EXTRAC Lump Breaking Feeder Valves – LBC

No clogging even with hardened materials.

ETRAC Lump Breaking Feeder Valves - LBC Unit

The Lump Breaking Feeder Valve enables safe and smooth segregation of bulk materials that tend to pack and form lumps during production and/or storage. Its design favours gentle crushing even with hardened material under a medium-high material column. Consisting of a solid cylindrical body with inlet and outlet flange, an integrated crushing tool driven by a side-located electric motor and a rigid grid. To adjust to the required particle size both blades and grid are easily removable to be adapted according to the desired material characteristics.

The Lump Breaking Feeder Valve is fed with agglomerated solids which, after being crushed are discharged through the outlet towards further processing. The LBC is the ideal solution to break up snow-ball-like materials. It is particularly suitable for hygroscopic materials and those that are compacted under pressure, such as sugar, salt, silicates, chemicals, and food products in general. The LBC Lump Breaking Feeder Valve can be fitted in loading and/or discharging pipes, for emptying or filling drums, bins, or screw conveyors.
