What is a parallel twin screw barrel?

It is a twin-bore barrel holding two constant-diameter intermeshing screws that run side by side. Unlike a conical barrel, the screws stay the same size end to end and the system is usually segmented, so the screw profile can be reconfigured for different formulations.

What is the difference between co-rotating and counter-rotating?

Co-rotating screws turn the same way and give high-shear mixing at high speed — ideal for compounding and masterbatch. Counter-rotating screws turn oppositely with gentler, pump-like conveying — better for PVC and heat-sensitive, high-filler work.

What is a segment (building-block) parallel twin screw barrel?

It is a modular design where the barrel is bolt-together sections and the screw is keyed elements on a shaft. You can position feed, mixing, vent and metering sections as the recipe needs, and replace only the worn segment instead of the whole screw.

Parallel or conical twin screw barrel — which do I need?

Choose conical for direct PVC pipe, profile, board and sheet extrusion. Choose parallel for granulation, compounding, masterbatch and very high-filler or glass-fibre dispersion, where reconfigurable mixing matters most.

What is a parallel twin screw barrel used for?

Mainly granulation and pelletizing, compounding and masterbatch, PS foaming, aluminum-plastic composite panel, rubber and plastic, and parallel-layout PVC lines. The tunable screw profile lets one machine handle many recipes.

Should a parallel barrel be nitrided or bimetallic?

Clean compounds can run nitrided. Abrasive recipes — high mineral filler, glass fibre, high carbonate — should be bimetallic; a tungsten-added alloy reaching 62 HRC resists that abrasion far longer than a thin nitrided case.

What is a parallel twin screw extruder?

It is the machine that houses a parallel twin screw and barrel, typically co-rotating for compounding and pelletizing. The barrel and screw are the wear heart of the machine and are matched to the extruder and the recipe.

How do I order the right parallel twin screw barrel?

Jawaab degdeg ah

Barmiil mataano ah oo isbarbar socda ayaa leh laba boolal oo isdhexgal ah oo dhexroor joogto ah oo is garab socda Si ka duwan sida foosto koonka ah, boolaluhu waxay ahaanayaan isla cabbirka dhammaadka ilaa dhammaadka, foosto badanaa waxaa laga dhisay qaybo. Boolal isbarbar socda oo is-beddelaya waxay ku habboon yihiin isku-darka, granulation iyo masterbatch; boolal isbarbar yaacaya oo rogan ayaa ku habboon PVC iyo shaqada buuxinta sare.

Thebarmiil mataano isku mid ahwaa faras-shaqeedka isku-darka iyo pelletizing - meel kasta oo aad uga baahan tahay isku-darka degdegga ah, xakamaynta heerkulka saxda ah iyo dabacsanaanta dib-u-habeynta furaha qaab cusub. Meesha foosto conical ah loo dhisay si toos ah PVC extrusion, foosto isbarbar yaac ah ayaa loo dhisay si ay u noqoto mid kala duwan. Hagahan waxa uu sharxayaa sida ay u shaqeyso, farqiga muhiimka ah ee u dhexeeya isku-wareejinta iyo nashqadaha rogaal celiska ah, qaybta (dhismaha-block) qaabdhismeedka ka dhigaya mid dabacsan, iyo sida loo doorto midka saxda ah ee alaabtaada.

Parallel twin screw barrel (counter-rotating) manufactured by Nanhaiya — Furo mataano ah oo isbarbar socda iyo foosto - dhexroor joogta ah ayaa ku dhex xirta foosto mataano ah oo isbarbar socda.

Waa maxay barmiil mataano ah oo isbarbar socda?

Barmiil isbarbar yaac ah ayaa haysa laba boolal oo dhexroor isku mid ah laga bilaabo quudinta ilaa dareeraha, oo ku dhex orda jaan-siddeed mataano ah. Sababtoo ah dhexroorku waa mid joogto ah, habdhaqanka farsamaynta waxaa dejinaya furahahabayntahalkii aad ka isticmaali lahayd taper - waxaad ku beddeshaa waxqabadka adiga oo bedelaya walxaha furaha, ma beddeleyso qaabka foosto. Taasi waa sababta isku-dhafka mataanaha iyo nidaamyada foostada ay u badan yihiin isku-darka: isla mashiinka ayaa socodsiin kara cuntooyin aad u kala duwan iyadoo dib loo dhisayo furka.

Laba shay ayaa qeexaya barmiil mataano ah oo isbar-bar socda: jihada boolalku u leexdaan (isku-wareejin ama wareeg-wareejin), iyo sida foosto iyo furka loo dhisay (badanaa laga soo bilaabo qaybo). Labaduba hoos bay ku daboolan yihiin. Farsamoyaqaannada hoose, arag sharraxaaddayadasida isbarbar yaabka mataanaha u shaqeeyo.

Isku-wareejin vs-rogid-rogid

Tani waa farqiga ugu muhiimsan ee qoyska isku midka ah. Labaduba waa naqshado mataano ah oo isku dhafan, laakiin si aad u kala duwan ayay u gudbiyaan oo way isku daraan.

Qodob	Isbarbar yaaca wada-wareegga ah	Isbarbar-dhigga ka-hortagga
Wareegid wareeg	Labada boolalba isku si bay u leexdaan	Isbuunyadu waxay u leexdaan jihooyin iska soo horjeeda
Isku qas	Xirmo-xiirid sare leh, qaybin aad u wanaagsan & isku darka kala firdhiyey	Debecsanaan, kalnder u eg, gudbinta togan
Xawaaraha caadiga ah	Xawaaraha isbiirtada oo sarreeya, wax soo saar sare	Xawaaraha hoose, cadaadiska joogtada ah ayaa dhismaya
ugu wanagsan	Isku-darka, Duubista Master-ka, granulation, Buuxsan/dharado-fibre	Dhuumaha/profile-ka PVC, kulaylka xasaasiga ah, PVC-buuxiyaha sare
Dareen	Dib loo habeyn karo "mashiinka isku dhafka ah"	Bambo u eg, jilicsan "mashiinka saarista"

Marka la soo koobo: isku dhafka mataanaha ah ee isku-wareegaya waa qalabka isku dhafka iyo kala firdhinta; fur mataano rogan oo rogaal celis ah ayaa ah aaladda gudbinta PVC deggan ee dabacsan. Dhir badan baa leh labadaba. Haddii shaqadaadu u beddesho maaddooyinka pellets, waxaad rabtaa inaad isku beddesho; Haddii ay u rogayso PVC-isku-darka-engegan ee tubada ama profile,-rogid-rogid (ama foosto koonical) ayaa ku habboon.

Qaybta (dhismaha-block) naqshadaynta foosto

Inta badan nidaamyada isbarbar yaaca waa modular: foostadu waxay ka samaysan tahay qaybo isku xidhan iyo furaha walxaha furaha ah oo lagu dunsan yahay shafka. Habkan "dhismaha-block" waa waxa siinaya foosto isku midka ah ee mataanaha ah ee dabacsanaanteeda - waxaad dhigi kartaa qayb quudin, qaybo kala duwan oo isku dhafan, hawo-mareen iyo qaybta cabbirka sida saxda ah ee ay u baahan yihiin cunto karinta, oo aad ku beddesho walxaha xiran ama aan ku habboonayn si gaar ah halkii aad ka beddeli lahayd furaha oo dhan.

Faa'iidooyinka la taaban karo:

Dib loo habayn karo- Dib-u-dhis profile-ka furaha si loo habeeyo cusub oo aan lahayn mishiin cusub.
Qaybaha xidhashada la beegsaday- Beddel oo kaliya qaybta xiran, ha beddelin daboolka iyo foosto oo dhan.
Ku neefsashada meesha aad u baahan tahay- qaybaha hawo-mareenka ee qoyaanka iyo ka saarista kacsan.
Isku qas xoojinta baahida- ku dar ama ka saar baloogyada cajiinka si aad u hagaajiso xiirta.

Barmiil vs conical twin screw foosto

Iibsadayaasha inta badan waxay miisaamayaan barbar-dhig afoosto fur mataano ah. Xeerka gaaban: conical for extrusion tooska ah ee PVC, isku midka ah isku dhafka iyo dalbanaya isku-dhafka.

Maaddada iyo daaweynta dusha sare

Isku-darku waa shaqo xoqan - fiber galaas ah, buuxinta macdanta iyo karbohaydraytyada sare waxay xidhaan boolal iyo fuustooyin si degdeg ah - sidaas awgeed daawaynta maadada iyo dusha sare ayaa ah mid aad ugu badan nidaamka isbarbardhigga sida kan kooniska ah. Nanhaiya waxay dhistaa boolal iyo fuustooyin isbarbar socda oo ah 38CrMoAlA nitrided steel, W6Mo5Cr4V2 ama HIP bir budada ah, oo leh nitrided, bimetallic ama tungsten-carbide sagxadaha si ay ugu dhigmaan nabarka cuntadaada.

Iskudhisyada aadka loo buuxiyey ama muraayadaha lagu xoojiyay, dusha bimetallic ayaa ah doorashada macquulka ah: daawaynta tungsten-ka lagu daray ayaa gaadhaysa62 HRCgudaha godka - oo ka soo horjeeda 58 HRC oo caadi ah - nolol adeeg oo dheer. Fuustooyinka barbar socda ayaa loo haystaa dulqaad dhan ±0.01 mm. Haddii aad miisaamayso xulashooyinka dusha sare, eeg hagahayagafuustooyin bimetallic ah, kaas oo si siman u quseeya nidaamyada isbarbar-dhigga ah.

Sida loo doorto foosto mataano ah oo isku mid ah oo sax ah

Afar su'aalood ayaa ku siinaysa qeexitaanka saxda ah:

Wada- ama rogaal celis?Isku-darka iyo jeexjeexin → wada-wareejin; PVC iyo gudbin dabacsan → rogaal celis ah.
Maxaad qabanaysaa?Cuntadani waxay dejisaa astaanta furka - isku-darka blocks ee kala firidhsan, hawo-mareenada kacsan.
Sidee bay u xoqan tahayBuuxiyaha sare ama fiber galaas → bimetallic / tungsten-carbide dusha sare.
Mashiinkee?U soo dir summadaada/qaabka ama sawir-qaadka si qaybaha iyo shafka ay si sax ah u waafaqaan.

Boolal iyo fuustooyin isbarbar socda ayaa si wax ku ool ah u caado u ah mashiinka iyo cuntada, markaa sawir ama muunad lagu daray alaabtaada iyo wax soo saarkaaga ayaa noo ogolaanaya inaan soo xigano mid ku habboonkali ah, barmiil isbar-bar-bar-bar-soceed ah ama mid toosan - ama dhammaystiranmishiinka extruder- 12 saacadood gudahood.

Su'aalaha soo noqnoqda

Waa maxay barmiil mataano ah oo isbarbar socda?

Waa foosto mataano ah oo sita laba dalool oo is-dhex-dhexaad ah oo joogto ah oo is barbar socda. Si ka duwan foostada koonka ah, boolaluhu waxay joogayaan isla cabbirka dhamaadka ilaa dhamaadka nidaamkana inta badan waa la kala qaybiyaa, sidaa darteed astaanta furaha waxaa dib loogu habeyn karaa qaabab kala duwan.

Waa maxay farqiga u dhexeeya isku-wareejin iyo wareeg-wareejin?

Iskoollada isku-wareegaya waxay isu beddelaan si isku mid ah waxayna siinayaan isku-darka-xiirid sare leh xawaare sare - ku habboon isku-darka iyo masterbatch. Muraayado-wareega-rogid-rogid ah ayaa si liddi ku ah u leexanaya si dabacsan, gudbinta bamka u eg-waxay u fiican yihiin PVC iyo kuleyl-xasaasi, shaqo-buuxiyaha sare.

Waa maxay qaybta (dhismaha-block) barmiil mataano ah oo isbarbar socda?

Waa naqshad qaabaysan halka foostada ay ka kooban tahay qaybo isku xidhan oo furuhu ay yihiin walxo furaha usheeda dhexe ku yaal. Waxaad meel dhigi kartaa quudinta, isku dhafka, hawo-mareenka iyo qaybaha cabbirka sida cuntada loo kariyo, waxaadna bedeli kartaa oo keliya qaybta xiran halkii aad ka isticmaali lahayd furaha oo dhan.

Barmiil mataano ah oo isbar-bar socda ama mid toosan - kee baan u baahanahay?

Dooro conical si toos ah tubada PVC, profile, looxa iyo extrusion xaashida. Dooro isbarbar-dhigga granulation, isku-darka, masterbatch iyo firidhsan aad u sarreeya ama fibre-glaas, halkaas oo arrimaha dib-u-habaynta dib-u-habayntu ay muhiim u tahay.
