Ke Koʻikoʻi o ke Kaʻina Hana Wela no ka Pressure Roller o ka Mīkini ʻĀpana

ʻO ka mīkini pellet kahi mea hana no ka hoʻopili ʻana i ka wahie pellet biomass a me ka hānai pellet, ʻo ia hoʻi ka wili kaomi kona ʻāpana nui a me ka ʻāpana palupalu. Ma muli o kāna ukana hana kaumaha a me nā kūlana hana koʻikoʻi, ʻoiai me ke ʻano kiʻekiʻe, ʻaʻole hiki ke pale ʻia ka ʻaʻahu a me ka haehae. I ke kaʻina hana, kiʻekiʻe ka hoʻohana ʻana i nā wili kaomi, no laila he mea nui loa ka mea hana a me ke kaʻina hana o nā wili kaomi.

Ka nānā ʻana i ka hemahema o ka wili kaomi o ka mīkini ʻāpana

ʻO ke kaʻina hana o ka wili kaomi e komo pū ana me: ka ʻoki ʻana, ka forging, ka normalizing (annealing), ka mīkini ʻino, ka quenching a me ka tempering, ka mīkini semi precision, ka quenching surface, a me ka mīkini precision. Ua hana kahi hui loea i kahi noiʻi hoʻokolohua e pili ana i ka hoʻohana ʻana i nā wahie pellet biomass no ka hana ʻana a me ka hana ʻana, e hāʻawi ana i kahi kumu kumumanaʻo no ke koho kūpono o nā mea wili a me nā kaʻina hana wela. Eia nā hopena noiʻi a me nā ʻōlelo paipai:

ʻIke ʻia nā ʻūpā a me nā ʻōpala ma luna o ka ʻili o ka lola kaomi o ka granulator. Ma muli o ke komo ʻana o nā mea haumia paʻakikī e like me ke one a me nā waihona hao ma ka lola kaomi, pili ia i ka ʻaʻahu kūpono ʻole. ʻO ka awelika o ka ʻili ma kahi o 3mm, a ʻokoʻa ke ʻano o ka ʻaʻahu ma nā ʻaoʻao ʻelua. He ʻaʻahu koʻikoʻi ka ʻaoʻao hānai, me ka ʻaʻahu o 4.2mm. ʻO ke kumu nui o ka mea ma hope o ka hānai ʻana, ʻaʻole i loaʻa i ka homogenizer ka manawa e hoʻolaha like i ka mea a komo i ke kaʻina hana extrusion.

Hōʻike ka loiloi hāʻule ʻana o ka ʻaʻahu microscopic ma muli o ke ʻaʻahu axial ma luna o ka ʻili o ka wili kaomi i hoʻokumu ʻia e nā mea maka, ʻo ka nele o nā mea ʻili ma luna o ka wili kaomi ke kumu nui o ka hāʻule ʻana. ʻO nā ʻano nui o ke komo ʻana, ʻo ia ka ʻaʻahu pipili a me ke ʻaʻahu abrasive, me ke ʻano e like me nā lua paʻakikī, nā kualono palau, nā ʻauwaha palau, a me nā mea ʻē aʻe, e hōʻike ana he ʻaʻahu koʻikoʻi nā silicates, nā ʻāpana one, nā waihona hao, a me nā mea ʻē aʻe i loko o nā mea maka ma luna o ka wili kaomi. Ma muli o ka hana a ka mahu wai a me nā kumu ʻē aʻe, ʻike ʻia nā ʻano lepo e like me ka lepo ma luna o ka wili kaomi, e hopena ana i nā māwae corrosion stress ma luna o ka wili kaomi.

Manaʻo ʻia e hoʻohui i kahi kaʻina hana wehe haumia ma mua o ka wāwahi ʻana i nā mea maka e wehe i nā ʻāpana one, nā waihona hao, a me nā mea haumia ʻē aʻe i hui pū ʻia i loko o nā mea maka, i mea e pale ai i ka ʻaʻahu ʻino a me ka haehae ʻana ma nā wili kaomi. E hoʻololi i ke ʻano a i ʻole ke kūlana hoʻonohonoho o ka scraper e hoʻolaha like i ka mea i loko o ke keʻena compression, e pale ai i ka ikaika like ʻole ma ka wili kaomi a hoʻonui i ka ʻaʻahu ma ka ʻili o ka wili kaomi. Ma muli o ka hāʻule nui ʻana o ka wili kaomi ma muli o ka ʻaʻahu ʻili, i mea e hoʻomaikaʻi ai i kona paʻakikī kiʻekiʻe o ka ʻili, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa ʻana i ka palaho, pono e koho ʻia nā mea kūpaʻa ʻaʻahu a me nā kaʻina hana wela kūpono.
