Star screens are essential for enhancing the efficiency and accuracy of sorting various materials, contributing to improved recycling rates and waste reduction.
What is a Disc Screen?
Disc screen is a type of industrial screening equipment designed to separate materials based on size. It consists of multiple rotating shafts equipped with star-shaped discs that create a screening surface. As materials pass over the screen, the material is scattered by the rotating star claws, and jumps and rolls forward. The material smaller than the star screen will fall along the gaps between the stars due to its own weight and the overturning force of the screen axis, while the material larger than the stellar screen will stay on the screen and then move forward to the next process flow.

High-Efficiency Disc Screen for Waste Recycling Centers
The disc screen makes the separation of the dry and wet fraction of municipal solid waste simpler, more effective, and economically advantageous. Municipal solid waste screening systems are capable of separating up to 100 T/H using just 15 kW of power.
In the case of municipal solid waste, screening is fundamental as it helps municipalities and private companies that use MSW shredders and grinders to simplify the recycling process as much as possible. This process applies to both the separation of the organic fraction from the municipal solid waste to be transformed into compost or biogas, and the separation of the light fraction for the production of RDF (Refuse-derived fuel). When the municipal solid waste is adequately separated by innovative screening solutions that guarantee the best results, both can be transformed into high-quality materials and put back on the market.
Key Features
Disc Screen are known for their reliability and efficiency.
- Star-Shaped Discs: Provide effective separation by allowing smaller particles to fall through gaps while larger particles are transported forward.
- Adjustable Speed: Enables precise control of screening speed to accommodate different material types and separation requirements.
- Modular Design: Allows for easy maintenance and customization of the screen to meet specific operational needs.
- Durable Construction: Built with high-quality materials to withstand heavy use and harsh environments.
- Low Maintenance: Designed for easy cleaning and minimal maintenance, reducing downtime and operational costs.
Characteristics of Disc Screen
Excellent material agitation and separation
Patented in-line discs provide accurate sizing of material, reducing product loss
Disc and shaft design reduces material wrap, increasing uptime
Small footprint，Low power consumption
Working Principle of Disc Screen
Operational Mechanism of Disc Screen
The screen surface of the disc sieve is composed of many parallel arranged roller shafts with sieve discs installed alternately on them. The rollers rotate through sprocket or gear transmission, and their rotation direction is the same as the direction of material flow. Due to the fact that the sieve shaft is arranged at different working angles, the material moves faster when running at higher working angles. When the material runs at a lower working angle, the speed is slower. Two materials running at different speeds start to move axially when they meet at a certain position on the screen surface, which evenly distributes the materials on the screen surface and achieves the goal of improving screening efficiency.
Applications of Disc Screen
In the case of municipal solid waste, screening is fundamental as it helps municipalities and private companies that use MSW shredders and grinders to simplify the recycling process as much as possible. This process applies to both the separation of the organic fraction from the municipal solid waste to be transformed into compost or biogas, and the separation of the light fraction for the production of RDF (Refuse-derived fuel). When the municipal solid waste is adequately separated by innovative screening solutions that guarantee the best results, both can be transformed into high-quality materials and put back on the market.
Common applications include:
- Municipal Solid Waste (MSW): Separating organic and inorganic materials to enhance recycling and composting processes.
- Construction and Demolition Waste: Sorting debris such as wood, metal, and aggregates for recycling and reuse.
- Biomass Processing: Screening biomass materials like wood chips and green waste for energy production and composting.
- Recycling Plants: Separating various recyclables such as plastics, paper, and metals based on size.
- Composting Operations: Removing contaminants and separating organic materials to produce high-quality compost.
Benefits of Using Disc Screen
Implementing star screens in material separation processes offers numerous benefits:
- Increased Efficiency: Enhances the speed and accuracy of material separation, reducing manual sorting requirements.
- Improved Material Recovery: Increases the recovery rate of valuable materials, supporting recycling efforts.
- Cost Savings: Reduces labor costs and operational expenses through automated and efficient sorting.
- Enhanced Product Quality: Produces cleaner, higher-quality separated materials, improving the value of recycled products.
- Environmental Impact: Supports sustainable waste management practices by increasing recycling rates and reducing landfill usage.
