Square ceramic liners yog precision-txiav los ntawm high-density alumina (feem ntau 92% los yog 95% Al₂O₃) thiab sintered rau huab hardness (HRA 85-90). Lawv cov geometry tiaj tus tso cai rau gapless, pobzeb-rau-pobzeb tso, ua kom muaj kev tiv thaiv ntau tshaj plaws thaum txo tus naj npawb ntawm kev txiav. Muab piv rau cov vuas puag ncig lossis hexagonal, cov squares tau nrawm dua rau kev teeb tsa thiab yooj yim dua los hloov hauv thaj chaw, ua rau lawv nyiam xaiv rau cov ntawv ntim siab, nruab nrab ntawm cov ntawv thov.
Kev Pabcuam Kev Ua Haujlwm & Kev Tiv Thaiv Hnav
Square liners npog ze li ntawm 100% ntawm qhov chaw tiaj tus thaum pw kom raug, tsuas yog nyias nyias, ncaj seams. Round vuas, los ntawm qhov sib txawv, tawm ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Hexagonal vuas muab kev pabcuam zoo tab sis xav tau kev txiav ntau dua thiab kev sib tw nruj dua.
Cov ntaub ntawv point:Hauv 10 m² chute, square vuas (150 × 150 mm) npog 98.5% ntawm thaj chaw nrog cov qauv 3 hli grout kab. Round vuas ntawm tib txoj kab uas hla tsuas yog 78% - qhov seem 22% yuav tsum tau sau los yog yuav erode sai.
Installation ceev & nqi zog
Square liners yog qhov ceev tshaj plaws rau nruab. Tsis xav tau kev hloov pauv lossis ntsuas ntsuas - cov neeg ua haujlwm tsuas yog tso rau hauv kab. Hexagonal vuas xav tau kev sib dhos angular; cov pobzeb puag ncig yuav tsum tau ua tib zoo sib nrug kom tsis txhob muaj kab ntau dhau.
Kev lag luam siv:ASTM C704 (kev kuaj coj los tiv thaiv) tsis qhia meej cov duab, tab sis cov kev tshawb fawb hauv teb qhia tau tias cov neeg coob ntawm ob tuaj yeem nruab 40 m² ntawm square liners rau ib qho kev hloov pauv piv rau 25 m² ntawm hexagons thiab 18 m² ntawm rounds.
Impact Resistance & Shape Limitations
Cov vuas square muaj cov npoo ncaj, uas tuaj yeem ua qhov tsis muaj zog hauv qhov cuam tshuam loj heev. Cracks feem ntau pib ntawm cov ces kaum. Hexagonal thiab puag ncig cov duab faib cuam tshuam kev ntxhov siab ntau dua vim tias lawv tsis muaj 90℃fab. Rau thaj chaw muaj kev cuam tshuam loj (piv txwv li, crusher tawm chutes nrog 50 kg pob zeb ntog 2 m), pom zoo kom pom cov duab nruj dua los yog cov kab sib xyaw ua ke (nrog cov roj hmab rov qab) yog pom zoo.
Cov ntaub ntawv point:Standard 92% square vuas (tsis muaj thaub qab) qhia ntug chipping tom qab 3 lub hlis nyob rau hauv thawj crusher chute. Hexagonal vuas ntawm tib qib xeem dhau 8 lub hlis. Txawm li cas los xij, cov vuas square nrog 5 hli roj hmab interlayer ua tiav 12 lub hlis - ntev dua ob qho tib si.
Lub Sijhawm Saib Xyuas Lub Sijhawm Ntev & Hloov Tus Nqi
Thaum ib lub pobzeb pobzeb tawg, nws tuaj yeem raug tshem tawm thiab hloov pauv yam tsis muaj kev cuam tshuam cov vuas nyob ib sab - muab cov nplaum nplaum tsis dhau nruj. Hexagonal thiab round vuas feem ntau kaw ua ke nruj dua, ua rau qhov chaw hloov nyuaj.
Piv txwv li:Ib qho chaw cog qoob loo hauv West Virginia siv square 95% alumina liners nyob rau hauv qhov hnyav-media cyclone feed chute. Tom qab 42 lub hlis ntawm kev ua haujlwm, tsuas yog 7% ntawm cov vuas yuav tsum tau hloov. Cov nroj tsuag tau txuag tau $ 18,000 hauv kev ua haujlwm thiab zam peb lub sijhawm kaw cia piv rau lawv cov txheej txheem puag ncig yav dhau los.
Txhawb cov ntsiab lus ntawm cov ntaub ntawv (tuaj yeem nthuav tawm raws li lub rooj ceev hauv kab lus tseeb):
| Cov duab | Kev pab them nqi (%) | Nruab nrawm (m² / ua haujlwm) | Impact resistance (kwv yees) | Yooj yim kho qhov chaw |
|---|---|---|---|---|
| Square | 98.5 | 40 | Nruab nrab (zoo heev nrog roj hmab thaub qab) | Siab |
| Hexagonal | 95 | 25 | Siab | Nruab nrab |
| Hloov | 78 | 18 | Siab | Tsawg |
Case Study (luv luv, raws li tau thov):
Daim ntawv thov:Limestone hloov chute ntawm cov cement cog hauv Kentucky.
Previous tsab xov xwm:80 hli puag ncig alumina vuas - ua tsis tiav tom qab 9 lub hlis vim slurry nkag los ntawm crescent khoob.
Kev daws:150 × 150 × 25 mm square 92% alumina vuas nrog interlocking ntug tsim (tab sis tsis tag nrho staggered, cov seams ncaj nraim tau nqaim).
Qhov tshwm sim:Lub square liner tau siv sijhawm ntev li 27 lub hlis - peb zaug ntev dua cov pobzeb puag ncig - thiab tshem tawm ob qhov kev kaw ib xyoos. Tus neeg ua haujlwm cog tau tshaj tawm txog 40% txo qis hauv cov nqi txhua xyoo.
