Title:
HIGH ASH FINE-GRAINED SLIME SEPARATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/155420
Kind Code:
A1
Abstract:
A high ash fine-grained slime separation device and method, which is suitable for use in the field of coal washing. The device comprises four parts: a feed system (1), a mineralization system (2), a separation system (3) and a pulsating water flow control system (4). A slime mineralization area is isolated from a separation area, and a damping block (22) and pulsating water flow apparatus are built into the separation system (3). A flotation feed material is fed to the feed system (1) to complete a slurry adjustment operation. Slime after slurry adjustment enters the mineralization system (2) and turbulent collision occurs, forming mineralized bubbles. The mineralized bubbles traverse a turbulence elimination tube (12) and then enter the separation system (3). At the same time, the pulsating water flow control system (4) feeds a pulsating water flow of a certain frequency and waveform into the separation system (3).
