Description

Technical Field

[0001] The utility model relates to the field of screening, in particular to an intelligent feeding screening machine. Background Art

[0002] Screening is a mechanical separation method that sorts solid particles by size, and is often used for graded control of powder materials. The screening machine separates particles into different size ranges through the relative vibration of the screen, and can complete a series of process operations, such as removing impurities, separating different particles, grouping and classification, etc. In industrial production and daily life, it is often necessary to remove impurities from raw materials. Screening technology can effectively remove tiny impurity particles, such as metal debris, fiber, plastic, etc. Screening technology can separate particles of different sizes, making it more convenient to handle each type of material.
