We produce high quality products with the best materials! or over 36 years, Red Star has been a company dedicated to the engineering and manufacturing of screening media that are widely used in the mining and aggregates industry.
Quarry screening systems are the core link connecting rock extraction, stone processing and resource utilization, which directly impacts the operational benefits, environmental protection standards and sustainable development capabilities of quarry enterprises With the advancement of smart quarries and green mining initiatives, quarry screening technology will continue to iterate—driven by innovations such as intelligent particle size detection, energy-saving drive systems and automated process integration These technological upgrades will not only enhance screening precision and operational efficiency but also further reduce carbon emissions and resource waste, providing key support for the high-quality development of the quarrying industry
Quarry screening equipment is designed with multi-specification apertures, which accurately classify mined raw rocks (such as granite, limestone, basalt, etc.) into multiple grades based on particle size: large-sized aggregates (≥31.5mm), medium-sized aggregates (10-31.5mm), small-sized aggregates (5-10mm), and stone chips (≤5mm). This perfectly matches the process requirements of subsequent processing (such as secondary crushing, shaping, sand making, road construction material processing, etc.) and meets the differentiated needs of different customers for stone specifications (such as building foundation filling, road paving, concrete aggregates, etc.).
Precise screening and classification can significantly reduce ineffective processing links, avoid repeated crushing caused by unqualified stones entering subsequent processes, and greatly lower production time costs and energy consumption. For example, medium-sized aggregates meeting road paving standards can be directly transported to the finished product yard without re-crushing; stone chips that meet the requirements of sand-making raw materials can directly enter the sand making machine, skipping redundant processing steps and improving the overall production flow efficiency.
Specialized high-efficiency screening systems for quarries (such as linear vibrating screens, circular vibrating screens, drum screens, etc.) feature high throughput and low failure rates. They can be flexibly adapted to the production capacity needs of quarries, significantly increasing the daily stone processing volume, shortening the production cycle from mining to finished products, and helping quarries achieve large-scale production.
By pre-separating extra-large hard rocks, soil impurities, and metal debris from raw rocks through the screening system, core downstream equipment such as crushers, sand making machines, and grinding machines can be effectively protected. This avoids equipment jamming, excessive wear, and other problems caused by uneven materials or impurity mixing, reduces equipment maintenance frequency and repair costs, and extends the service life of the entire production line.
Precise screening avoids "one-size-fits-all" over-crushing, only performing targeted processing on unqualified stones, thus reducing energy consumption in ineffective crushing links. Meanwhile, the uniform particle size of screened stones can improve energy utilization efficiency in subsequent processing links, complying with the development concept of energy conservation, consumption reduction, low carbon, and environmental protection in green mine construction.
Selection depends on material hardness, moisture content, particle size, and impact force:
Wet or sticky materials → Polyurethane mesh (anti-clogging)
High abrasion materials → Manganese steel woven mesh or perforated plate
High-precision screening → Stainless steel woven mesh
Heavy impact materials → Steel-edge PU panels or rubber screen panels
Choosing the correct mesh improves output and reduces downtime.
Service life varies with material abrasiveness, vibration frequency, installation tension, and screen type:
Polyurethane mesh: 3–12 months
Manganese steel mesh: 1–6 months
Stainless steel mesh: 2–8 months
Rubber panels: 4–12 months
Proper tensioning and selecting the right aperture significantly extend lifespan.
Clogging occurs due to moisture, irregular particle shapes, or unsuitable aperture designs. Prevention methods:
Use self-cleaning screens (wave or harp type)
Switch to polyurethane anti-blinding mesh
Adjust vibration amplitude and screen angle
Pre-screen wet or muddy materials
Anti-clogging solutions greatly improve screening efficiency.
Key points during replacement include:
Ensuring consistent tension across the entire screen
Checking the screen frame for deformation
Matching hook types or fastening systems with your screen machine
Cleaning the deck to remove remaining material
Proper installation reduces breakage and improves screening accuracy.
Screening efficiency can be improved by:
Choosing the right aperture and mesh material
Adjusting vibration frequency and screen inclination
Maintaining uniform material feeding
Using multi-stage screening designs
Performing regular maintenance on screen decks and meshes
Efficiency improvements of 10–30% are commonly achievable.
