Loading Systems

The design of a grab is dictated by the nature of the bulk material that needs to be handled. This guarantees optimal performance of the grab. Other important factors to incorporate in the design process are the grab crane and the conditions at the work site.

Airslide Conveying

With airslide conveyors a wide range of fine-grained bulk solids can be conveyed at a very low velocity. They are widely used for materials such as cement, fly ash, iron powder or gypsum. This type of conveying can be regarded as an extreme form of dense phase conveying. In situations where the flow of material can be downwards, airslide conveying reduces significantly plant capital costs and operating costs compared with pneumatic conveying systems.

Advantages of airslide conveying systems:

  • Dust emission-free operations
  • Equipment assembly in small space.
  • Easy to install in already existing plants, even with space problems.
  • High simplicity, do not require exhaustive maintenance.
  • Low capital and operational costs.

Airslide Conveyor

With INGESOA® Airslide Conveyors large quantities of fine-grained bulk solids can be conveyed to a range of locations with a slope of 5º to 12º. Operational costs are minimal.

These square-shaped steel equipments are divided in two chambers by an abrasion resistant, 5 mm thick, polyester membrane (heatproof up to 120ºC). The material being handled travels via the upper chamber and the air circulates in the lower one. The resultant vertical air flow partially supports the bed of particles and the fluidised powder takes on liquid-like properties.

The fluidized material flow can attain, depending on the system size, up to 965 m3/h, although the value of 300 m3/h is usually not exceeded.

Diverter Bin

The use of curved airslide conveyors reduces flexibility of this system. With INGESOA® Diverter Bins it is possible to fit airslide conveying lines in already existing plants, even with space problems. Moreover, different configurations available allow for one input, multiple outputs.

These units are divided in two chambers by an abrasion resistant polyester membrane (heatproof up to 120ºC). The material being handled travels via the upper chamber and the air circulates in the lower one. The resultant vertical air flow partially supports the bed of particles and the fluidised powder takes on liquid-like properties.

Bottom Diverter Valve

Locking Valves have been specifically designed to be inserted in airslide conveying lines or after diverter bins to shut off the flow of material. This type of valves employ the sliding-rotor locking system, which confers the following benefits:

  • Full Tightness
  • Compact Design
  • Minimum Maintenance Need

The bottom of the valve is permanently aerated to avoid dead zones during conveyance.

Actuators available: manual, pneumatic, motorized.

Independently of the type of drive, our Side Diverter Valves can be manually operated by means of a clutch.

Side Diverter Valves

Side Diverter Valves have been specifically designed to be inserted in airslide conveying lines to divert the flow of material to one side an simultaneously lock the frontal flow. This type of valves employ the sliding-rotor locking system, which confers the following benefits:

  • Compact Design
  • Minimum Maintenance Need

Foreign Bodies Separator

The material coming from the mill may contain foreign bodies that could damage the ceramic coating of the dynamic separators. With our Foreign Bodies Separator it is possible to intercept these solids before they damage the rest of the installation.

When foreign bodies enter the upper airslide conveyor, they impact against the perforated plate and fall by gravity into the lower trap.

The bottom of the trap is aerated to avoid bridging when the solids are discharged towards the reception hopper.

Blade By-Pass Valve

Blade By-Pass Valves have been specifically designed to be inserted in airslide conveying line discharges or at hopper outlets, to vertically divert the flow from one direction to another. These units are ideal in case complete tightness is not needed. Actuators available: pneumatic, motorized. Independently of the type of drive, our Side Diverter Valves can be manually operated by means of a clutch.
