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 12 m and 15 m (40 ft and 50 ft) of width, respectively. 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.
The Megatex XD is a reaction drive screener and must be suspended from existing framework or a Rotex supplied support stand. The suspension system consists of four hanger assemblies and isolates 95% of forces from adjacent structures.
Because the Megatex XD suspension system has low transmitted forces, the machine can be mounted directly to a structural steel framework.
Rotex supplied stand
Megatex XD Screeners can be floor mounted using a support stand designed for a specific model.
