Abstract

The invention relates to the field of grinding equipment, and particularly discloses a separator and a grinding machine. The separator comprises a stator and a rotor, the rotor is rotatably connected to the inner side of the stator, a plurality of through grooves are formed in the stator in the circumferential direction, the rotor comprises a top ring, a bottom ring and a plurality of blades fixedly connected between the top ring and the bottom ring, and the top between the rotor and the stator is closed. The grinding machine comprises a machine shell and the separator according to claims 1-6, the separator is arranged in the machine shell, the stator is fixedly connected in the machine shell, a gap is formed between the circumferential direction of the stator and the inner wall of the machine shell, and the top between the stator and the machine shell is closed. The separator and the grinding machine have the effect of improving the powder selecting efficiency.

Description

technical field [0001] The present application relates to the field of grinding equipment, in particular to a separator and a grinding machine. Background technique [0002] At present, jet mills are widely used in ceramic pigments, medicine, biochemistry, PVC, etc. In its working state, the airflow enters the crushing chamber, and the airflow drives the materials in the crushing chamber to be repeatedly collided, rubbed, and sheared to be crushed. The crushed materials move to the separator with the rising airflow. Under the action of the separator, the target particle size The powder is separated, and the powder that does not reach the target particle size continues to be pulverized by airflow. [0003] In the related art, the separator includes a front impeller disk, a rear impeller disk and several blades, the blades are fixedly connected between the front and rear impeller disks and form a circle, there is a feeding gap between adjacent blades, and the inner side of a ...
