Description
Technical Field
[0001] The utility model relates to the technical field of whole-grain screening, in particular to a whole-grain screening integrated machine. Background Art
[0002] Granulator is a kind of equipment used to process the granular materials in the raw materials to make them uniform in size. It mainly processes the raw materials by grinding, pressing, cutting, etc. to achieve the effects of uniform particle size, regular shape, smooth surface, etc. Granulator is widely used in grain processing, chemical industry, pharmaceutical industry and other fields.
[0003] The principle of screening is to use the aperture size of the screen to classify the granular materials according to size. Smaller particles can pass through the aperture of the screen, while larger particles cannot pass through, thus achieving the purpose of separation. Common screen forms include rectangular meshes, circular meshes, square holes, slot holes, etc. The whole particle screening machine can screen the materials and separate the granular materials according to different sizes. Through screens with different apertures, the materials can be effectively divided into particles of different sizes to meet the needs of different uses.

[0024] A moving wheel 111 for the moving plate 110 is installed on the bottom side of the moving plate 110. There are four moving wheels 111, which are installed in a rectangular array on the bottom side of the moving plate 110. Support rods 112 for supporting the device body 120 are symmetrically installed between the device body 120 and the moving plate 110.
