API HDD Casting Drilling Mud Equipment 50 m³/H 25Kw

New complete mud cleaning system for various of drilling for sale at AIPU Solids

APMS mud cleaning system is widely used in the mixing and recycling of slurry for the construction of hydropower, continuous concrete wall, slurry shield tunnel, horizontal directional drilling, etc.

Mud cleaning systems were once considered optional equipment. Environmental regulations continue to become more stringent and we must all responsibly make a contribution to protect our fragile ecosystem. And more and more drilling companies found the drilling cost can be controlled well against the mud system utilized.

Using mud recyclers is a valuable asset to drilling contractors, as well-conditioned drilling fluid can save resources, time, and money by reducing the amount of water and chemicals needed by reusing your bentonite and water. This helps maintain borehole stability with consistent mud properties through the entire circulation of the fluid and you haul off mainly the drilled solids, not the entire mud returns, including the liquid.

How to select a proper unit for your project

Drillers considering a mud recycler often ask: “Where do I start?” There are factors to consider before purchasing (or renting) a mud recycler, and, just like sizing the drill rig, sizing the recycler is equally important to your success. The following are some of the questions to ask yourself before making your purchase:

1. Type of drill rig will you be using?
2. Length of your average bore?
3. GPM of my mud pump or do I need a mud pump on the recycler?
4. Type and size of shakers on the unit?
5. Shaker screen sizes and availability, what is “mesh size”?
6. How do I know if the recycler is working?
7. Purpose of hydrocyclones, and how are they rated?
8. Do I need a trash pump?
9. Parts, service, and warranty?

These factors are important to know so that you use a recycler that is sized to clean the mud and protect the components on the rig, pump and cleaner.

Drilling rigs are generally classified as “maxi,” “midsize” and “compact. While you can put a maxi recycler with a compact rig, it would not be advisable to do the reverse. Lesson: size accordingly.

Generally, longer boreholes require a larger pit volume in order to properly process the drill solids before sending the fluid back downhole.

As a general rule, size the recycler cleaning capacity to one and a half to two times the pumping volume (max GPM) of the triplex pump. HDD drillers normally run thicker fluids due to the low vertical height and long horizontal lengths of their bores; thicker fluid makes it more difficult for the shakers and cones to process (separate) the solids from the liquids. This is largely due to the natural coating ability of bentonite — It wants to encapsulate the solids and “hold on” to them. By upsizing the recycler, the solid particles have a second or third opportunity to process through the mud recycler for removal before going back to the rig.

Example: If you are pumping 200 GPM, you would need a 350- to the 400-GPM recycler.

Some mud recyclers provide an “onboard” mud pump that was sized specifically to the recycler. This enables the driller to use all available drill rig horsepower toward the rotation and push-pull of the drill pipe, thereby not “robbing” it for an onboard triplex pump.

“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 in 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.

“There is no universal formula,” says Heinen. “There’s no perfect recipe for a fluid mix. It just depends on what you’re doing, where you are, and how each soil encountered reacts since soils react differently.”

The key to maintaining the integrity of the walls of the bore is bentonite, the primary component to mud mixes. Bentonite is a mineral found in clay beds. Its properties are such that when it’s mixed with water, it forms a filter cake much like the layers of a biscuit. This filter cake helps seal the walls of the bored tunnel allowing the drilling fluid to remain in the hole, which helps mechanically support the structure of the borehole.

Water is one of the critical elements of the mud mix. Water can vary depending on its source, whether it is extracted from a creek or river or sourced from the city. Water with a high concentration of sand or clay will weaken the binders in the mix and compromise the effectiveness of the drilling fluid. Contaminates in the water could also damage, or at the very least shorten, the life of your mud pump, says Heinen.
