APPLY's surge tanks are used to feed dry bulk materials as barite, limestone and bentonite into mud hoppers when mixing liquid drilling mud.
The advantages of APPLY's pressure vessel are its custom design and certification to fit the rig’s bulk piping configuration and available location in the sack room, an inward hinged manhole which is minimizing waste of dust to the environment when inspecting the tank.
Canvas mats instead of nozzles aerate the bulk material and avoid bridges to build inside the tank. The cell feeder with speed controlled electric motor assures an accurate dosage of bulk material.
