MOVABLE SLURRY-PUMPING SETUP Russian patent published in 2000 - IPC

FIELD: mining industry. SUBSTANCE: movable slurry-pumping setup is preferably intended for operation in combination with single-bucket excavator in mining nickel ore containing boulders. Setup has chassis-mounted frame, which carries following units: sump, ground handling pump, bin for receiving rock mass from excavator, hydraulic giant, and device for separating boulders from rock mass. Device is made in the form of drum-type tapered screen. Longitudinal axis of screen is inclined with respect to horizon. End face of its large diameter adjoins through clearance to inclined wall of bin. Bin is made in the form of turned-over obelisk with hole configured as circular segment with chord coinciding with top of obelisk. Drum of screen is secured cantilever-like on power-driven shaft by means of spokes. Hydraulic giant is installed so as to deliver water into screen drum through end face of smaller diameter counter to flow of rock mass discharged by gravity from bin. Installed under tapered screen at side of its smaller diameter is inclined conveyor for loading it with oversize screen product and discharging it beyond setup limits. Aforesaid embodiment of slurry-pumping setup possesses high through-put capacity for separating boulders from rock mass. Setup and entire hydraulic transportation system are very efficient. EFFECT: higher efficiency. 2 dwg
