Mud Reclaimer|Mud recycler for drilling mud, HDD, mining, and water well
HDD mud recycling system is designed for Horizontal Directional Drilling ( HDD ) rigs.
Depending on drilling mud requirement, an HDD mud recycling system can include a shale shaker, desander cyclone, desilter cyclone, decanter centrifuge, mud tank, mud agitator, mud gun, transfer pump, etc. The shaker screen mesh size will depend on a shaker's performance for mudflow and drilling mud separation at different mud requirements.
Drilling fluid, mud, slurry — it’s all the same
“Mud” is the common reference to drilling fluid used in all types of drilling operations. “Slurry” is another term that is an interchangeable reference to drilling fluid. Mud serves multiple purposes such as: providing coolant for downhole electronics; suspending and displacing cuttings from the borehole; reducing wear on downhole tooling, and aid building a stable borehole by reinforcing and maintaining the walls of the bore or tunnel. Given the importance of mud, achieving the right mix is another science.
Such Mud Reclaiming/Recycling System is designed for mud cleaning and recovery of the bored pile, rotary drilling rig, anti-seepage engineering, cored drilling and etc., which can reduce costs and improve construction efficiency.

APMC Mud reclaimer/recycler Details
The old adage “don’t muddy the water” doesn’t apply to horizontal directional drilling (HDD) where the water is supposed to be muddy. Drilling fluid (mud) extracts particles and cuttings from the borehole, as well as stabilizes the hole itself. Mud has always been an essential element to a successful drilling operation.
Along with the drilling fluid, a reliable method of delivery to the drill is needed. This is called a mixing system or mud system. The mud system delivers the fluid to an onboard pump (on smaller horizontal directional drills) or a standalone pump that feeds into a larger rig (generally 100,000-pound capacity or larger.) With the rise of mud recycling in drilling, reclaimers are becoming more prominent on job sites. These are a type of mud system that “cleans” the used mud and recirculates it back into the mixing system to be reused. An HDD contractor needs to make sure to use the right kind of mud and the proper equipment to effectively supply the correct amount of fluid into the pump and downhole.
“The mud system is the device on the job site that is married to a particular drill rig,” says Jon Heinen, pipeline segment manager for Vermeer Corporation. “Its job is to provide that rig with the appropriate amount of drilling fluid, so it has to be a good match. A large pipeline project with a maxi rig is going to have a significantly different system than that of a smaller 9,000-pound (thrust/pullback) machine. Either way, all HDD machines need a mud system of some kind.”
There is a method to the “mudness,” and strict adherence to procedures needs to be followed. The key factors are proper planning, ensuring the use of proper equipment, and consistent drilling fluid maintenance during drilling operations.
Accumulated solids in the bore are often given as one key reason for the "stuck" drill pipe. A high volume of clean mud will "float" solids to the surface for disposal. Mud recycling increases the success rate of bores, reduces the expense for bentonite, and helps maintain a tidy job site. These mud recyclers provide two benefits: missing enough mud and removing solids from the returning fluid.
