MEGATEX™ SCREENERS - Northland Engineering Sales, Inc.

MEGATEX™ SCREENERS are the high capacity solution for effectively screening high volumes of materials that would overwhelm a single conventional screener. MEGATEX Screeners provide efficient, accurate separations at production rates greater than other large capacity screening options. Providing 100 to 350 ft2 (9.3 to 32.5 m2) of screen surface in a compact 10' x 10' x 12' (3m x 3m x 3.7m) machine, MEGATEX Screeners can do the job of multiple conventional screeners, resulting in lower initial capital expense, plus significant installation, operating and floor-space savings.

MEGATEX VS. CONVENTIONAL SCREENERS
It is not uncommon for high production and load-out rates to require screen areas of 350 square feet. To handle this on a conventional screener would mean a screen deck measuring 12' x 30'!Not only would such a machine consume excessive floor space, its use would result in such deep mats of material on the screen surface that efficient screening would be impossible. The MEGATEX uses a unique design to evenly split and distribute the incoming flow of material to multiple 5' x 7' screen decks arranged in a stacked configuration. It's like having a bank of 10 ROTEX Screenersin one machine!

HOW IT WORKS

WIDE SCREEN DESIGN When handling higher capacities, the depth of the material passing over the screen 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 screeners handle increased capacity and maintain screening accuracy by utilizing screen surfaces that are wider rather than longer. Using a two-bank, multi-level screen deck arrangement, MEGATEX screeners present 16' to 50' of width to the feed. 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 3"), 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 MEGATEX screeners. Thus their screening effectiveness is poor, resulting in product loss or poor product quality.
