ST Equipment & Technology LLC (STET) azụlitewo a akwụkwọ, patented electrostatic belt separator nke e gosiri na azụmahịa-ọnụ ọgụgụ na nhazi nke ulo oru minerals na imegharị ihe maka iji nke coal combustion ada uyi.
Electrostatic nkewa technology a mụwo n'elu 100 afọ. N'ezie, mbụ patented nri ojiji nke electrostatic nkewa nke wheat middlings gbara akwụkwọ na 1880. Na-aga n'ihu research na technology na-egosi nkwa na-eke uru site n'efu stream byproducts nke ugbu a mmepụta Filiks, dị ka osisi mmanụ mmepụta ma ọ bụ anụmanụ (tinyere azụ) nhazi.
nanị tinye, na STET separator ọrụ dabere na iche iche na n'elu onwu. Mgbe ụfọdụ, ndị a nkewa gaghị ekwe omume iji urughuru size ma ọ bụ njupụta naanị. STET si separators-uru nke "Tribo-Nchaji" (Lee Ọgụgụ 1) nke pụtara ngwa ngwa n'ime ngwá.
Ọgụgụ 2 na-egosi otú ahụ na-nri site na otu n'ime ọtụtụ iri nri ọdụ ụgbọ mmiri n'ime nkewa mpaghara, nke bụ ọdịiche dị n'etiti kwụ electrodes (< 13mm [0.5"]). voltaji (a 12kV) na-etinyere gafee a warara ọdịiche ike a siri ike electric ubi. Ahụ na-kpaliri site na nke a nkewa mpaghara site a proprietary aga n'ihu loop, emeghe ntupu belt na-arụ ọrụ na elu na-agba (4-20m / s [13-65ft / s]).
N'ime nkewa mpaghara, na proprietary imewe nke ngwa ngwa na-akpụ akpụ na-aga n'ihu belt anamde ọtụtụ ọrụ n'out oge (Ọgụgụ 3).
Ọ na-emepụta a elu ịgbā mpaghara n'etiti electrodes, akwalite tribo-Nchaji. Nke a na-esite ugboro ugboro urughuru-to-urughuru collisions, edebe ihe ebubo n'ime separator na iwepu mkpa maka mpụga tupu odori usoro. Egbu, ije nke belt sweeps iwu ahụ si electrodes, ịnọgide na-enwe ha arụmọrụ, na mmemmem iche iche ngwaahịa na site-ngwaahịa collection.
The STET tribo-electrostatic belt separator gosiri ike "beneficiate" (melite Njirimara nke) a dịgasị iche iche nke mineral na ofufe ash gburugburu ụwa na egosiwo ngwa maka nhazi nke a na-eto eto ọnụ ọgụgụ nke nri na oriri ihe.
Otu ihe atụ nke a bụ na nhazi nke Whitefish Nri nke e commercially nwetara, milled, na-anwale site na anyị pilot-ọnụ ọgụgụ separator nọchiri na Ọgụgụ 4.
