How the Star Screen Revolutionizes Material Sorting

What is a Star Screen?

A star screen,  is a mechanical screening machine that uses rows of rotating star-shaped discs to separate materials by size.Unlike traditional vibrating screens, it operates smoothly without vibration, making it particularly effective for wet, sticky, or lightweight materials that often clog conventional equipment. It plays a vital role in waste management by providing reliable primary or secondary screening in waste sorting facilities.

Key Features

Qinglv's star screen is designed for performance and durability in demanding environments: 

Vibration-Free Operation – Reduces wear and prevents clogging, even with moist or adhesive waste.

Modular & Adjustable Design – Star disc modules can be easily added, removed, or spaced to meet specific sizing requirements.

Variable Speed Control – Operators can quickly adjust disc rotation speed to change the effective screening size without mechanical changes.

Easy Maintenance – Individual star discs can be replaced without dismantling the entire unit.

Compact & High-Capacity – Despite its small footprint, it can achieve throughput rates of up to 30 m³/h, especially efficient with damp waste streams.

Applications of Star Screens

Star screens are versatile and widely used across various waste streams:

MSW (Municipal Solid Waste) – Removal of organic fraction, plastics, and fines. 

C&D Waste – Separation of wood, plastics, and small aggregates from debris. 

Organics & Composting – Screening out contaminants and refining compost output.

Pre-Sorting for AI Systems – Preparing a more uniform feed for downstream AI waste sorting or AI garbage sorting units.

Benefits of Using Star Screens

Integrating a star screen into your waste screening equipment lineup delivers clear operational advantages:

Improved Sorting Quality – Clean separation increases purity of recovered materials.

Lower Downtime – Resistant to blockages and built for continuous operation.

Energy Efficiency – Smooth rotational movement consumes less power than vibratory systems.

Reduced Maintenance Costs – Durable construction and accessible components extend service life.

Enhanced System Flexibility – Can be tuned for different materials, seasons, or project requirements.

Our Commitment to Innovation

At Qinglv, we don’t just supply equipment – we engineer integrated solutions. Our star screen is part of a broader intelligent sorting ecosystem that includes AI sorting robots, optical sorters, and complete waste recycling lines. By focusing on reliability, adaptability, and efficiency, we help recycling plants and waste processors increase recovery rates, reduce costs, and support the transition toward a true circular economy.

Whether you’re upgrading an existing facility or planning a new waste sorting plant, Qinglv’s star screen offers a robust, high-performance screening solution designed to keep your operation running smoothly and profitably.
