Renovation of the original mine silo sieve, large ore cracking and permeable screening saves time and effort

The original mine silo screen was completely modified from material to structure.

The selection of the original ore granary screen is an important gateway outside the process of rejecting large ore. The former mine granary screen has a hole diameter of 350×350 (mm), which is made of light rail material. When the forklift feeds the original mine silo, the scraping teeth and the crushing stones on the screen will cause serious damage to the light rail. In addition, after years of disrepair, it has become a lot of scars. On the basis of summarizing the previous lessons, the plant divided 12 long strips into 7 and 5 groups, which were assembled with 28 steel columns with a length of 3 meters and a diameter of 80 mm. The structure, the length × width × thickness of the steel plate is 13000 × 250 × 20 (mm), "vertical knife" arrangement, so that the dynamic like a garnet-like agglomerate into the sieve, under the action of its own gravity, Hit, crack, crush, etc., through the sieve into the process. Screening large ore, through manual hammering, steel plate vertical knife for the case, can also save labor and labor to crack and then through the sieve.

The thorough transformation of the original mine silo screen realized the natural scattering of the agglomerates, reduced the hammering strength, and facilitated the maintenance, ensuring the range of the selected materials, and creating conditions for smooth flow and stable indexes.
