GN Separation, a professional manufacturer specializing in solid-liquid separation and fine screening equipment, has recently completed production, factory acceptance testing and delivery of its high frequency stack vibrating screen for a major domestic mining enterprise, to support fine ore classification and slurry dewatering in its mineral processing circuit.
This self-developed stack vibrating screen adopts the two-degree-of-freedom resonance principle, driven by dual vibration motors as a unified excitation source. It can be configured with 2–5 stacked screen decks as required by on-site ore characteristics. The stacked layout greatly saves plant footprint compared with side-by-side single-layer screens, which is ideal for mines with limited workshop space.
Integrating high-frequency fine screening technology and multi-deck stacked structure, the equipment targets typical pain points of fine mineral separation: screen blinding, poor classification precision and low single-unit throughput. Its adjustable high-frequency vibration effectively disperses fine ore slurry, improves screening accuracy for fine fractions, boosts mineral recovery rate and cuts overall power consumption per ton of ore processed. It is widely suitable for iron ore, lithium ore, ilmenite and other non-ferrous/ferrous mineral wet classification and dewatering scenarios.
Before shipment, the equipment passed continuous running inspection, vibration detection and sealing test at GN’s workshop. The on-site technical team will provide installation guidance, commissioning and operator training after arrival.
“As domestic mineral processing plants keep upgrading toward finer grinding and more efficient separation, the demand for reliable fine screening equipment keeps rising,” said the project engineer from GN Separation. “Our stack high-frequency screen balances compact layout, high capacity and stable running, to help mining customers lower operation cost and optimize beneficiation indicators.”
GN Separation’s stack vibrating screen series has been deployed in multiple domestic and overseas mining projects, gaining consistent recognition for rugged structure, easy maintenance and flexible customization.
