A reclaimer is a machine which removes the drill cuttings and maintains the proper viscosity of the fluid. It is used for cleaning and recycling used drilling fluid. As drilling fluid is used, it travels to the reclaimer via the rig’s mud system. The reclaimer recycles the used fluid and reintroduces it into the mud mixing system.
Trenchlesspedia Explains Reclaimer
All horizontal directional drilling operations require a mud system to supply the rig with drilling fluid (mud or slurry). Having a reclaimer as part of that system, that works to recycle mud so it may be used more than once, is financially desirable due to the cost of disposing of the used drilling fluid. The reclaimer circulates the used mud back into the mixing system to increase the volume of the unused mud which helps to provide a sufficient supply of drilling fluid for the drilling operation.
