What’s Advantage of Unidrill Slurry & Drilling Fluid Recycling Equipment

 

Top-quality Betonites is the clay mineral with the strongest swelling properties of all. As a result, the price of Betonites is high accordingly.

Depending on the drilling fluid volume, the drilling fluid is therefore a valuable operating resource. Fortunately, a suitable recycling system could reprocess the slurry for reuse.

 

By separating the sand which is taken up by the fluid in the process of drilling, the cleaned drilling fluid can be used again in a closed drilling fluid cycle.

 

In this case, it reduces the mixture time and speeds up the drilling progress, reduces wear of the drilling tools and pumps considerably and decreases the water and Bentonite consumption, which on the whole increases the profitability of a HDD operation or pile foundation project in a sustainable manner.

 

 

 

Screen mesh

The filter system made of PU mesh is characterized by its light weight, long serving life, energy saving, and outstanding anti-corrosion capability.

 

Floating device

Perfect combination of buoy and foam plate realizes automatic adjustment of slurry amount and fluid between overflow tank and slurry container.

 

Hydrocyclone

Making good use of hydrocyclone self-separation and deposit working principle as the second important part of filter system to ensure the slurry separation degree within 60 μm.

 

Controlling system

Electrical controlling system ensures safe and convenient operation as well as triggering alarm signal and self-protection system in emergency.
