Optional Feeder Types of Shale Shaker in Mud System

In drilling mud system, oilfield drilling shale shaker is a device that removes undesirable solids from mud. Drilling bit cuttings and pieces of formation that have brought into the wellbore (or called “drilling solids) and brought out to the surface by the drilling fluid. The fluid flows across a shale shaker before entering the mud tanks to be treated. Most drilling shale shakers install a vibrating motion to a weir or plastic mesh screen. This motion allows the drilling mud to pass through the screen and remove solid lager than the openings in the shaker screen. The shale shaker is the primary and the first stage drilling solid removal equipment in solid control system and usually combined with other solid control equipment.

Drilling Fluids Recycling Shale Shaker

Weir height is usually a very important information for the shale shaker for oil and gas drilling mud program. Explanation is the fact that the drilling fluids fall directly to shake shaker from the higher pipeline with no any enable from pump or a thing likely, so at least the total height of tank and shale shaker weir ought to no higher than the outlet of fluids in the drilling rig.

In case the total height of weir height and tank height exceed the height of rig outlet, that is the case we don’t would like to see, since in that case, the drilling fluid from the rig is not going to attain the shale shaker. So KOSUN Solids Control supplies customers from distinctive fields for Oil&Gas drilling, HDD, Piling.

More optional feeder types of drilling fluids shale shaker:

1. Weir feeder: traditional feeding type of oil&gas drilling solids handle shale shaker. Drilling fluids firstly enters into the box behind the shale shaker, when the fluids level is higher than the weir, it flows over weir and falls onto the shaker deck with screens. The function of weir feeding is to reduce the pressure and protect the shaker screens.

2. Box feeder in HDD or TBM projects, drilling fluid is not from the rigs, instead, it was conveyed by a pump from mud pit or probably places. So box feeder is possible here, it requires less space during transportation.

3. Hopper feeder: hopper feeding type is KOSUN designed especially for waste management high-G shakers. In this stage of treatment, the treated material is from augers, so hopper feeder is more practical at jobsite.

4. Besides the above most commonly options, KOSUN also has low weir feeding shaker available, LS703 with weir height 500mm.
