With the development of drilling technology, drilling depth is deeper and deeper, and mud requirements are more and more strict. Some complex geological conditions under the ordinary mud shaker can no longer meet the requirements of use. Moreover, the performance of the ordinary drilling vibrating screen is not very stable, and the effect of drilling vibrating screen treatment can not be adapted according to the drilling geology, often there will be some run-slurry or “horseshoe effect”. The appearance of the translational elliptical vibrating screen has solved these problems.
The translational elliptical vibrating screen USES 2 vibration motors of different sizes and keeps them on a datum level. Due to the different steering and excitation force of the two motors, the motion trajectory is elliptical. And the movement track of the whole sieve box of the translational elliptical vibrating screen is the same. The ellipse of the translational ellipse vibrating screen is different from the ordinary ellipse, the ellipse track and the screen have a certain Angle, so the “horseshoe effect” is avoided.
Advantages of translational elliptical vibrating screen:
- Treatment capacity is increased by 25%-30% compared with linear vibrating screen;
- Can adapt to a variety of geological conditions drilling mud recovery and purification;
- The excitation force can be adjusted;
- Linear vibrating screen has the advantages of translational elliptical vibrating screen have.
