Nowadays, the most popularly used oilfield shale shaker are BEM(Balanced Elliptical Motion) and Linear Motion. In China, GN Solids Control is the first one who got the API Certificate for producing shale shaker and other drilling fluids recycling equipments for oilfield application.

When need shale shaker BEM or Linear Motion

Usually, shale shaker is used as the first stage drilling fluids recycling equipments in the Mud System, and the drilling fluids with cuttings flow into the shaker distribution box through rig elevated manifold.

  • Linear Motion – for fast conveyance and heavy loading

Linear motion shaker is especially effective while drilling top hole sectiong where heavy, high volume solids are usually encountered. In these intervals, shakers need to generate high G forces to effectively move dense solids across the screens.

  • BEM – for maximum retention time and drier cuttings

The BEM type shale shaker has gentler reduced G force, and the special vibration mode make the solids stay on the screen for longer time. This results in drier solids, improved drilling-fuid recovery, longer screen life and reduced operation costs.

BEM Shale Shaker Manufacturer

MI Swaco, a Schlumberger company, could offer the Mongoose PT daul motion shale shaker which could be adjust the vibration mode from linear motion to BEM “on the fly” by fliping the switch without suspending or shutting down the operation.
GN Solids Control, only foucs on International market and high level domestic market, could offer both the Linear motion and BEM shale shaker used in not only Oilfield, but also the HDD & CBM.  The simple structure design and top quality make GN get more and more praise from our customer.
Mongoose daul motion shale shaker by using an extra 0.6hp vibration motor to allow the shaker perform on an unparalleled level, GN’s BEM shaker is using 2 units motor with different power.

Comparing with BEM shaker, Linear motion is more acceptable due to the mature technical and large quantity oilfield application experiencies. GN Solids Control would be your reliable supplier for solids control equipments once you have any request aroused.

GN shale shaker

GN shale shaker

Shale shaker is one type major solids control equipment used in oilfield drilling, HDD or other drilling projects. Nowadays, the most advantaged shale shaker is the balanced elliptical shale shaker, while the most popular used is the linear motion shale shaker. What is the difference between the linear motion and balanced elliptical shale shaker.  Let’s talk something about it.

Shale shaker generation developing

As we known, the second generation shale shaker is Elliptical motion, the third generation is linear motion and the fourth generation is balanced elliptical motion. Many clients often regard the fourth generation as elliptical motion, however, that is an incorrect understading about it. Please refer the pictures below, you could find the difference of these two vibration mode:

Linear Motion

Linear Motion

Linear motion shale shaker often apply 2 vibrating motor with same power, but the vibrating direction is opposit horizontal. At the vertical direction, the vibrating force produced by 2 motors will reduplicate. Thus the vibrationg mode is a linear and forward direction.

While on a Balanced elliptical shale shaker, the 2 vibrating motors are different in power, that results an unbalanced force counteracting. So the vibration mode will be like that (shown in below picture.)

Balanced Elliptical Motion

The balanced elliptical shale shaker is a production from combination of commerce and science. GN  BEM shaker won the National technology progress awards.

By now, we have exported many sets BEM shale shaker to our customers, if you want learn more about shale shaker or need a quote, just feel free to contact with us.
