Dosing hopper

for concretepowder

Micro Silica weighing hoppers (dry or slurry) Silica Fume or Micro Silica is a by-product with a diameter around 150Nm that has been vented into air during silicon metal or ferrosilicon material manufacturing for years until researches have found a beneficial use for it in the concrete production industry. Reacting with the cement in the concrete it allows foralmost 1000 times less water permeability, less water bleeding, less iron corrosion, increased cohesion (for shotcrete applications) and higher abrasion resistance. Silica is normally supplied in 2 forms: Dry Powder or Premixed Slurry For Dry Powder: We offer a weighing hopper (cement-like). Since micro silica is 100 times thinner than cement it can not be transferred as cement. The silica screw conveyor has to be used with much lesser angle to provide the adequate material flow. In this case the silica silo has to be raised to a certain level. Steel legs for micro silica silo can be offer to minimize the foundation requirements. For Premixed Slurry: If micro silica comes as a premixed slurry a micro silica tank with an agitator (to provide constant homogeneity) can be offered along with micro silica slurry pump and weighing scales. Ice Weighing Hopper: We offer galvanized ice weighing hoppers that can be installed over the aggregate transfer belt or a skip hoist. Ice is being discharged onto the aggregates while transferring to ensure the fastest and equal cooling of all material. Ice Screw Conveyor: We offer isolated ice screw conveyors with special coating to prevent ice adhesion. Screw conveyor is being adopted to the ice making machine according to layout.
