Breaking cementing filling technology

Technology introduction

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 **0”. 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 aggregate.

    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.
