CONVEYING TECHNOLOGY
intermediate transfer point and unloading station , including silos and buildings , were supplied , complete with electrical and instrumentation systems . Performance guarantee testing was carried out over nearly one week , with the system consistently achieving its present capacity of 1,500 t / h .
The execution of the project drew on the global overland conveying expertise of TAKRAF Group , with the length of the required conveyor system and the challenging topography along the conveyor path calling for multiple , very tight compound horizontal and vertical curves .
Advanced material flowability testing and modelling were used in the design of the transfer chutes at the intermediate transfer point and the plant end junction house to minimise risks such as environmental pollution and spillage , accelerated belt wear and blockages .
In erecting the conveyor system , attention was placed on accommodating and minimising disturbance of the population of the various villages through which the conveyor system passes . TAKRAF India also placed particular focus on safety , strictly conforming both to TAKRAF ’ s global promise of zero harm and to the client ’ s safety protocols .
Gopal Kalyanakrishnan , Managing Director , TAKRAF India , commented : “ This challenging project called for state-of-the-art design and engineering expertise , as well as focus on maintaining the highest standards of safety , fabrication and installation . The team must be congratulated on this considerable achievement , which represented another ‘ first ’ for TAKRAF .”
Also in India , Thriveni Earthmovers and client NTPC , India ’ s largest electricity producer , have celebrated the start-up of a new IPCC system and Coal Handling Plant ( CHP ) at the 15 Mt / y Pakri Barwadih mine in Jharkand with the system having begun trial operations . The IPCC system was supplied by Germany ’ s TAKRAF and incountry subsidiary TAKRAF India Pvt Ltd heaquartered in Chennai based on joint engineering with the mine ’ s own teams and includes three 1,250 t / h semi-mobile crushing stations equipped with TAKRAF sizers imported from Germany , plus a 6 km overland conveyor with horizontal and vertical curves mounted on sleepers .
The project also includes stackers and reclaimers from TAKRAF to allow mixing of different grades of coal plus transfer points . Thriveni said the project is a first for the Indian coal mining industry and will significantly reduce the mine ’ s carbon footprint through reduced use of diesel-based truck haulage of coal . India ’ s largest electricity producer , NTPC Ltd , began production of coal from the Pakri Barwadih mine in 2017 . The mine is operated by Thriveni Sainik Mining Pvt Ltd ( TSMPL ), a JV between leading
Indian mining contractor , Thriveni Earthmovers and Sainik Mining & Allied Services Ltd , with the joint venture having been awarded a 25 year Mine Developer cum Operator ( MDO ) contract in September 2015 .
FLSmidth gets IPCC nod at Blagodatnoye
FLSmidth has been chosen to supply In-Pit Crushing & Conveying ( IPCC ) equipment for the upstream section of Polyus ’ Blagodatnoye gold mine . The order follows an October 2021 announcement that FLSmidth would supply a large package of process equipment for the expansion of the same mine . This new order for IPCC equipment comprises a semi-mobile crushing station with the TSUV Gyratory Crusher , an apron feeder and a 1.6 km long overland conveyor , which will transport the material to the concentrator .
The equipment has been customised for the project and includes a modular design with opposite truck ramps and enlarged discharge hopper . Components were selected due to their ability to perform in harsh conditions where temperatures reach -40 ° C . “ We are happy to confirm this significant IPCC order , which follows our recent agreement with Polyus to provide the mineral processing equipment at Blagodatnoye ,” says Alexey Kutilin , VP Head of Capital Sales ENAR , Mining . “ It underlines our strength as a full flowsheet provider of productivity-enhancing solutions for the mining industry .”
Branco Lalik , Global Director for Mining Systems at FLSmidth , adds : “ This large IPCC order is a clear show of confidence for our continuous mining technologies and for our market-leading TSUV Gyratory Crusher . In fact , the new steel structure-based , crushing station , with apron feeder discharge , is just the latest crushing station order in hard rock applications for FLSmidth , proving our successful strategy for flexible , customised design that meets each customer ’ s unique requirements .”
In more detail Lalik told IM : “ An important
FLSmidth ' s IPCC solution for Polyus Blagodatnoye includes a 1.6 km long overland conveyor , which will transport the material to the concentrator
message in our strategy for IPCC systems is that we want to offer customised and flexible solutions . The series of orders that we have received in the past two years for crushing stations have each been unique in design following the requirements of the client and the particular mine situation . Other suppliers in the market are going with a more standardised approach . Our clients look for the best possible set-up of the crushing station and they also have specific requirements how they want to operate it . We at FLSmidth are willing and open to work with their needs . If you want to have an adapted hopper design to deal with operational peaks then we can do that ; if you want a special kind of discharge system we can also offer that ; even if you don ’ t want to have advanced sensors and want a basic system then we are OK with that . There are lots of other examples of options but on the whole it has proven very successful for us .”
FLSmidth ’ s IPCC systems also fit with its MissionZero initiative . The company states : “ IPCC systems can be a viable replacement for truck fleets that run on fossil fuels . The positive environmental impact of continuous material transportation on belt conveyors powered with electrical drives can be enormous , with studies showing significant GHG emission reductions . IPCC technology allows for reducing truck haulage in mines by moving the primary crusher from the processing plant closer to the mine for the crushing and conveying of Run-of-Mine ( ROM ) material .”
