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
