GN Solids Control is pleased to introduce its high-frequency stack vibrating screen supplied for a domestic mining company. Developed independently by GN, the stack vibrating screen is designed for wet screening, classification, and dewatering of fine-grained materials in mineral processing, coal preparation, and other industrial applications.
The equipment adopts a multi-layer screen box configuration, with 2 to 5 screening layers available to meet different site requirements. Driven by dual vibration motors, the machine operates based on the two-degree-of-freedom resonance principle, generating linear motion of the entire screen assembly. This design provides high screening efficiency and processing capacity while reducing energy consumption and equipment footprint.
Polyurethane screen mesh is used for its elasticity, wear resistance, and resistance to blinding. With an open area of approximately 28%–45%, the screen panels support efficient fine-material separation, with an average service life of more than six months under suitable operating conditions.
The equipment also features a modular feeding box with adjustable installation height, internal material distribution plates, and multi-level buffer structures. These designs help distribute feed evenly, reduce material impact on the screen surface, and improve wear protection. In addition, the polyurea resin coating provides enhanced abrasion and corrosion resistance in material-contact areas.
With its compact structure, reliable operation, and convenient maintenance, GN's high-frequency stack vibrating screen provides an effective solution for fine-material wet screening and dewatering in mining operations.
