Portable Primary Jaw Unit Fed by a Wobbler Pre-Screener

The Mobile Jaw Plant with Wobbler Feeder combines primary crushing and pre-screening on a single chassis as a high-capacity portable unit. It works at 250-450 t/h and is the highest-capacity primary solution in the range. The wobbler feeder gives superior performance in sticky, wet and clayey material.

Working principle and distinguishing feature

The distinguishing feature is the wobbler (paddle) feeder: as material advances on rotating shafts, stones roll and rub against each other; this tumbling action separates surface dust, clay and fines. The result is cleaner feed to the jaw crusher, so crushing efficiency rises and wear falls. It handles wet/sticky feed without the blinding that a standard grizzly feeder suffers.

Technical specifications

Feed/product table values are confirmed with the order specification; jaw plates are manganese.

Material and application

For sticky, wet, clayey primary feed the wobbler's key advantage stands out; it works where a grizzly feeder blinds. It is used in quarries, mine sites and recycling. As a jaw primary it is also the correct choice for abrasive rock (compression principle). Because the wobbler pre-separates clay, the jaw plates see cleaner feed, so plate life extends and cost per tonne falls.
