The Development Status and Level of Foreign Shale Shaker

2013-08-27

Characteristics of modern shale shaker are high excited force, balanced motion, fine mesh, multilayer screen and large processing capacity, it develops towards energy-saving and environmental friendly, its low energy consumption and low noise mainly reflected in the following aspects:

a. Develops more than 200 mesh ultra-fine, high strength, large handling area screens;

b. Diversified, modular and instant adjustable vibration screen box;

c. To minimize maintenance or maintenance free, hydraulic or pneumatic when replacing or clamping screen or adjust  screen angle and other components;

d. Develop a set of desander, desilter in one multi-functional shale shaker;

e. Beginning to support the use with the drilling fluid automated data collection, detection and processing system. 

Currently, foreign shale shakers are mostly American made which have a high level in production and processing, package selection, use and maintenance, etc. Their good comprehensive mechanical properties makes them a leading position in shale shaker application. Foreign shale shakers are mainly produced by DERRICK , BRANDT , SWACO and other companies. 

In recent years many improved researches have been made in overseas, characterized mainly as: 

a. Adopt screen box seat with adjustable screen slope, segmented and multi-angle installation of  screens, increase the efficiency and handling capacity of screens as far as possible;

b. Using mechanical pressing method to produce multilayer stacked screens, especially 3D wave shape screen technology which can make screen area increased 50%-125% than flat screens; 

c. Adopt ultra fine screens more than 200 mesh; 

d. Using explosion-proof type vibration motor as vibration exciter, sealed bearing lubrication system, inertial force excitation is 1. 5- 1. 7 times than  conventional vibrator.
