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.

Ice weighing hoppers and ice screw conveyors

Ice addition to the mix instead of water is a very wide spread application in countries with hot climatic conditions.

Flowmeters for water, additives and other fluids

Flowmeters provide high accuracy measurement and are widely used were weighing is not possible or very high accuracy and tempered or controlled flow is required. On the other hand, flowmeters are not affected by vibrations and wind and provide constant accuracy.
We offer flowmeters for water, additives and other fluids where necessary or by customer’s request. Flowmeter for water is usually used with Mixer Moisture Probe for necessary water ratio correction or for tempered water addition where necessary.

Additional Cement/Fly Ash/Lime/GGBS/Anhydrite weighing hoppers

Several additional weighing hoppers for different materials can be implemented on the main chassis of the concrete plant (on some models). Pigment (paint) addition to concrete is widely used in Precast Manufacturingfor decorative applications and manufacturing of colorful tiles. Extremely high accuracy is required for each batch in precast products and paint dosing is not an exception. We offer paint hoppers with micro feeders for exact weighing with 0 tolerance to ensure that each product’s color is exactly the same.

Automatic fiber dosing systems for soft or steel/polypropylene fiber

Fiber feeding systems are equipped with cylindrical spiral fiber feeding lines and installed on a robust steel structure. Two adjustable vibrators allow the required movement of the vessel. Units are pre-installed and tested in the factory and shipped in a condition ready to operate. Site installation is done quickly thus allowing immediate production.

Lead ball weighing and feeding system (for extra heavy concrete types)

Lead balls are widely used in nuclear industry for manufacturing of extra heavy concrete types with radiation protection properties. Mixing such type of concrete requires extremely durable mixer design and proper weighing system.We offer lead ball weighing and feeding systems that are specially designed for nuclear industry. Precise hydraulic gate feeds the balls onto the aggregates on the aggregate transfer belt to ensure the even distribution and prevent the roll back.
