Abstract
A method for preparing a suspension from a separation process, wherein the suspension is made of a particulate abrasive and a liquid slurrying agent. The method includes the steps of: a) thinning the suspension in a tank with an additional slurrying agent (PEG) without adding additional water, producing a constant volume ratio between the particulate abrasive and the liquid slurrying agent; b) separating the thinned suspension into a liquid and a solid fraction in a centrifugal separator, and c) subsequent refinement or reuse of the separated liquid and solid fractions.
Claims20
A process for working up a suspension from a parting process, where the suspension consists of a particulate abrasive and a liquid slurrying medium, which comprises the steps:
- a) dilution of the suspension with additional slurrying medium in a tank without additional addition of water and with establishment of a constant volume ratio between the particulate abrasive and the liquid slurrying medium;
- b) separation of the diluted suspension into a liquid fraction and a solids fraction in a centrifugal separator, where the liquid fraction separated off in the centrifugal separator is subjected to an after-purification effected by means of at least one filter and
- c) subsequent upgrading or reuse of the separated liquid fraction and solids fraction.
