Separation Technology
Desanding 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 suspensions. Desanding plants have further applications in gravel pits, in the mining industry and in micro-tunneling projects. The regeneration or cleaning capacity of a desanding plant is determined by the plant´s intake capacity of contaminated suspension. It is defined in m3/h. The regeneration efficiency or the “significant cut-off point” d50 indicates the smallest particle size of which at least 50 % can be removed from a suspension. It is expressed in 1/1000 mm or micron.

The main components of all desanding plants are:
- coarse screen for intercepting stones larger than 5 mm
- storage tank of the coarse screen cyclone with
- cyclone feeder pump for removing fine particles from the suspension
- dewatering screens for abstracting further water from
the solids discharged by the cyclone
