Centrifuge used for recovery barite to remove small solid particles, reduce the mud solid content, to ensure the performance of the drilling fluid. And DC production drilling fluid centrifuge has high purification efficiency, convenient adjustment and easy maintenance.

Even the finest solids can be separated in the decanter centrifuge if its sedimentation rate in the carrier liquid is sufficiently high. The sedimentation rate depends on the particle size, the particle shape, the density difference between solid and liquid, and the viscosity of the latter. In many cases, significant improvement is possible by conditioning, for example heating or addition of flocculants. Also important is the geometrical design and establishment of operating parameters.


DC Solid control decanter centrifuges operate on the contraflow principle. This means that the suspension to be separated is fed approximately in the centre of the drum, the sedimented solid matter is conveyed towards the smaller diameter by the screw rotating at a speed differential in relation to the drum, whilst the clarified liquid overflows at the opposite end of the drum.


The height of the liquid level in the drum and thus the ratio of clarifying to drying section of the drum can be infinitely varied. This permits optimum matching to the separation application involved.

The speed differential between screw and drum is effected by means of a CYCLO gear unit. Drive is effected in standard form by V- belt, the centrifuge being fitted, according to speed combination, with a single drive (fixed eccentric shaft) or dual drive (driveneccentric shaft).
