The ViST screen shale shaker is a vacuum screen shale shaker utilizing vacuum power. GN Solids Control specially designed it to treat drilling mud in oil and gas drilling. It is work together to recycle the drilling fluids and reduce the drilling waste.
GN Solids Control started to developing the Vacuum Screen Technology since 2017 and owned many pending patent design on it. With the feedback from different jobsites, GN Solids Control keeps updrading its design to make it mode it more stable, less maitenance, and more user friendly. Through the years’ running, GN Solids Control Vacuum Screen Technology proved to be very efficient for recycling drilling fluids.
Based on GN Solids Control standard shale shaker, there is a catch pan installed under the discharge side of the shaker deck. There is a suction pipe with a rubber hose connected to the bottom of the catch pan for collecting the recycled drilling mud. As the sucktion pipe and rubber hose to the catch pan is short in length, GN Solids Control offers extension suction pipe to connecting the shale shaker to the vacuum unit. After that, there are discharge hose from vacuum unit to mud tanks.
And GN Solids Control screen vacuum unit is driven by air, the will be air hose from air compressor or other air suppliers, and feed air for the vacuum screen unit. The compressed air from air compressor or the rig air supply is required to create suction on the last screen surface, pulling additional fluid off the cuttings. It can reduce the liquid on the cuttings by 30-50%.
There must be a set of catch pan with its suction pipe, suction rubber hose and extension rubber hose for connecting to the vacuum unit. If the vacuum screen unit is connecting to 2 shakers or 3 shakers, there must be 2 packages or 3 packages of catch pan with its hoses. One vacuum screen unit only need a rubber hose with its extend discharge hose to mud tanks. And with an air hose to the air compressor or to the rig air supplier.
