What Is Stratification and Why Does It Matter in Screening?

In mining and aggregate operations, efficiency starts with what happens on the screen surface. One of the most important, yet often overlooked, factors is stratification.

Stratification refers to the natural layering of material during the screening process. As material moves across the screen, finer particles work their way down toward the screen openings, while larger particles stay on top. This separation is essential for achieving accurate sizing and optimal throughput.

When stratification is limited, performance suffers. Fine material struggles to reach the openings, leading to increased carryover, reduced efficiency, and unnecessary recirculation. Over time, this can impact production targets and increase operational costs.

So how can operations improve stratification?

It starts with the right screen media. Solutions like MAJOR’s FLEX-MAT help create the conditions needed for proper material layering. By increasing vibration at the wire level and reducing blinding, more material is exposed to the screen surface. This allows fines to pass through more easily, improving separation and overall efficiency.

The result is a more effective screening process with less downtime, better product quality, and improved productivity.

Why Throughput Matters in Screening Operations

In mining and aggregate operations, throughput is one of the most important factors driving overall performance. The more material you can effectively process, the more productive and efficient your operation becomes.

Throughput refers to the amount of material that passes through the screening process over a given period. When throughput is optimized, operations can meet production targets more consistently while reducing bottlenecks and inefficiencies.

However, not all screen media delivers the same results.

A key factor influencing throughput is open area. Traditional polyurethane modular panels often limit the amount of material that can pass through due to reduced open space. This can slow down material flow, increase carryover, and ultimately impact overall efficiency.

By comparison, solutions like FLEX-MAT modular panels are designed with significantly greater open area. This allows more material to reach the screen openings, improving flow, reducing carryover, and enhancing separation efficiency.

The result is a screening process that handles more material, more effectively, with fewer performance limitations.
