FIELD: material grinders; chemical, food-processing and pharmaceutical industries; construction engineering. ^ SUBSTANCE: proposed disintegrator has vertical reservoir with fixed knife-type cutting members mounted on inner surface of reservoir over helical line and rotary grinder mounted on hollow shaft and also provided with knife-type cutting members. Reservoir is isolated from surrounding medium and is filled with low-boiling cooling agent; lower part of hollow shaft is engageable with reservoir. Knife-type cutting members of reservoir and rotary grinder are located over helical line at pitch reducing towards reservoir bottom and their cutting faces are made in form of elliptical torus. ^ EFFECT: enhanced grinding of material. ^ 6 cl, 3 dwg |
