Abstract
A crushing apparatus crushes a supplied material into the form of a fine powder. The material is supplied into a crushing tank while disposing the crushing tank within the processing tank. The supplied material is crushed within the crushing tank and then is discharged to the interior of the processing tank through the axial flow pump member and an axial flow promoting member. During operation, the material is continuously circulated within the processing tank in a manner passing through the crushing tank, whereby crushing is performed in such circulating process. Since the axial flow pump member is provided at the lower portion of the crushing tank, the material in the inclined casing is guided axially downward to generate an axial flow when the inclined vane is rotated. A pumping effect is provided by the axial flow. The crushed material is sucked to the side of the inclined casing and then is emitted downward. When the axial flow promoting member is provided at the lower portion of the crushing tank, it is possible to strengthen the sucking force within the inclined casing. The material within the inclined casing is actively discharged by the rotation of the turbine vane positioned at a downward opening portion of the inclined casing.
