Breaking Cementing Filling Technology - Chinaprice: contact company for price
In a narrow sense, the breaking cementing filling technology
is waste rock cementing filling technology. As the aggregate
is waste rock, construction waste and other large aggregate,
it has to be broken into suitable graded aggregate before
pulping, and then mixed with cementing material to become
filling slurry, thus to be conveyed to underground for
filling. The equipment mainly carry out secondary breaking
for waste rock and other aggregate, to ensure suitable
graded aggregate and improve the workability of material
slurry. Meanwhile, in order to reduce pipe resistance, it
carries out screen classification for the super fine
aggregate, so as to ensure that -20μm aggregate content is
not less than 15%.
It adopts the new production and preparation process of
“screening before breaking”. The gangue with qualified
size can be directly sent into the production process after
screening, while the coarse gangue will be broken by size
grading, which can greatly improve the production efficiency
and reduce the production cost.
It solves the problem that filling mine aggregate
source is insufficient, which has a great role in promoting
mine filling exploitation.
It adopts the advanced and reasonable mixing pulping
technology, which can solve the problems such as easy slurry
segregation and easy pipeline blockage caused by complex
It adopts vertical pipe decompression and horizontal
pipe drag reduction technology, which can reduce pipe
abrasion and increase filling pipe service life, as well as
improve the operational stability of filling system.
