De-sanding plants are employed to remove soil particles in drilling muds and support slurries used in foundation engineering. They can be either water-bentonite, water-polymer, or water- cement and bentonite slurries. De-sanding plants have further applications in gravel pits, in the mining industry and in tunneling projects. The maximum capacity depends on various parameters. It is defined in m3/h. The values are based on water flow. The regeneration efficiency or the „significant cut-off point“ -d50 stands for the smallest particle size of which at least 50 % can be removed from a slurry. It is indicated in 1/1.000 mm or micron.
The BE 100-60 L is a very compact unit ideally suited for small slurry feed. Short installation time and low electricity power allow economic use on small jobsites.
Typical applications:
– Slurry-supported grab works for diaphragm wall
– Bored piling excavation
– Well drilling
– Geothermal drilling

The Bauer BE 170-60 desanding plant has been designed for the processing of larger amounts of all kinds of slurries commonly used in the construction industry.
An optional supporting frame enables the desander to be positioned directly at or above the borehole or the trench. The supporting frame can also be used as protection frame for transportation.

The de-silter unit consists of a battery of 4“-cyclones (6 to 12 nos.). It can be mounted on all standard Bauer de-sanding plants and is deployed primarily on tunneling and cutter diaphragm wall projects. Pre-treated slurries or drilling muds can be post-treated in a bypass operation with a process capacity of up t o 250 m3/hour down to medium silt-sized solids. The separated solids can be discharged onto the filter cake by the standard de-sanding plant or onto a separate de-watering screen.
