Corrugated-shaped shale shaker screen advantage

Shale shaker screen is the essential part in filter solids from liquid, and it is disposable part in various drilling that need to replace all the time.

Because of the drilling fluid that contains corrosion, abrasiveness and heat,it needed to filter solid particles for long period time.  Generally speaking, the material of shaker screens are all constructed in stainless steel and the wire which disposed by heat treatment technology. The auxiliary support structure is made of steel plate, galvanized sheet, and others combined materials.

With the continuous development of science and technology, in order to enhancing the filter effect of screen, the corrugated- shape screen was developed. It is improved and upgraded from flat type screen, started to be implied in the mid-1990s.


Corrugated- shape screen synthesize the advantage of common crochet screen and orifice plate adhesion screen, but it is based on the structure size of shale shaker will not be changed, and the frequency and exciting force of vibration exciter will not be changed as well.


The advantage of the corrugated- shape shale shaker screen is that it breaks the limitation of traditional plate screen, because of the unique wave pattern of screen, it is not only has the service life increase and as well as filter effect of orifice plate adhesion screen by increase the filter area of screen more.


When the drilling fluid flow to the screen surface, the solid phase will flow to valley bottom of corrugation, vertical surface can provide more filter area for drilling fluid, so compared with flat surface screen, the wave screen has through capacity. The thruput is larger 30%~40% than orifice plate adhesion screen and other flat surface screens. And diamond screen increases the residence time of drilling fluid on the screen surface, has a better sieving effect.
