GS Series — Tangle-Free Screening
GS Series shaftless roller screen — no center shaft structure for tangle-free fine screening of sticky and fibrous materials.
GS Series shaftless roller screen — no center shaft structure for tangle-free fine screening of sticky and fibrous materials.
The shaftless roller screen is a specialized screening equipment featuring a unique no-center-shaft design. Unlike traditional drum screens that rely on a central rotating shaft, the GS series uses individually driven rollers arranged in a curved or straight line to form the screening surface. This design eliminates the problem of material winding around the shaft, making it ideal for screening sticky, fibrous, or stringy materials that would clog conventional screens. The rollers rotate in the same direction, conveying material forward while fines pass through the gaps between rollers. This design achieves high screening efficiency with minimal clogging, low noise, and easy maintenance. The shaftless roller screen is widely used in sand and gravel classification, waste sorting, coal grading, and construction waste recycling, handling materials with high moisture content and sticky characteristics that are difficult for conventional vibrating screens.
The moving jaw retreats, increasing chamber volume, and material feeds into the chamber by gravity.
The moving jaw advances, compressing and shearing the material between moving and fixed jaw plates, causing fragmentation.
When crushed material is smaller than the discharge opening, it is automatically discharged from the crushing chamber bottom.
Each eccentric shaft revolution completes one "feed-crush-discharge" cycle for continuous crushing.
Deep cavity crushing, V-shaped chamber design, crushing ratio up to 6-8, reducing crushing stages and downstream equipment investment.
Optimized chamber design, large eccentric throw, production efficiency increased by 30%; deep cavity with no dead zones for stronger feeding capacity.
Wedge-type discharge opening adjustment for good product shape; shim adjustment is reliable and convenient with wide range for various gradations.
Modular design, fewer wear parts for easy daily maintenance; quick-access maintenance ports reduce downtime.
Moving jaw assembly uses high-quality steel castings, heavy-duty eccentric shaft, stable operation; toggle plate auto overload protection for worry-free safety.
Individual roller modules can be replaced independently without dismantling the entire screen structure.
15-30% energy savings per unit, over double for system; low noise, less dust, low operating cost, green and environmentally friendly.
The main battlefield for primary crushing of metal ores (iron/copper/gold/manganese) and non-metal ores, can form a complete crushing-beneficiation-grinding production line with magnetic separators and ball mills。
Cement raw materials, limestone, sandstone crushing. Multi-stage toothed liners ensure uniform particle size, output meets concrete mixing station gradation requirementsquirements。
Manganese ore, chromite and other high-hardness alloy ore crushing. High-strength alloy steel frame withstands continuous impact of Mohs hardness 7-8.
Waste construction debris and industrial slag recycling crushing, with optional dust and noise control devices to meet environmental compliance requirements around urban areas.
