Full Tail Sand Dry Discharge Cementing Filling Process - Chinaprice: contact company for price
Full tail sand dry-discharge cementing
filling process refers to that after cyclone
classification and thickening, the full sand
with a certain concentration will be dry-
discharged to dry stockyard as aggregate, and
then be mixed with cementation material to
prepare filling slurry for conveying to
underground. Cementing filling deep hole
mining method, designed by our company for
Shandong Zibo Jinding Ore Mining Co., Ltd
Wangwangzhuang Iron Mine, takes the full tail
sand of Jinling iron mine tailing storage as
filling material, the cementation powder
produced by our company with independent
intellectual property rights as the cementing
material. The full sand will be conveyed by
belt conveyor and metered by electronic belt
scale, while the cementation powder will be
stored in material silo, conveyed and
proportioned by screw conveyor and screw
metering scale. The filling system adopts
two-stage stirring composed by double-shaft
stirrer and high-efficient activation
stirrer. The prepared filling slurry will
flow naturally to the filling area through
filling drilling and laying pipeline.
In order to make pipeline conveying
convenient, reduce pipeline flow resistance
and improve slurry suspension property, the
full tail sand dry-discharge cementing
filling process will select reasonable
concentration and grain size distribution.
Two- stage stirring slurrying composed by
double-shaft stirrer and high-efficient
activation stirrer can break the flocculent
structure in slurry, improve the activation
property, and make the slurry possess good
liquidity and relatively low segregation
It solves the problem of selecting reasonable
concentration for filling slurry by making
full use of our two-phase flow loop lab.
It adopts the new-type cementing filling
material with self-developed and independent
intellectual property. Under the same
strength requirement, the amount of cementing
material is 2/3 of that of cement, which can
reduce the filling cost.
Central control system adopts WinCC
human-computer interface, which can carry out
remote commissioning and system maintenance
