Pan and Tube Conveyors
Company offers a series of pan and tube conveyors designed to provide
a simple and efficient means to meter and convey dry bulk materials.
Designed to economically feed powders, flakes or agglomerates without dust or degradation, the systems
feature two highly efficient, externally mounted vibrators that provide a unidirectional vibratory motion along the
conveyor axis in constant or variable operation. Flow rates are adjustable by resetting the eccentric force during op-
eration or with an optional speed controller. With no screws, drag chains, bearing seals or other internal moving parts, the
units require little or no maintenance and are suited for sanitary applications. Individual units are available in lengths up to 25', connectable in series up
to 100' and offer capacities in both open pan or closed tube arrangements up to 36,000 cu/ft/hr.
