    Laboratory Metal Sieves

    Bohes metal lab sieves offer the following benefits:

    Long Screen Life:

    The screen cloth is held in the frame very tightly by a special process. This design enables clean screening, less screen wear and longer screen life.

    No Clogging of Screen:

    As the screen vibrates in multiplane hence the holes of the screen remain clear. Additional and blinding system is provided for difficult to screen and wet materials.

    Compact Design:

    This screen occupies less than half the spaces as occupied by any other screen of same capacity. Useful in wet screening The screen works on solid-liquid separation efficiently.

    Minumum blinding of screens:

    Due to vibrations in the vertical plane, blinding of screen is minimized. However, for certain materials which have inherent blinding, sticking property and special accessories can be used to eliminate this problem.

    Vibration free operation: 

    There are no vibrations at the screen base. Even no flooring is needed. You can mount it on Bins, upper floors, planks or wherever it is most suited.

    Low on power and maintainence / High on efficiency: 

    The design enables to utilize the vibratory force generated by the motor to the optimum and very few moving parts reduce the maintenance to minimum.
