rub and knead to form a loose soft wood. Chopped knife chop the soft material to form a small and uniform wet particles.……

Roll crushing machine is using the material of water of crystallization, the powder directly degassing preshrinking, the hydraulic roller extrusion materials produce binding force between the molecules and form embryo piece, then through crushing granulation, grading dust recycling technology were made into particles that could satisfy the requirement of users. Often used in the pharmaceutical industry, thermal sensitive material under water unstable easy decomposition of drugs, can also be used in food, chemical industries such as dry granulating, method is simple, save work time.……

Material in air force under the action of fluidization and mixing, becomes a fluidized state. But the fluidized state is irregular, not under strict control. This is different from the bottom injection and tangential injection. Liquid medium by nozzle top-down injection, the direction and material movement in the opposite direction. By the surface tension of liquid medium of liquid bridge, powder material together, form a volume expanding, eventually forming a certain size of particles, and under the action of thermal drying.……
