MEGATEX Grain Cleaner

Wide-Screen Design

When handling higher capacities, the depth of the material passing over the screen on conventional screeners increases. Increased bed depth diminishes the screener’s ability to stratify material, which is essential to effective screening. Expansion of the total screen area is key to increased screener capacity — but only if the area is increased properly. All screen area is not equally productive. Increased screen width expands capacity more effectively than increased screen length. MEGATEX grain screeners handle increased capacity and maintain screening accuracy by utilizing screen surfaces that are wider rather than longer. Using a two-bank, multilevel screen deck arrangement, MEGATEX grain screeners present 40 feet and 50 feet (12 meters and 15 meters) of width, respectively. This width serves to keep bed depths low, so screening accuracy and efficiency are maintained at high capacities.

Long-Stroke, Gyratory Motion

The force level created by the long-stroke (up to 7.5 centimeter), low-frequency drive serves two important functions. First, the motion effectively spreads the material across the full width of the distribution panel. This achieves proportional feeding to each of the screen levels inside the machine and eliminates the need for multiple process feed points. Second, the long stroke and low frequency produce effective ball-mesh cleaning to control blinding, providing long-term, uninterrupted operation. Screening units employing shorter strokes or higher frequency drives cannot match these two functions of the MEGATEX high capacity grain cleaner. Thus their screening effectiveness is poor, resulting in product loss or poor product quality.
