Abstract

In a slurry preparation process for preparing uncrushed oil-sand ore to become suitable for subsequent slurry transportation, a step-wise series of process steps comprising receiving the uncrushed ore and water into a mixing hopper to create a mixture of ore and water; discharging the mixture onto a screen deck to separate oversize and undersize fractions; allowing the undersize fraction to discharge into a slurry preparation vessel; discharging the oversize fraction to a self-clearing crusher which comprises a receiving hopper and a driven crushing roll working in conjunction with an endless crushing conveyor chain, each driven by a reversible drive means. Forward motion of the crushing conveyor forcibly conveys the ore into a gap space set between the crushing roll and the crushing conveyor and crushed ore is discharged into the slurry preparation vessel. In the case of an uncrushable object entering the crusher gap and being detected by high load on the crushing roll drive or the crushing conveyor drive, the endless crushing conveyor is motivated in a reverse direction to discard the uncrushable object to a rejects pile outside of the slurry preparation vessel.
