Suitable for classifying fine materials and wet sticky materials with a mesh size of 10-140
When it comes to classifying fine materials and wet sticky materials with a mesh size of 10-140, traditional screening equipment often falls short: fine particles clump, wet materials stick to screens, and separation precision drops sharply. To solve these pain points, a recent test of the high-frequency vibrating screen proved this equipment is a game-changer—delivering both efficient separation and precise classification that meets the strict demands of industries like mining, construction, and aggregate processing.
The test focused on two core material types: 10-140 mesh fine quartz sand (a common raw material for glass production) and 20-80 mesh wet sticky clay-sand mixture (often encountered in construction waste recycling). From the start, the high-frequency vibrating screen stood out with its unique design: a high-speed vibration motor (operating at 3,000 RPM) and a wear-resistant polyurethane screen mesh that resists clogging—two features critical for handling wet sticky materials. Unlike conventional screens that rely on low-frequency shaking (which lets fine particles settle and stick), the high-frequency vibrating screen uses rapid, small-amplitude vibrations to keep materials in a "fluidized" state, preventing clumping and ensuring every particle contacts the screen.
For the fine quartz sand test (targeting 10-140 mesh classification), the high-frequency vibrating screen showed impressive efficiency. The feed rate was set to 5 tons per hour—higher than the 3-ton limit of traditional screens for the same material. Yet the high-frequency vibrating screen processed it seamlessly: within 30 seconds of feeding, the screen separated the sand into three grades (10-40 mesh, 40-80 mesh, 80-140 mesh) with a precision rate of 98.2%. Lab tests confirmed that each grade had minimal cross-contamination—far exceeding the 95% precision requirement for glass production. “Traditional screens would take twice as long and still have 5-8% impurity in each grade,” noted the test engineer. “The high-frequency vibrating screen cuts processing time while boosting precision— that’s a double win.”
The wet sticky clay-sand mixture test was even more revealing. Wet sticky materials are notoriously hard to screen, as clay clings to screen meshes and blocks gaps, forcing frequent stops for cleaning. But the high-frequency vibrating screen’s rapid vibrations broke up clay clumps, and the polyurethane mesh’s non-stick surface prevented adhesion. Over a 2-hour continuous test, the screen processed 8 tons of wet mixture (20-80 mesh target) without a single clog. The separated sand had a clay content of just 0.3%—well below the 1% limit for concrete aggregate use—while the removed clay was collected as a separate byproduct (suitable for brick making). This not only solved the clogging problem but also turned waste into a usable resource—something traditional screens could not achieve.
Another key advantage of the high-frequency vibrating screen highlighted in the test was its adaptability. By adjusting the vibration frequency and screen angle, the equipment easily switched between classifying 10-mesh coarse fine materials and 140-mesh ultra-fine materials—no need for time-consuming part replacements. This flexibility is crucial for small to medium-sized enterprises that handle multiple material types.
In conclusion, the high-frequency vibrating screen test confirmed its status as a top choice for 10-140 mesh fine and wet sticky material classification. Its efficient separation (handling higher feed rates with no clogs) and precise classification (meeting strict industry standards) address the biggest pain points of traditional screening equipment. For industries looking to boost productivity, reduce waste, and improve product quality, the high-frequency vibrating screen isn’t just a piece of machinery—it’s a reliable solution that delivers consistent results.
