ʻO ka mea kanu hui pahu hoʻomau he ʻoihana hui ʻoihana e hana ana i ka hui ʻana o ka asphalt ma ke ʻano pahu pahu mau, hiki ke hoʻokaʻawale ʻia kēia mea kanu i nā mea kanu asphalt drum mix a me nā mea kanu hoʻohuihui asphalt. Hana ʻia kēia mau hale hana ʻelua i ka asphalt mix wela i ka hana mau. ʻO ka hoʻomehana ʻana, ka maloʻo a me ka hui ʻana o nā ʻano mea kanu asphalt ʻelua e lawe ʻia i loko o ka pahu.

Hoʻohana pinepine ʻia nā mea kanu hui pahu mau (drum Mix Plant a me nā mea kanu hui pū ʻana) i ka hana ʻenekinia, ka wai a me ka mana, ke awa, ka uapo, ke ala nui, ke alahao, ke kahua mokulele, a me ke kūkulu ʻana i ke alahaka, a me nā mea ʻē aʻe. Loaʻa iā ia kahi ʻōnaehana hoʻohui anu, ʻōnaehana hoʻoheheʻe, kahi ʻōnaehana maloʻo, kahi ʻōnaehana hui, kahi ʻohi lepo wai, kahi ʻōnaehana asphalt, a me kahi ʻōnaehana uila.



ʻO nā mea like o nā mea kanu asphalt pahu a me nā mea kanu asphalt counter flow
ʻO ka hoʻouka ʻana i nā hōʻuluʻulu anuanu i loko o nā pahu hānai ʻo ia ka hana mua i ka hana ʻo Asphalt Drum Mix Plant. ʻO ka mea maʻamau he ʻekolu a ʻehā paha mea hānai bin (a ʻoi aku paha), a hoʻokomo ʻia nā hōʻuluʻulu i loko o nā pahu like ʻole e pili ana i ka nui. Hana ʻia kēia no ka helu ʻana i nā ʻāpana like ʻole e like me nā koi o ka papahana. Loaʻa i kēlā me kēia keʻena kahi puka hoʻoneʻe no ka mālama ʻana i ke kahe o nā mea. Aia ma lalo o nā pahu kahi kāʻei conveyor lōʻihi e lawe i nā aggregates i ka pale scalping.

ʻO ke kaʻina hana kānana e hiki mai ana. Hoʻopau kēia pale vibrating deck hoʻokahi i nā hōʻuluʻulu nui a mālama iā lākou mai ke komo ʻana i ka pahu.

He mea koʻikoʻi ka conveyor charging i ke kaʻina hana asphalt no ka mea ʻaʻole ia e lawe wale i nā ʻāpana anuanu mai lalo o ka pale a i ka pahu akā ke kaupaona pū kekahi i nā aggregates. Loaʻa i kēia conveyor kahi pahu ukana e hoʻokipa mau i nā aggregates a hāʻawi i kahi hōʻailona i ka papa mana.

ʻO ka pahu hoʻomaloʻo a me ka hui ʻana e mālama i nā hana ʻelua: ka maloʻo a me ka hui ʻana. Ke kaʻa mau nei kēia pahu, a hoʻoili ʻia nā aggregates mai kekahi ʻaoʻao a i kekahi i ka wā o ke kipi. Hoʻohana ʻia ka wela mai ka lapalapa ahi i nā mea hōʻuluʻulu e hōʻemi i ka ʻoluʻolu.

ʻO ka pahu pahu pahu pahu hoʻomaloʻo a hāʻawi i ka wahie i ka pahu pahu. Ma waho aʻe o kēlā, ʻo ka mea nui i loko o nā pahu mālama asphalt e mālama ai, wela, a me ka paila e pono ai ka asphalt i ka pahu maloʻo no ka hui ʻana me nā mea wela. Hoʻohui nā silos hoʻopiha i ka mea hoʻopihapiha koho a me nā mea hoʻopili i ka mea hui.

Pono nā ʻenehana hoʻomalu haumia i ka hana. Kōkua lākou i ka wehe ʻana i nā kinoea weliweli mai ke kaiapuni. ʻO ka mea hōʻiliʻili lepo mua, he ʻohi lepo maloʻo ia e hana like ana me ka ʻohi lepo lua, hiki ke lilo i kānana ʻeke a i ʻole kahi holoi lepo pulu.

ʻOhi ka mea lawe ukana i waho i ka asphalt hui pū wela mai lalo o ka pahu a lawe aku i ke kaʻa kali a i ʻole ka silo mālama. Mālama ʻia ka HMA i kahi silo mālama koho a hiki i ke kaʻa.


Nā ʻokoʻa o nā mea kanu asphalt pahu a me nā mea kanu asphalt counter flow
1. Pono ka pahu i ka hana Asphalt Drum Mix Plant. I loko o kahi mea kanu kahe like, neʻe aku nā hui mai ka lapalapa ahi, akā, i loko o kahi mea kanu counterflow, neʻe nā aggregates i ka lapalapa ahi. Hoʻohui ʻia nā ʻāpana wela me ka bitumen a me nā minela ma kekahi ʻaoʻao o ka pahu.

2. Ua like ke kahe o ka huina i loko o ka mea kanu like me ka lapalapa ahi. Hōʻike pū kēia i ka neʻe ʻana o nā mea hōʻuluʻulu mai ka lapalapa ahi i ko lākou hele ʻana. He kū'ē (kū'ē) ke kahe ʻana o nā ʻāhuehue i ka lapalapa ahi, no laila ke neʻe nei nā ʻili i ka lapalapa ahi ma mua o ka hui ʻana me ka bitumen a me nā minerale ʻē aʻe. He mea maʻalahi kēia, akā he hopena koʻikoʻi ia i ke kaʻina hana o kēia mau ʻano hui asphalt a pili pū i ka maikaʻi o ka HMA. Manaʻo ʻia ʻo ka hui counter-flow e mālama i ka ʻaila hou a hāʻawi i ka HMA ʻoi aʻe ma mua o ka mea ʻē aʻe.

ʻO ka papa hoʻomalu ma nā mea hana o kēia mau lā he mea hou a paʻakikī. Hāʻawi lākou i ka mālama ʻana i nā ʻano hui like ʻole e pili ana i ka makemake o ka mea kūʻai. Hiki ke mālama ʻia ka mea kanu mai kahi wahi hoʻokahi ma o ka papa hoʻomalu.
