High Volume. Hard Duty. Exact Cut
Designed for high-capacity screening in mining, quarrying, and aggregates, our Inclined Vibrating Screens combine robust performance with operational simplicity. Available in both single-shaft and dual-shaft eccentric drive configurations, these heavy-duty mechanisms deliver reliable, true circular motion—ensuring consistent material flow, rapid stratification, and sharp separations for both scalping and final sizing.
Built to endure demanding conditions, each screen features a reinforced frame and a simplified, maintenance-optimized drive system that extends service life and reduces downtime. The inclined design naturally increases throughput, while compatibility with various deck layouts and screening media allows flexible adaptation to different materials and process requirements.
Engineered for maximum uptime and service accessibility, our screens—whether in single or dual-shaft configuration—deliver dependable, on-spec production, shift after shift.

Frequently Asked Questions
-
A stationary inclined screen is a vibrating screen unit mounted on a fixed structure or foundation, designed for permanent installation in mining and quarrying operations. Operating at an angle of typically 18° to 25°, these screens use circular motion to stratify and separate materials by size.
Unlike their mobile or portable counterparts, stationary inclined screens are engineered for continuous, high-volume processing within integrated crushing and screening plants, offering robust construction and long-term reliability for large-scale operations.
-
Stationary inclined screens are versatile performers suitable for a wide range of applications across multiple industries. Key applications include:
Aggregate production: Sizing and classifying crushed stone, gravel, and sand into marketable fractions in quarries and gravel pits.
Mining operations: Heavy-duty screening, from coarse scalping to fine classification, of minerals and ores.
Recycling: Processing construction and demolition debris, as well as recycled asphalt and concrete.
Industrial minerals: Screening materials like slag and other industrial minerals to precise specifications.
-
A stationary inclined screen operates using a circular motion vibrator mechanism. The vibrating unit, often featuring modular vibrators flange-mounted to the side walls, generates a circular throw at every point on the screen deck. This circular motion, combined with the screen's inclined angle, causes material to move forward across the deck surface. As material travels, it stratifies—with finer particles moving downward through the bed of material and passing through the screen openings, while oversize material continues across the deck and discharges off the end.
-
While both serve sizing functions, stationary inclined and horizontal screens differ in design and optimal application:
Inclined Screens: Operate at a steeper angle (15-20°), using gravity assist and circular motion to move material. They require less energy and are well-suited for high-volume applications with larger screen openings and less stringent specifications.
Horizontal Screens: Feature a flat deck with an elliptical or linear stroke. They use higher g-forces to move material and excel in precision screening, fines recovery, and handling sticky or high-moisture materials where space height is limited.
-
The throughput and efficiency of a stationary inclined screen depend on several critical factors:
Screen size and deck configuration: Larger screen areas and multiple decks (2, 3, or 4-deck designs) increase capacity and separation flexibility.
Vibrator settings: Adjustable stroke length, rotation speed (RPM), and amplitude directly impact material travel rate and stratification efficiency.
Screen media type: The choice of screening media (wire mesh, polyurethane, rubber modular panels) affects open area and wear life.
Material characteristics: Feed gradation, bulk density, moisture content, and particle shape all influence screening performance.
Screen angle: Adjustable inclination allows operators to optimize material flow for specific applications.
-
Selecting the optimal stationary inclined screen requires matching equipment features to your operational needs:
Define your application requirements: Determine whether you need primary scalping with coarse feed gradation or precise final screening of finished fractions.
Calculate required capacity: Match your tonnage requirements to manufacturer capacity charts based on material density and desired cut points.
Determine deck configuration: Decide between 2, 3, or 4-deck designs based on how many product fractions you need to produce.
Evaluate material abrasiveness: For highly abrasive materials, look for durable features like weld-free side walls to accommodate fatigue stress and robust vibrator components.
Consider screening media flexibility: Choose screens that accommodate multiple media types (modular, tensioned, or self-supporting) to adapt to changing material conditions.
Assess maintenance accessibility: Look for designs that offer easy access to decks and vibrators, along with features like extra clearance between decks for maintenance crews.
