E lima maina i Europa o lo'o auai i le €7m fa'akomepiuta poloketi
E sefuluono faʻalapotopotoga i totonu o le Iuni a Europa ua tuʻufaʻatasia i le Dig_IT, o se consortium o le a faʻatautaia le € 7-miliona mo se poloketi ua faʻaigoaina A Human-centred Internet of Things Platform for the Sustainable Digital Mine of the Future.
O le sini o le poloketi o le faʻavasegaina o faʻagasologa ma gaioiga i nofoaga eseese o maina i le konetineta, e taʻua o La Parrilla tungsten open-pit mine i Sepania; o le maina maamora i lalo ole eleele a Marini Marmi i Italia; o le Titania ilmenite maina i Nouei; o le maina siliva a Sotkamo i lalo o le eleele i Finelani; ma le Hannukainen eli uamea, kopa ma le auro i Finelani, lea o loo faagasolo le toe tatalaina.
I lalo o le pulega a le Aragón Technological Institute, o sini o le poloketi e tatau ona ausia e ala i le atinaʻeina o se initaneti-o-mea alamanuia tulaga poʻo IIoT e tuʻufaʻatasia ma auʻiliʻili faʻamatalaga mai tagata faigaluega, masini, siosiomaga ma maketi.
"I le fua o tagata, o le faʻavae o le a aoina faʻamatalaga biometric a tagata faigaluega, o latou nofoaga ma tulaga o le siosiomaga i totonu o latou nofoaga faigaluega. I le tulaga o masini, o le a mataʻituina le faʻagaioiga, tulaga, ma le tulaga o meafaigaluega, taʻavale ma meafaigaluega o loʻo faʻaaogaina i le faʻaogaina o le mining.
O le suʻesuʻeina o le siʻosiʻomaga o loʻo siomia ai, o le a faʻamauina tulaga o le siosiomaga, mo se faʻataʻitaʻiga, le lelei o le ea ma le vai, le vevela, faʻapea foʻi ma tulaga o le laufanua, o lona uiga, tulaga o le seismic ma le mautu, "o le faʻamaopoopo o le poloketi María García Camprubí fai mai i se faamatalaga a le aufaasālalau.
E tusa ai ma le tala a García Camprubí, o le meafaigaluega o le a aofia ai faʻamatalaga maketi e pei o faʻamatalaga tuʻuina atu-manaoga ma tau o oloa.
Fai mai le faamaopoopo o le poloketi, e le o se 'tele-faamatalaga' fuafuaga. Ae, o le taulaiga o le a i luga o le tulaga lelei o faʻamaumauga ma latou faʻamatalaga saʻo i le taimi moni e faʻamalieina ai faiga faʻaogaina ma faʻagaioiga. Ina ia ausia lenei faʻamoemoe, o le a faʻalagolago le consortium i tekinolosi faʻatekinolosi, faʻataʻitaʻiga o faʻamaumauga, faʻataʻitaʻiga faʻagasologa, faʻatupuina o masaga numera, fesoʻotaʻiga ma le atinaʻeina o masini.
Fai mai García Camprubí o le a tuʻuina atu le faʻamamafa faʻapitoa i le fausiaina o masaga numera e faʻatautaia ai meafaigaluega faʻapitoa mo le tausiga, le mautu o le eleele, ma le lelei o le ea ma le vai.
E ui lava o vaega taʻitasi o le a faʻatalanoaina e se faʻalapotopotoga eseese, o faʻataʻitaʻiga e maua mai o le a faʻatautaia ma Caelia Twinkle, o se masini fau masaga numera mo le taimi moni faʻainisinia fesoasoani komepiuta, lea o le a mafai ai ona tuʻufaʻatasia masaga numera i totonu o le IIoT platform taʻitasi.
Polo Mill Liner Mea Filifilia
Eseese mea nutimomoia, tulaga faigaluega eseese e manaomia liners mea eseese e fetaui. E le gata i lea, e mana'omia e le vaega e olo ai ma'ale'ale ma mea e olo lelei ai.
H&G Machinery ma le tele o tagata gaosi oloa fa'atau. e tu'uina atu mea nei e lafo ai lau ili polo:
Uamea Manganese
O le manganese o loʻo i totonu o le paʻu uʻamea uʻamea uʻamea maualuga manganese e masani ona 11-14%, ma o le carbon content e masani lava 0.90-1.50%, o le tele o ia mea e sili atu i le 1.0%. I uta maualalo a'afiaga, o le maaa e mafai ona o'o i le HB300-400. I le maualuga o aʻafiaga o uta, o le maʻaʻa e mafai ona oʻo i le HB500-800. Faʻalagolago i le mamafa o le aʻafiaga, o le loloto o le faʻamaʻaʻaina e mafai ona oʻo i le 10-20mm. O le mea fa'ama'a'a ma le ma'a'a maualuga e mafai ona tete'eina le a'afiaga ma fa'aitiitia le ofuina abrasive. O le uʻamea maualuga o le manganese o loʻo i ai le lelei tele o le faʻaogaina o le faʻaogaina i lalo o le tulaga o le malosi o le aʻafiaga o le ofuina o le abrasive, o lea e masani ona faʻaaogaina i vaega faʻafefeteina o le mining, mea faufale, mana vevela, ma isi masini masini. I lalo o tulaga o tulaga maualalo aʻafiaga, maualuga manganese sila e le mafai ona faʻaaogaina uiga o meafaitino ona o le faʻamalosia o galuega e le o manino.
