Full Tail Sand Direct Slurrying Cementing Filling Process - Chinaprice: contact company for price
Full tail sand direct slurrying cementing filling process
refers to the filling method that taking whole grain-grade
tail sand without classification and desliming as the
filling aggregate, to be pumped to vertical (or horizontal)
sand silo from concentration plant for natural
sedimentation, and be conveyed to mix with a certain
percentage of cementing material and water after metering,
and then be filled into underground worked-out section.
“Slurry like paste” cementing filling system designed by
our company for Shandong Dongping Hongda Iron Ore Company,
takes concentration plant tail sand as the raw material,
uses alkali-activated cementing material as the cementing
material. Full tail sand in vertical sand silo can be made
into slurry through wind and water linkage activation, and
be conveyed to electromagnetic flow meter for metering
through pipeline; cementation powder stored in material silo
will be automatically metered and proportioned by screw
conveyor and screw metering scale; the filling material will
be stirred in high speed by high concentration stirred tank;
the prepared filling slurry will flow naturally to the
filling area through filling drilling hoe and laying
Through drawing lessons from bushy technology at home and
abroad, the company upgrades the vertical sand silo
technology to shorten sedimentation time of full tail sand,
and mix them with cementing material when the concentration
is about 50%. The covering area of this process is
relatively small, and the overflow water will flow back to
The company achieves full tail sand utilization, to
reduce the pressure of tailing.
The company adopts the new alkali-activated
cementing material, to solve the problem of degradation in
water and no-cementation of superfine tail sand.
The company adopts wind pipe cleaning system, to
reduce pipeline flushing water consumption and relieve the
pressure of underground roadway drainage.
