Mining screens classify materials by particle size, ensuring that only suitable materials proceed to the next stage be it crushing, refining, or transport. Efficient screening enhances throughput, reduces waste, and minimizes downtime from blockages or equipment issues(Vibrating, 2024).
Below are some of them:
Use Larger Chisels: Larger chisels increase vibration force and stress, helping break particle bonds and improving material stratification, leading to higher screening efficiency.
Control Material Load: Keeping the material load at around 80% of screen capacity and using screens with a length-to-width ratio over 2:1 enhances efficiency by ensuring sufficient screening area.
Optimize Inclination Angle: Adjusting the screen’s tilt (around 15°) helps control material flow speed—keeping it below 0.6 m/s boosts screening accuracy without sacrificing too much capacity.
Use Variable Inclination (Broken Line Screens): Screens with segmented inclination angles adjust material flow speeds across sections, ensuring consistent material spread and improving screening performance.
Adopt Multi-Layer Screens: Multi-layer setups with gradually larger apertures and decreasing slopes improve separation by preventing clogging and allowing better stratification of fine and medium particles(5 Ways to Improve Screening Efficiency – SBM Industrial Technology Group, n.d.).
What if the secret to a more profitable mining operation is simply in a better shake?
