MEGATEX Grain Cleaner

The MEGATEX Screener provides a high capacity solution for effectively screening high volumes of materials that would typically overwhelm a single conventional screener. Providing 100 to 350 square feet (9.3 to 32.5m2) of screen surface in a compact 10’ by 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 as well as significant savings in regards to installation, operations, and floor-space.

MEGATEX Screeners vs. Conventional Screeners

In order to achieve high production and load-out rates, screen areas of 350 square feet are often required. In order to accommodate these screen areas, a conventional screener would need a screen deck measuring 12' x 30'. Not only would such a machine consume excessive amounts of floor space, but its use would also result in such deep mats of material on the screen surface that efficient screening would be impossible.
In contrast, the MEGATEX Screener uses a unique design to evenly split and distribute the incoming flow of material across multiple 5' x 7' screen decks arranged in a stacked configuration. One MEGATEX Screener is equivalent to 10 individual ROTEX Screeners.

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.

Installation Options

The full line of MEGATEX Screeners are available for a variety of general purpose and finer process screening applications.

  • 100 Series Screeners with 120 or 180 square feet of screen surface area.
  • 200 Series Screeners with 210 or 280 square feet of screen surface area.
  • 300 Series Screeners with 350 square feet of screen surface area.

Product Specifications

Title: 
High Volume Screening
Description: 
Industrial Minerals to 200 TPH Grain/Ag products to 1000 TPH Dry Chemicals from 60-100 TPH Particle Board Furnish to 20 TPH Plastic Pellets from 60-150 TPH
Title: 
Compact Design
Description: 
With a footprint of 10' x 10' x 12' or smaller, MEGATEX screeners occupy far less floor space than the multiple conventional units required to obtain the same levels of production. This results in lower installation costs and reduced maintenance expense.
Title: 
Easy Screen Access
Description: 
Full-width, hinged doors provide easy access to all levels and screen decks. Screen decks are conveniently sized for easy removal and handling by two workers.
Title: 
Vibration Isolation
Description: 
Cable suspension system isolates as much as 95% of the forces of the moving assembly eliminating transmission to adjacent structures. Less structural support is required, resulting in lower installation costs.
Title: 
Quiet Operation
Description: 
Low-frequency, gyratory screening action produces very low noise levels-far lower than those produced by vibratory screeners and well within the comfort range.
Title: 
Dual Service Option
Description: 
A two-point feed system allows each bank of the machine to be used for separate service.
Title: 
Patented Feed Splitter
Description: 
The patented feed arrangement evenly splits the material to each of the screen levels, ensuring uniform flow to each deck for maximum screen utilization and screening accuracy.
Title: 
Single Point Distribution Deck
Description: 
The distribution deck is fed at a single point, eliminating the expense of multiple feeders and related components. The long-stroke, gyratory motion spreads feed material evenly across the distribution deck.
Title: 
Discharge Doors
Description: 
The discharge doors serve to combine the screened fractions and discharge them. Quick-release door clamps provide easy access to all screen decks for inspections, maintenance and screen changeouts.
Title: 
Low Maintenance, Two-Bearing Drive
Description: 
The long-stroke, gyratory motion is supplied by a rugged, two-bearing, reaction-style drive. Power is supplied by a 10 or 15 horsepower motor, for economical operation.
