  • For abrasive materials in extreme operating conditions.
  • Motorized gear in various sizes, with capacities over 250 t/h.


Deviation chute
  • The perfect equipment to divert the material flow between two ways.
  • Installed in vertical throughput position.
  • Manual, motorized or pneumatic drive.
  • Can be operated with high temperature and abrasive materials.
  • Angle of slope: 20, 30 or 45 º.                                                                                                                                         


Coated bends

Bends can be delivered with different types of internal coating.

These bends apply to pneumatic conveying systems for abrasive products.



This equipment guarantees maximum efficiency in separating solids from conveying gas by centrifugal action.

The gas is eliminated through the superior part of the cyclone and the solids through the inferior part.


Discharge of big bags and bags

Equipment designed to discharge powdered or grained materials from big bags (single or double) or bags.
It is also prepared to admit dedusting equipment. In carbon or stainless steel construction.


Lump breaker

Installed at the extraction point of the silo, the lump breaker smashes the material that has turned into stone, facilitating conveying and storage.

Appropriate for abrasive products.



Aeroslides with fluidization system used to convey materials in sloping installation.
Equipped with peep holes and inspection lids.


Round diverter for Aeroslides

Appropriate to divert the material flow between two ways in pneumatic conveying systems with Aeroslides installed in horizontal passage.

The operation can be manual, motorized or pneumatic.


Gate valve

Specially designed to block the material flow in pneumatic conveying systems. It is possible to use them for abrasive materials and for high temperatures. 

Operation can be manual or pneumatic.


Bag filters
  • Retain particles in positive pressure or vacuum conveying systems for powdered or pellets. Bag's cleaning system with low compressed air consumption.
  • Hopper or bin vent type.
  • Round or rectangular sections.
  • Appropriate for classified areas.


              Humidifying screws
  • Robust construction with wear plates.
  • Spraying nozzles (water) restrain from powder formation during wagon or truck loading.
  • Appropriate for minerals, foods and chemicals.


Diverter valve

The function of this valve is to divert the material flow from the main pneumatic conveying line to different points, such as silos, cyclones, classifiers, etc.

  • Appropriate for high temperature and abrasive products.
  • Angle of 25º.
  • Compact construction.
  • Available in 9 different models (diameters from 2 1/2" to 14").


Dosing valve
  • With both, dosing and locking function (for bulk materials).
  • Appropriate for high temperature and abrasive products.
  • Operates in combination with weighing systems, silos, loading systems, conveying, storage, distribution and dosing of powdered or granulated materials.
