Weight Belt Feeders

BF 2012

Introduction

The BF 2012 belt feeder reveals new horizons for plant automation

reliable and durable mechanism;long and safe exploitation;all types of industries;improved human-machine interface;easy-to-use parameter setup;based on Siemens, SEW and Schneider.

PurposeThe BF2012 feeds bulk materials and can be used in the following industries:

Cement;Glass;Chemistry;Forage;Metallurgy;Other;

FunctionsBulk material weighingBelt speed measurementBulk material flow measurementBelt speed frequency controlContinuos material flow controlAuto centringAuto belt stretching compensationTotal material measurementAutomated tare and calibrationLocal and remote controlAlarm signalling for failuresPROFIBUS-DP communication with a host computer for data logging/archiving and reportsCommunication abilities for plant-wide systems incorporation

AdvantagesConstantly designed for accuracy and reliabilityLow maintenance, easy belt changeThe measuring roller is placed directly on two load cells. The concept ensures stable feeding results over the long termSafe belt run monitoring and trackingPlough scraper (diverting foreign objects on return belt to the side)Static belt tension through take-up screws integrated in frameWide feed rate adjustment range

PLCThe BF2012 system software is based on the following PLC platforms:

PLC S7-226 controls single belt feederPLC S7-1200 controls single belt feederPLC S7-314C controls up to 8 feeders. Supports recipes, group interlocks, complete monitoringPLC S7-416 can control unlimited number of belt feeders

SoftwareAlong with the BF 2012 comes a complete set of system software (WinCC or PCS7) and standard modules (Cemat or SATs standard modules) for embedding the feeders in the whole plant project.

Solutions

We offer implementation of the belt feeders in the plant in several ways:

As a part of a complete engineering project developed by the SAT company;Mastering of the feeders in existing projects;Modification of the system software for different types of communication to meet the particular needs.
