Dual motion shale shaker is a kind of solids control drilling mud processing equipment. Shale shaker is the 1st stage solids control equipment to pre-treat drilling mud from drilling rigs. GNZS594F-SHBF is a Single Deck Dual Motion Shale Shaker. The shale shaker can be equipment with top weir feeder, or with back weir feeder.

GNZS594F-SHBF is a Dual Motion Shale Shaker. The shale shaker can work as Linear motion or Gradual elliptical motion. The working principle of dual motion is as below.

1) There are two vibrator motors mounted on the shale shaker, one of the vibrator motor can be adjusted manually. If the eccentricity is set to the eccentricity ratio we need, the forward and reverse excitation force of this vibrator will not change; the other’s eccentricity cannot be adjusted manually. The eccentricity ratio of forward and reverse is informed to the supplier in advance. The excitation force of this vibrator during forward rotation is exactly the same with the first one while it is only half of the first one when reverse rotating.

Generally speaking, the linear track motion is the opposite rotation of two vibrator motors; the gradual track motion is the same direction rotation of two vibrator motors.

When switching the two motion tracks at drilling site, it is necessary to wait until the shale shaker is completely stationary before switching through the button of the electric control panel. Before delivery from manufacture’s factory, the electric control cabinets will be equipped with function of shifting between dual motion shale shaker control and linear motion shale shaker control. The shale shkaker that has been delivered can realize track switching by adjusting the eccentric position and rotation direction of a vibrator.

Besides dual motion shale shaker, GN Solids Control can make linear motion shale shaker, mud cleaner, desander, desilter, decanter centrifuge and other solids control equipment.
