GN Solids Control has served oil gas industry for more than 13 years. We mainly produce solids control equipment for drilling mud treatment and also the drill cutting process. Last month we just shipping one cutting dryer and screw conveyor to Africa to oilfield drilling field.

The drilling mud carry lots solids from well, after separation by the shale shaker. The clean mud will return back to mud system for drilling again. But the discharged drill cutting from shaker still very wet, which involved lots of drilling mud. As we all know drilling mud has lots high pollution chemical material, it can continuously influence the soil for many years, and drilling mud is very expensive. So we need to recycle these drilling mud as much as possible to reduce the pollution to environment and also save the cost of mud.

vertical cutting dryer

In this African project , screw conveyor can directly catch the discharged solids from shaker and transfer it into vertical cutting dryer. Inside dryer, there is cone shape basket with opening hole. Motor will drive the basket and generate separation force. Although solids and liquid both bear the separation force, but solids can not go through the opening hole, because the diameter is higher than the basket hole. The liquid mud will go through the basket and be collected. The primary is similar with dry function of washer. Dewatered solids will down to bottom of dryer and transport away for further process.

screw conveyor

As usually, vertical cutting dryer is used for oil base drilling mud. Sometime client use it for water base mud, the solids may block the opening. So we do not suggest client use it for water base mud. After treatment , 95% percent of drill mud can be recovery. However the recovered liquid need to be further treated by decanter centrifuge to remove out bigger size particle, and then turn back to solids control system.

GN not only provide equipment, but also good at customize system, if you have the similar project, welcome to contact us.
