A ceramic pipe grinder for food grinding processing solves the problems that in the prior art, the idle grinding area is large, the material discharge resistance is large, the grinding efficiency is low, the processing capacity is small, the processing effect is poor, the wear-resisting property of grinding discs is poor, the service life is short, and the application range is narrow. The ceramic pipe grinder is characterized in that a movable grinding disc and a semi-open type vane wheel are installed at the shaft end of a motor shaft extending into a shell, a fixed grinding disc is installed in a fixed grinding disc installation clip clutch, the joint surfaces of the fixed grinding disc and the movable grinding disc inwards form an internally-concave cone-shaped grinding cavity, a fixed grinding disc adjusting seat is connected with an adjusting nut in a threaded mode, the internally-concave conical surface of the fixed grinding disc is provided with symmetrical step-shaped oblique teeth, and the internally-concave plane of the movable grinding disc is provided with material guide grooves and trapezoid teeth. The ceramic pipe grinder for food grinding processing has the advantages that the fixed grinding disc and the movable grinding disc have the synergistic action of extruding, smashing, shearing and grinding on foodstuffs, the wear-resisting property is good, the manufacturing cost is low, the service life is long, the whole machine production efficiency is high, the production capacity is large, and the requirements for ultra-fine processing, dry material slurrying and industrialized continuous production can be met.
