The LBC Lump Breaking Feeder Valve consists of a rotary shaft hold in position by two half-bodies. Built on
the shaft, it rotates a series of blades angularly o󰀨set to each other, allowing them to compress the material
lumps against the xed grid, fastened to the lower half-bodies. The ne material falls trough the cutting grid
and reaches the next device via the product outlet.
The device has been designed taking into consideration the “Essential Safety Requirements of the Appen-
dix I of the European Directive 2006/42/CE, known as the Machinery Directive", already adopted in the
National Italian legislation by means of the Legislative Decree no.17 of January 27th 2010.
Important
The terms “device”, “Lump Breaking Feeder Valve” used in this manual refer to the same device.
As components meant for installation in a plant, the Lump Breaking Feeder Valves - not fully provided
with safety means - have to be considered “partly completed machinery”. Therefore, they do not bear
an EC marking.
It is forbidden to start the Lump Breaking Feeder Valve unless the machine/plant in which it is to be
installed has been declared compliant with the Directive 2006/42/EC and further modications.

Danger - Warning
Disabling safety devices is strictly prohibited.
The plant operator must:
- instruct operating and maintenance sta󰀨 about device/component SAFETY DEVICE
- monitor operating and maintenance sta󰀨 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 ow 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 ow or at the inlet of other conveyors installation.
The blades move toward one at the time against the xed 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 xed 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 xed 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 e󰀩ciency.

Important
THESE DEVICES WERE NOT DESIGNED TO MANAGE FOOD PRODUCTS ACCORDING TO EC1935/2004.
The use in installation conditions di󰀨erent from the original conguration, with di󰀨erent materials as regards
shape and particle size and for operations di󰀨erent from the ones permitted is strictly forbidden.
It is forbidden the use of the device in case of operation abnormalities and in conditions which do not comply
the use and safety recommendations hereafter.
The materials having their unit weight over 25 kg must be handled and positioned on the crates by means of
appropriate means and lifting accessories and, to avoid their accidental falling, must be provided with suitable
lifting points.
Permitted materials
It is strictly forbidden to use materials which do not match perfectly the technical operation features and the
performances of the device or of its components.
For instance, the following materials are not permitted:
- subject to hazardous changes of their static and/or chemical-physical conguration during the pro-
cess.
- which, because of their chemical-physical, are classied as being hazardous (e.g.:explosive, toxic,
ammable, dangerous from a bacteriological and/or viral point of view or other similar materials).
Danger - Warning
It is forbidden to use the device with ammable and/or explosive materials.

3.6 Noise level
LBC

Important
The noise level depends on several factors such as dimensions, the nature of the material to be con-
veyed and the lling rate.
In accordance with the legal provisions in force, the client must carry out on-site measurement of the
noise level, after assembly and however before commissioning the device, during operation of the de-
vice in the worst conditions, to ensure that the level of noise reverberation doesn't put into any danger
the operator during the operation of the device.
The vibrations of the device doesn't represent a hazard for the personnel that operates it.
An excessive vibration could be caused by a fault that has to be immediately signalled and repaired to avoid
decreasing the reliability level of the device.
Danger - Warning
Provide the necessary protection from lightning during operation and the related devices to ground
any electrical discharge.
3.8 Overall dimensions and technical features
For an exact identication of the equipment concerned, see the identication plate.
The transport documents indicate the overall dimensions of the Lump Breaking Feeder Valve in addition to the
serial number and the identication code.
The information on the technical features of the LBC Lump Breaking Feeder Valve such as diameter, seal type
and blades characteristics are available in Chapter 10.
3.7 Environmental operating limits

3.10 Safety devices
The access to the inner parts of the Lump Breaking Feeder Valve is not possible during operation.
Unscheduled access is envisaged to remove foreign bodies and material deposits inside the device for ex-
traordinary maintenance.
Danger - Warning
Prior to start up the device the xed and/or mobile guards of the device must be set in place.
To prevent accidents, it is essential to maintain the LBC Lump Breaking Feeder Valve out of the reach of the
personnel during operation. To this purpose, the customer must provide suitable safety devices such as grids
and inlet and outlet protection joints (sturdy joints, hoses or rigid pipes ttings). However, the installer must
prevent that personnel gets injured, even accidentally (using suitable hopper, safety grids, etc.).
Danger - Warning
Shutdown procedures
• Before cleaning and maintenance work, the following shutdown procedures must be complied with:
- Disconnect the electrical system
=> Switch o󰀨 the main switch
=> Check that the assembly is not live.
=> Ensure that the main switch cannot be switched on again.
- To shut down pneumatic system
