Full Tail Sand Dry Discharge Cementing Filling Process - China

price: contact company for price

Process introduction:

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.

Technical innovation:

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

through network.
