MC-Balance manual 29
7.10 Filling the hopper.
MANUAL FILLING
The controller automatically detects when the hopper is manual filled.
In the period that the hopper is being filled, the MC-Balance is dosing with a fixed RPM, this means
the unit runs temporarily volumetric. As soon as the hopper filling is ready, the MC-Balance
immediately continues to work gravimetric
.
AUTOMATIC FILLING
Only use Movacolor hopper loaders to fill the hopper automatically.
Foreign hopper loaders can influence the gravimetric function of the dosing.
Introduction
Movacolor dosing units are capable of handling a variety of dry materials. Two different filling
systems are available depending on the material properties.
-The Movacolor Ejector (ME) system for dust-free or nearly dust-free materials
-The Movacolor Vacuum (MV) system for materials that are NOT entirely dust free.
-The Support frame for external / foreign hopper loaders (EX)
The ME and MV systems are both driven by low-pressure compressed air and mounted directly on
top of the hopper lid of the Movacolor dosing unit. The MC-Balance controls the operation of the
ME or MV systems.
All parts are aluminum or stainless steel and are virtually maintenance-free. Only the filter needs to
be cleaned periodically. To increase reliability and safety, there are no moving parts except for the
pneumatic operated closing valve of the MV system.
How the ME works
The ME system blows the material from the bag, drum or
container into the hopper of the dosing unit. The hopper lid of the
housing has a simple and easy-to-clean dust filter to keep any
dust particles in the hopper.
The system is triggered by the filling start weight
(CONFIGURATIONS <menu>). This parameter also generates a
low-level alarm if the hopper is empty.
How the MV works
The MV system uses a 3-stage vacuum generator driven by
compressed air to create a vacuum that draws material into a
chamber that closes. Once the chamber is filled with material, the
cone that closes the chamber will open and the material will be
discharged into the hopper.
The system is equipped with a superior filter to ensure that the
finest particles (> 5micron) stay in the system and are not
released into the atmosphere. This makes the MV system the
most practical and user-friendly system for both powders and
granules.
