The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Compatible and Sturdy
These devices are intended for storage, agitation and distribution of concrete or slurry. The upper part of the bin is sealed off by means of articulated screens, two of which are specifically designed for mining processes. The hopper gate is actuated by means of an electromechanical system and the mixing devices are controlled by an electrical gear motor with splined output shaft. A safety device prevents the opening of the screens during rotation of the mixing device (Trapped Key System).
Solidity and Power
In each case, BMH determines the optimal feed configuration for aggregates or mining residues with the cement required for the manufacturing of paste backfill, according to the specifications of the equipment such as cement, silos, conveyor systems, meters and mixers, as per the drawings and the specifications.
BMH Systems designs robust silos for continuous material flow, ensuring smooth delivery and appropriate dosage of cement and other materials needed for the manufacture of paste backfill.
