screening machines

The Megatex Grain Cleaner provides a high capacity solution for effectively screening high volumes of agriculture materials that would typically overwhelm a single conventional screener. Providing 9.3 to 32.5m2 of screen surface in a compact 3m x 3m x 3.6m machine.

Megatex Grain Cleaner 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.


How High Volume Grain Cleaner Works How it Works


Gyratory Motion 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 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 40cm to 127cm 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 Reciprocating Motion The force level created by the long-stroke (up to 7.5cm), 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.

Grain cleaner Specifications Specifications


High Volume Screening Industrial Minerals to 181 TPH Grain/Ag products to 907 TPH Dry Chemicals from 54-90 TPH Particle Board Furnish to 18 TPH Plastic Pellets from 48-136 TPH

Vibration Isolation 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.

Pantented Feed Splitter The patented feed arrangement evenly splits the material to each of the screen levels, ensuring uniform flow to each deck for maximum screen utilisation and screening accuracy.

Low Maintenance, Two-Bearing Drive The long-stroke, gyratory reciprocating motion is supplied by a rugged, two-bearing, reaction-style drive. Power is supplied by a 10 or 15 horsepower motor, for economical operation.

Compact Design With a footprint of 3m x 3m x 3.6m 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.

Quiet Operation Low-frequency, gyratory screening action produces very low noise levels-far lower than those produced by vibratory screeners and well within the comfort range.

Single Point Distribution Deck 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.

Compact Design 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.

Easy Screen Access 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.

Dual Service Option A two-point feed system allows each bank of the machine to be used for separate service.

Discharge Doors Quick-release door clamps provide easy access to all screen decks for inspections, maintenance and screen changes. The discharge doors serve to combine the screened fractions and discharge them.
