Screen blinding occurs when some or all of the screen's open area is blocked by material. This may be caused by a too-high feedrate that dumps material onto the screen faster than the screen can operate. Or it might be caused by poor screen selection — for example, choosing a screen with too heavy a wire diameter. Or it might be caused by

The formulae do not indicate whether the suggested perforation is possible, they are to be used solely for calculation of the open area. The pitch dimension must in general be greater than minimum the hole size dimension + thickness of the material.
200 square - Used mostly in scalping applications, the smaller panel size combined with large apertures results in improved open area. The panels are normally thicker to allow for heavy duty applications. It has to be used in conjunction with our specially designed support frame which will fit most vibrating screens.
tend to pass through the screen and reduce blinding. Profile Wire screens are originally produced as cylinders or flat panels. Both methods of manufacturing offer their own features and benefits. Selection of the Profile Wire (size and shape) of is based on open area requirements, blinding considerations and wear life factors.
