Danger - Warning
Disabling safety devices is strictly prohibited.
The plant operator must:
- instruct operating and maintenance staff about device/component SAFETY DEVICE
- monitor operating and maintenance staff regarding compliance with safety measures
Must ensure:
- equipments are not actuated manually during operation, since hopper and devices maybe under
pressure
- that hoppers and devices are vented before opening
- electrical components are protected from touching, plash water and dust and are closed at all times
during operation
The operator must not use the device/component in any way that makes unsafe
The operator must immediately report any changes to the device/componentes that could impair
safety to the plan operator.
The Lump Breaking Feeder Valve has the function to adjust the product flow of the material fed from upstream,
to brake any lumps caused by moisture, prolonged storage and by the nature of those materials that tend to
clog.
It is a disintegrator of lumps type that can get broken manually, with no use of tools (e.g.: hammer).
The Lump Breaking Feeder Valve intended use is at the inlet of pneumatic conveying lines to avoid lumps from
blocking the air flow or at the inlet of other conveyors installation.
The blades move toward one at the time against the fixed grid to disintegrate the lumps; as a consequence,
the torque required to break the lumps is lower than the one required by the devices which employ all blades
to simultaneously press against the lump.
Operating temperatures ranging between -20°C and +40°C.
In some versions, to lower the material residues on the fixed blades of the grid it has been provided for the
blades to sharpen, which also ease the breaking of the lump.
This feature, along with the integral seal and additional bushings, ensure a low material residue is generated.
3.3 Operating principle
The rotation of the blades compresses any lumps present in the material against the fixed grid causing them
to get disintegrated.
This operation preserves the machines downstream the Lump Breaking Feeder Valve from being fed material
lumps that can clog it or lower its efficiency.
