As one of the important equipment for solid/liquid separation system, the drilling mud cleaner, also called desander and desilter assembly, mainly consists of three parts including desander, desilter and the underflow screen. It can achieve separation of two stage with the hydrocyclones mounted over the shale shaker. Compared with the independent desander and desilter, the product has much higher working efficiency. Same as the shale shaker in function, the equipment is designed rationally with compact structure, small volume and powerful performance.

The drilling mud cleaner is the cost-effective second class and third class solids control equipment in oil & gas well drilling fluids processing system as well as in HDD mud recycling system. It can process both weighted and unweighted drilling fluids system by separating and drying solids with the necessary fluids left for further treatment. After the processing via hydrocyclones of desander and desilter, the treated fluids flows onto the vibrating screen of shaker by underflow. If the product is used correctly, both the cost of drilling fluids and disposal can be reduced largely.

A mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone ( desander and/or desilter ) to separate particles and the underflow passes to the fine screen mesh where particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud system. It is usually located in a mud tank in the same location with the desilter.
 

The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite-size particles to pass through the screen returning and recovering the cleaned mud.

The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids between 74-105μm can be removed by the mud cleaner before the viscosity builds up. Mud cleaner can effectively control weighted drilling fluids solid content. It can also prevent sticking caused by differential pressure.

KOSUN Mud Cleaner can dry solids so it can be matched with our own advanced shale shaker. Meanwhile, the wedged type shaker screen allows people to change fast screen. The hydrocyclone of the desander and desilter is made of 100% PU and its number is set according to the needs of customers. With the hydrocyclone for desilter of clamp type and stainless steel ball valve available, the product can be maintained easily. Furthermore, the vibrating motor is compliant with ATEX and IEC Ex. The damping spring made of metal and rubber composite material can have a longer lifespan. In addition, the mechanical deck can be adjusted for reliable performance during the operation of products.
