MULTIDOS® - the MechaTronic System
Weighfeeder for continuous gravimetric feeding -
precise, economical, reliable
(option)
.68
A system for all feeding and weighing applications with accuracies up to ±0.25% has
been created in the form of the Schenck Process MULTIDOS® family with application-
specific series to fit every need. MULTIDOS® MTD-M series weighfeeders cover a wide
range of applications requiring medium to high feed rates. The MULTIDOS® MTD-H
weighfeeders are perfect for applications requiring high feed rates, high-bulk-density
materials, and extremely high removal moments, even with large silo discharge
openings. A broad spectrum of active and passive bulk material feeders that are
specially designed for specific bulk material properties supports the wide range of
possible applications.
Possible Applications:
E3 Feeding of chunky, granular bulk materials (e.g., clinker, gypsum, lump coal)
Feeding of all powdery or mealy bulk solids (e.g., raw meal, fly ash, filter dust)
with appropriate charging devices
63 Feeding of poorly flowing bulk materials
(e.g., clay, marl, gypsum from flue gas desulfurization systems)
E3 Charging of raw and cement mills
0 Kiln charging
H Mixture formation in gravel quarries and in the hard stone industry
H Mixture formation in smelting and coke plants
El Coal mill charging
E3 Feeding tasks in all mining-related industries
H Chemical industry, food industry (special design)

Advantages
0 Constantly designed for accuracy and reliability, the Loss-in-Weight
Feeder has been continually refined for the last 50 years to become
today's MULTIDOS® system
0 "Less is more" design, e.g., the measuring roller is placed directly
on two load cells. The MechaTronic concept ensures stable feeding
results over the long term
0 Low maintenance due to lifetime lubrication of the bearings and
weighted belt tensioning system
H On-site or remote weighing system calibration via PC, local field
office or host computer
H Cutting-edge, process-adaptive, modular electronic measuring and
control system equipped with fieldbus technology
H Wide feed rate adjustment range
