This screw conveyor has an integrated crusher
The SpiralFeeder® flexible screw conveyor (photo) features an optional integrated crusher. Offered as a single unit for seamless operation and convenience, the powder-conveying system sets the crusher under the infeed hopper discharge to automatically reduce the particle size of agglomerated solids and present a consistent stream of free-flowing powders to the screw conveyor for transfer. Any lumps and chunks that agglomerated in storage are returned to the required particle size while material transfer up the conveyor moves smoothly without clogs, blockages or buildup at the infeed. Devised for transferring flour, salt, silica, pigments, Bentonite clay, gypsum and other dry bulk materials that tend to clump in storage, the incline conveyor with integrated crusher automatically transfers the bulk materials from a hopper through the lump breaker and up inside an enclosed tube to discharge into a surge hopper or other location. A built-in safety grate on the infeed hopper helps prevent unintended access to the hopper interior and crusher. — Automated Flexible Conveyor, Clifton, NJ.
