LS703 Series Shale shaker

Shale shaker (linear motion shaker) is designed for mud cleaning from rock cuttings in the process of drilling the oil, gas and other wells, effectively removes slime from mud. Shale shaker is used as a screen for cleaning the mud, going out of well, and it can also be used in sumpless drilling system to keep the drill mud while working with desander and desilter. Degree of purification is up to 75 microns. The vibration motion is linear, which is more effective than a circular or elliptical motion.

Drilling Shale Shaker Features & Benefits:

  1. G-forces linear motion up to 7.4 G (adjustable depending on the situation)
  2. Hi-speed conveyance of cuttings
  3. Higher processing capacity
  4. Able to process heavier solids loads
  5. Enhances cuttings processing volume
  6. AWD device is adjustable from -1°~5°
  7. Single side shale shaker screens tension system to easily change the screens
  8. Shale shaker feeder can be weir feeder or box feeder


Structure of Shaker Deck:

KOSUN patented shale shakers is the equipment with welded structure. Vibration motor & screen plate base are installed into screen basket with special parts. Screen basket is fixed on the adjustment beam. At each of the four vertexes of the screen basket put a vibration damping spring, which can prevent the adjoining parts and devices from being affected by the vibration. There are several shale shaker screen panels on screen basket, and they are fixed and adjusted by snap-on screw bolts and hooking tensioners so that the combined effect of horizontal and vertical supporting bars can provide enough strength for screens basket

AWD angle adjustment system:

KOSUN patented AWD angle adjustment system can raise or lower the end of screen basket while the machine is working. This part includes two vertical column assemblies that are connected on the upper beam assembly and are attached to the shaker base.


The mud returned from the well or cuttings to be treated will flow into the shale shaker via the feeder. The feeders can be categorized into weir type, box type and bucket type. The weir type and box type feeders are mainly used to buffer the flow rate of drilling fluids and evenly distribute the fluids onto the shale shaker screen to reduce the impact of drilling fluids on the screen, extend the service life of screen and improve the treatment effect. Besides, the weir type feeder can also short-circuit the machine if necessary. The bucket type feeder is mainly used with the dryer shaker to collect and distribute cuttings.
