Ko te whakawehe STET ko te kaiwehe hiko pereti whakarara, Heoi, E hāngai te mau api kawehiko whakapae rite te ātete ki poutū ko te take i roto i te nuinga o ngā whakawehe pereti whakarara rite. I tua atu, te kaiwehe STET oti te tribo-tohutohutia me tuku wā e te nui-tere tuwhera mata nekeneke matūriki. Tēnei āhuatanga e āhei hoki e rua he auau tukatuka motuhake tiketike rawa o te kai, me te ki te āheinga tukatuka nui kaitahi puehu atu pūrere hiko tikanga. The mineral separator machinery has been in commercial operation since 1995 e wehe ana i te waro kāore i te tahuna i te rere kohuke (tata tonu ki te D50 20 μm) i roto i nga hiko waro. This electrostatic separation machine has also been successful at beneficiating other inorganic materials, tae atu ki ngā kohuke pēnei i te konupūmā pākawa waro, talc, barite, me ētahi atu. The STET separator has also been successfully applied to processing agricultural materials such as oilseed meals and pulses, animal meals, and rendering products.
The fundamental details of the STET separator are illustrated below. E whakatupato ana te matūriki i te pānga triboelectric roto collisions matūriki-ki-matūriki i roto i te āputa i waenganui i te electrodes. Te ngaohiko tono i waenganui i te electrodes ko waenganui i ± 4 me ± 10 kV whanaunga ki whenua, hoatu he katoa rerekētanga ngaohiko o 8 - 20 kV puta noa te āputa kawehiko rawa kuiti o kīia ai 1.5 cm (0.6 inihi). E whakaurua matūriki Feed ki te whakawehe STET i tetahi o ngā wāhi e toru (Tauranga whāngai). Ko te whakawehe STET hua e rua anake ngā hua, kohia he awa matūriki tōraro whakatupato i runga i te kawehiko pai whakatupato, ka kohia he awa matūriki pai whakatupato i runga i te kawehiko tōraro whakatupato. The products are conveyed to the respective hoppers at each end of the STET separator by the separator belt, and fall out of the separator by gravity. E kore e te whakawehe STET hua he middlings awa para ranei, ahakoa ki whirihoranga haere maha whakapai ake te viivii hua whakaora me / ranei e taea.
E kawea matūriki i roto i te āputa kawehiko (rohe wehenga) e te koropiko tonu, tuwhera whitiki mata. E whakahaerehia ana te whitiki i te tere tiketike. Ko te āhuahanga o te whitiki kaimahi ki te tahi i matūriki pai atu te mata o te electrodes, preventing the accumulation of fine particles that degrades the performance and voltage field of traditional free fall parallel plate type separation devices. I tua atu, te whitiki mahia he anake tiketike, rohe moveuveu tiketike i waenganui i nga electrodes e rua, whakatairanga tribo-utu. Ko te haere counter-o nāianei o te whitiki whakawehe taea hoki e mea tonu, me te re-e mea ranei matūriki i roto i te whakawehe, te whakakore i te hiahia mō te pūnaha mua tohutohutia-whakarunga o te whakawehe STET. Ko te whakawehe STET ko te auau whāngai tiketike, pūnaha tukatuka arumoni kï. Ko te nuinga te āheinga tukatuka mōrahi o te whakawehe STET he mahi o te auau kai rōrahi e taea te tuku i roto i te āputa kawehiko i te whitiki whakawehe STET. Ētahi atu taurangi, pērā i te tere o te whitiki, te tawhiti i waenganui i te electrodes me te kiato aerated o te paura whai te auau kai mōrahi, nuinga ki te whānuitanga iti. For relatively high density materials, for example fly ash, te auau tukatuka mōrahi o te 42 inihi (106 cm) Ko te pakeke te whanui kawehiko wae wehenga arumoni 40 - 45 Taranata ia haora o te kai. Hoki ngā rauemi kai iti mātotoru, Ko raro te auau kai mōrahi.
| Feed Material | Approximate Compacted Bulk Density | Approximate STET 42 Inch Separator Maximum Feed Rate |
|---|---|---|
| Fly Ash | 60 - 80 pound/ft 3 (1000 –1300 kg/m3) | 40 - 45 Ton per hour |
| talc | 30 - 40 pounds/ft 3 (500 - 600 kg/m3) | 15 - 20 Ton per hour |
| Wheat Flour | 30 - 40 pounds/ft 3 (500 - 600 kg/m3) | 15 - 20 Ton per hour |
The STET separator provides end users with adjustable control of product quality and can be integrated into existing process flowsheets. I tua atu, the STET separator has multiple automation options:
STET currently offers two sizes of the STET separator:
This machine is approximately 9.1 mita (29 waewae, 11 ¾ inches) roa; 1.7 mita(5 waewae, 7 inihi) whānui; 3.2 mita (8 waewae 1 7/8 inihi) tiketike. The compactness of the system allows for flexibility in installation designs and processes up to 40 tonnes per hour for fly ash.
Ko te kohi mana ko e pā ana ki 1 kilowatt-hour per tonne of material processed, with most of the power consumed by the two 50 HP (37 kW) motors that drive the belt.
This machine is approximately 9.1 mita (29 waewae, 11 ¾ inches) roa; 1.2 mita(4 waewae 1 inihi) whānui; 3.2 mita (8 waewae 1 7/8 inihi) tiketike, making it 18” narrower than or 42” model, and is able to process up to 23 feed tons per hour.
Ko te kohi mana ko e pā ana ki 1 kilowatt-hour per tonne of material processed, with most of the power consumed by the two 30 HP (22KW) motors that drive the belt.
