A portable sloped screener, also known as a portable inclined screener, is a type of screening equipment used to separate and classify bulk materials based on particle size. It is designed with an inclined deck that slopes at an angle, allowing for efficient material separation and gravity-assisted conveying. 

Portable Sloped Screener Features

Portability: The key feature of a portable sloped screener is its portability. These screeners are typically mounted on wheels or skids, allowing for easy transport between different job sites or locations within a facility. They are often used in temporary or mobile screening applications where stationary equipment is not practical.

Inclined Deck: The deck of a portable sloped screener is inclined at an angle, typically ranging from 10 to 25 degrees. This inclined design allows for gravity-assisted material conveyance and improves the screening efficiency by ensuring that the material moves quickly and freely across the screen surface.

Vibration Mechanism: Some portable sloped screeners may incorporate a vibration mechanism to enhance the screening process further. This vibration can help loosen and separate sticky or agglomerated materials, improving screening efficiency and throughput.

Adjustable Angle: Portable sloped screeners often feature adjustable deck angles to accommodate different material characteristics and screening requirements. Operators can easily adjust the angle of inclination to optimize the screening performance for specific applications.

Versatility: Portable sloped screeners are versatile and can be used for a wide range of screening applications, including aggregates, topsoil, compost, mulch, sand, gravel, and more. They are commonly used in construction, landscaping, recycling, mining, and agricultural industries.

Multiple Deck Configurations: Some portable sloped screeners may offer multiple deck configurations, allowing for multi-stage screening and classification of materials into different size fractions. This helps improve the quality and uniformity of the screened product.

Efficient Material Handling: The inclined deck design of portable sloped screeners promotes efficient material handling and screening. The sloped surface helps prevent material buildup and blinding of the screen openings, ensuring continuous operation and high screening efficiency.

Compact Design: Portable sloped screeners are designed to be compact and space-saving, making them suitable for use in confined spaces or on job sites with limited space availability. Despite their compact size, they offer high screening capacity and performance.

Portable Sloped Screener Working Principle

Sloped Deck Design: The portable sloped screener features a deck or surface that is inclined at an angle to the horizontal plane. This sloped design allows gravity to assist in the movement of the material across the screen surface.

Vibration Mechanism: In addition to the sloped deck, the portable screener is equipped with a vibration mechanism. This typically consists of an eccentric shaft with unbalanced weights or flywheels attached to it. When the motor rotates the shaft, it generates vibration that is transferred to the screen surface.

Material Feed: Bulk materials are fed onto the top of the inclined screen deck using a conveyor belt, chute, or other feeding mechanism. As the material flows down the sloped deck, the combination of gravity and vibration causes it to spread out evenly across the screen surface.

Screening Process: As the material moves down the inclined deck, smaller particles pass through the openings in the screen surface, while larger particles are retained on the screen. This separation process effectively classifies the material into different size fractions.

Adjustability: The angle of inclination of the screen deck and the amplitude and frequency of vibration can often be adjusted to optimize the screening process for different types of materials and desired screening efficiency.

Multiple Deck Configurations: Some portable sloped screeners may feature multiple screen decks stacked vertically. Each deck may have different screen openings or mesh sizes to facilitate the separation of materials into multiple size fractions simultaneously.

Portability: As the name suggests, portable sloped screeners are designed for easy transport and mobility. They are often mounted on a wheeled chassis or skid base, allowing them to be easily moved from one location to another as needed.

Versatility: Portable sloped screeners are versatile and can be used for a wide range of applications, including screening of aggregates, topsoil, compost, mulch, and other bulk materials. They are commonly used in construction, landscaping, recycling, and mining operations.
