Application of polyurethane screen in screening of building sand and gravel
- The dilemma of traditional screens in sand and gravel screening
Insufficient wear resistance
Metal screens are easily worn due to the impact of sand and gravel, and need to be replaced frequently (such as 5-8 times a month in a sand and gravel plant), resulting in high maintenance costs and affecting production efficiency.
Wet sand is easy to clog
When screening high-water-content sand and gravel, the metal screen has a high clogging rate, the screening efficiency drops by 20%-30%, and the particle size uniformity is poor.
- The core advantages of polyurethane screens
Ultra-high wear resistance
Wire rope skeleton + polyurethane material, the wear resistance is 8-10 times that of metal screens, and the service life is extended to more than half a year.
Excellent anti-clogging performance
140° cone angle sieve hole design + high water permeability, wet sand screening efficiency increased by 35%, such as the coastal sand and gravel field case.
Precise screening control
The mold casting process ensures accurate aperture, and the customized sieve hole meets different engineering standards (such as 0-30mm sand and gravel classification is 5-10mm, 10-20mm, 20-30mm).
Shock absorption and noise reduction
Polyurethane elastic absorbs vibration, reduces noise by 5-20 decibels, and extends equipment life.
- Innovative application case: Turkey mine practice
Requirement: Accurately classify 0-30mm mixed sand and gravel into three grades (5-10mm, 10-20mm, 20-30mm).
Solution: Square swing screen + polyurethane anti-blocking screen.
Results:
Screening accuracy: 97.5% of coarse aggregates above 20mm.
Efficiency improvement: Screen replacement time is shortened from 2 hours to 15 minutes, and annual maintenance time is reduced by 500 hours.
Energy saving and consumption reduction: Unit power consumption is reduced from 1.2kW·h/ton to 0.78kW·h/ton, and the annual electricity bill for a single line is saved by 280,000 yuan.
Stable quality: Aggregate qualification rate exceeds 98%, and the standard deviation of concrete strength is reduced from 4.5MPa to 1.8MPa.
- Future Outlook and Industry Trends
With the improvement of quality requirements for construction sand and gravel and the promotion of environmental protection policies, polyurethane screens will further replace traditional equipment and help the industry achieve efficient and low-carbon production.
