How To Reduce the Cost of Wire Screens in Mining and Quarrying Industries

Replacing wire screens in mines and quarries can be a major expense. Most people think you just have to keep buying new parts as they wear out, but you can actually make them last much longer with some basic maintenance. Here are six straightforward ways to cut down those costs.

Tip 1: Add a Buffer Pad to the Screen Inlet

First, try adding a buffer pad where the material enters the screen. Most wire screens get damaged by the impact of rocks hitting them rather than just wearing down over time. If you put a piece of rubber or an old conveyor belt at the inlet, the material hits that layer first before sliding onto the screen. This is a nearly free solution that helps the screen last much longer.

Tip 2: Regularly Rotate the Screen

You should also rotate your screens regularly. The end where the material comes in always wears out faster than the exit. If you flip the screen every two weeks, the wear stays even across the whole surface, which extends its overall life.

Tip 3: Don't Rely on Feel for Tension

Don't just tighten the screens by feel. Everyone has a different idea of what feels tight, and inconsistent tension leads to the wire screen breaking or deforming. Using a torque wrench ensures every hook has the same amount of pressure. It is a cheap tool that prevents a lot of unnecessary damage.

Tip 4: Clean Clogged Screen Holes Promptly

Make sure to clean out clogged holes right away. When material gets stuck, it creates extra friction and buildup that wears the screen down faster. A quick spray with a high-pressure water or air gun after you shut down for the day makes a big difference, especially with wet materials. Spending ten minutes cleaning the screen every day can save a lot of money in the long run.

Tip 5: Choose the Right Material, Don't Go for Cheap Options

Pick the right material instead of just buying the cheapest option. Cheap screens might seem like a deal, but they often wear out too quickly. If you are working with abrasive materials, using manganese or spring steel is better. They cost more upfront, but they last so much longer that the actual cost for every ton you process ends up being lower.

Tip 6: Protect Screens from Rust

Finally, protect your screens from rust. If your equipment is outside, rust will weaken the wire and make it snap sooner. When the machine is not running, cover the metal wire screen with a waterproof tarp or spray it with some rust-preventive oil. Also, try to keep it from touching regular carbon steel to prevent corrosion.

Lowering your screen costs is not as hard as it seems if you stick to the basics. By using buffers, rotating the screens, using proper tools for tension, cleaning them daily, choosing quality materials, and preventing rust, those expenses become much more manageable.
