The artificial principle of the tumbler screen is a kind of high efficiency screening machine specially designed to meet the needs of a large number of high-precision screening. It is currently the most effective effective principle for simulating manual screening motion, and it meets all fine and ultra-fine powder and particulate materials, and is especially suitable for materials that are difficult to handle. Due to the low frequency working mode of the swing screen, its noise is less than 75 decibels, but because some materials have strong adsorption, easy to clump, high static electricity, high precision, high density, and light specific gravity materials, they are very easy to be screened. In order to prevent the blocking of the screen from affecting the screening efficiency, the swing screen will be equipped with a unique triple cleaning setting: ultrasonic cleaning, bouncing ball cleaning, and rotating brush cleaning.
