 Central
Vacuum Loaders
Foremost Machine Builders
manufactures central vacuum loaders and
conveying receivers for the transporation of raw material pellets
and reclaim material from a storage silo to a blender, from one
process station to another, and/or to the final processing point.
When your plant requirements demand high productivity on a continuous
basis, you'll find our series VF and VMF Vacuum Loader Packages
will provide the dependable, efficient operation necessary to succeed
in today's competitive processing environment. For
over fifty years, Foremost has been engineering and manufacturing
solutions to bulk material conveying problems.
We have provided the highest quality equipment in our engineered
systems and dependable vacuum loader packages. Our standard high
quality components are matched with a conservative engineering factor
to provide the end user with years of low cost, low maintenance
productivity.
Material loading is accomplished through the following sequence
of operation:
The positive displacement pump creates a vacuum on the vacuum chamber,
closing the flapper valve. The material is then drawn through the
suction lance or from a vacuum-take-away box via tubing or flex
hose to the vacuum chamber.
The vacuum chamber can be loaded by either a timing cycle, which
is easily adjusted at the control panel or by an end-point-control
sensor mounted in the vacuum chamber.
After the loading cycle, the vacuum breaks, causing the flapper
valve to open and the material drops into the process hopper.
