Linear Motion Round Drilling Mud Desander Desilter Remove Solids

Round Drilling Mud Desilter to Remove Silt-sized 15 to 45 Microns Solids from Drilling Fluids

Mud desilters are designed to remove solids 15 to 45 microns from drilling fluids. AIPU round desilters are simple to operate and easy to maintain. 

Our process is achieved by a combination of hydrocyclones mounted over a shale shaker to operate as a single unit. The hydrocyclones make the primary separation with underflow directed onto the shaker vibrating screen.

Cones on mud desilters are all high-quality polyurethane 4" cones. Such cones are durable and anti-corrosive, oil-resistant, high temperature-resistant. They are very suitable for the drilling fluids process. For some clients, they prefer flexible capacity adjustment during operation so we'll install ball valves on the cones inlet line. 

Mud desilter APCN240 configuration

Mud desilter APCN240 is equipment consisting of the shale shaker Hunter-MG3, desilter cone 4", electric control panel and pipelines. We call it two in one, too. For oil drilling mud process, desander cone is sized 8-12''. The desilter cone is 4'' or 5''. Different size cones hold different treating capacity. When we confirm the configuration or design of mud cleaner, we should consider the general flow rate of all cones. For example, 4" cone capacity is about 20m³/h and we request a 240m³/h flow rate we need to configure 12 cones at least. To consider some heavy mud and large solids content we suggest 125% of rated capacity.

Drilling mud is transferred to cones by a centrifugal pump from the shaker tank. Desander cone and desilter cone are fed by different pumps. This will provide better results. Under pump pressure, the fluids will run into cones and flow with centrifugal force. Then the heavy particles will deposit down and pushed out of cone drop in Apex.

After the mud cleaner processing, the solids larger than 15 microns will be separated out of drilling fluids. The drilling mud with solids sprays out of cones drop down to the bottom screen panel. Under vibration and filtration, the solids will be drier and save many fluids for a good drilling. The cleaned mud is transferred to centrifuge.

Our mud cleaners are equally effective for both weighted and unweighted drilling fluids and effectively lower both drilling fluid expenses and disposal costs.

Some clients don't know the difference between desander and desilter. Actually, it's very easy to identify them. Bigger cone separate larger particles, smaller ones separate the finer particles. And fluids will be separated by desilter after processed by desander. 

Besides mud conditioner, the separated desander and desilter is another option for users. Please refer to information on desander and desilter for more reference. The bottom shaker under the mud cleaner cone is used to dry fluids out of the cone. So, the mesh size is rather high and the capacity is enough for discharge from cone but not the same as the previous shaker
