What is a conical twin screw extruder?

It is a PVC-focused extrusion machine with two tapered, intermeshing screws — wide at the feed end and narrow at the die end. The conical geometry gives high torque and compression in a short length, ideal for PVC pipe, profile, board and WPC.

How does a conical twin screw extruder work?

A forced feeder pushes PVC powder into the wide feed zone; as material moves toward the narrow die end, the shrinking channel compresses, de-aerates and melts it, and a stable pressure pushes a uniform melt through the die to form the product.

Conical or parallel twin screw extruder — which is better?

Neither is universally better. Conical excels at direct PVC pipe, profile and board extrusion thanks to strong feeding and compression. Parallel suits compounding, pelletizing and very high-filler dispersion. Match the machine to your product.

What output can a conical twin screw extruder produce?

It depends on size. A small 45/90 machine runs about 100–180 kg/h, a mid-range 65/132 around 250–380 kg/h, and a large 92/188 machine 600–900 kg/h. Formulation, screw design and downstream capacity also affect real output.

What materials can it process?

Mainly rigid and soft PVC, plus WPC (wood-plastic), PE-based profiles, resin tile and filled/recycled compounds. Its large feed intake makes it especially good at handling low-bulk-density PVC dry-blend powder.

What motor power do I need for PVC pipe?

For general PVC pipe and profile, a 65/132 machine at roughly 37–45 kW is a common choice. Small profiles need 15–22 kW, while large-diameter pipe steps up to 55–160 kW. Size to your target output with headroom.

What are the screw and barrel made of?

Typically 38CrMoAlA nitrided steel, W6Mo5Cr4V2 or HIP powder steel. For abrasive compounds, a tungsten-added bimetallic layer takes the barrel bore to about 62 HRC with a 2.5–3 mm alloy layer for longer wear life.

How do I choose a conical twin screw extruder supplier in China?

Favor a factory that machines its own screws and barrels, provides real specifications in writing, offers nitriding and bimetallic surface options, and states clear lead time, warranty and spare-parts support before you order.

Teb ceev

Lub conical ntxaib ntsia hlau extruder yog PVC-tsim extrusion tshuab nrog ob tapered, intermeshing screws - dav ntawm pub kawg, nqaim ntawm qhov kawg tuag. Lub conical geometry muab siab torque thiab muaj zog compression nyob rau hauv lub compact ntev, ua rau nws tus qauv tshuab rau PVC yeeb nkab, profile, board thiab WPC ntau lawm.

Lub conical ntxaib ntsia hlau extruder yog lub tshuab tom qab feem ntau ntawm lub ntiaj teb rigid-PVC yeeb nkab, profile thiab board. Nws tapered twin-screw tsim daws qhov teeb meem tshwj xeeb: pub lub teeb PVC qhuav-sib tov hmoov thiab compressing nws nyuaj, ceev thiab maj mam txaus kom tsis txhob hlawv ib lub tshav kub-rhiab polymer. Phau ntawv qhia no piav qhia txog yuav ua li cas lub tshuab ua haujlwm, tus qauv qhov ntau thiab tsawg thiab cov khoom tsim tawm kom tau txais, nws piv li cas nrog athaum uas tig mus ntxaib ntsia hlautshuab, thiab yuav ua li cas xaiv qhov zoo - nrog cov ntaub ntawv tshwj xeeb tiag tiag cov neeg yuav khoom xav tau.

Nanhaiya conical ntxaib ntsia hlau extruder teeb rau PVC yeeb nkab thiab profile kab.

Yuav ua li cas lub conical ntxaib ntsia hlau extruder ua haujlwm

Ob lub conical ntsia hlau zaum ib sab ntawm ib sab hauv ib lub thoob sib npaug, meshing nrog ib leeg thaum lawv tig. Cov khoom txav los ntawm qhov loj-inch pub kawg mus rau qhov me me-inch tuag kawg, thiab vim hais tias cov channel ntim shrinks raws txoj kev, cov compound yog compressed, de-aerated, melted thiab homogenized ua ntej nws mus txog qhov tuag. Lub feeder quab yuam thawb lub teeb PVC hmoov rau hauv qhov qhib pub loj kom noj tau nyob ruaj khov.

Lub voj voog muaj plaub theem:

quab yuam pub noj- lub crammer feeder drives qis-bulk-density PVC qhuav-blend rau hauv qhov chaw pub noj dav dav yam tsis muaj kev sib txuas.
Compression & plasticizing- lub taper squeezes cov khoom, tsav tawm cua, thiab melts nws los ntawm kev sib xyaw cua sov thiab shear ntawm qis, tswj kub.
Metering & venting- qhov ruaj khov siab tsim nyob rau hauv qhov nqaim metering cheeb tsam; xaiv lub tshuab nqus tsev vacuum tshem tawm cov dej noo thiab cov volatiles los ntawm cov khoom sib xyaw ua ke.
Tuag tso tseg- Lub cev yaj yog thawb los ntawm qhov tuag los ua cov yeeb nkab, profile, ntawv lossis pellets.

General kev lag luam ceeb toom:conical ntxaib ntsia hlau extruders rau nruj PVC yog feem ntau counter-rotating thiab tag nrho intermeshing - qhov no ua zoo li ib tug zoo-tsav twj tso kua mis, muab tsis tu ncua tso zis ntawm maj shear, uas yog raws nraim li cas tshav kub-sensitive PVC xav tau.

Conical vs parallel ntxaib ntsia hlau extruder

Ob lub tshuab siv ob qhov sib txuas sib txuas, tab sis cov geometry thawb lawv mus rau lwm txoj haujlwm. Raws li txoj cai: xaiv conical rau ncaj qha PVC yeeb nkab / profile / board extrusion, thiab athaum uas tig mus ntxaib ntsia hlautshuab rau compounding, pelletizing thiab high-filler dispersion.

Qhov xwm txheej	Conical ntxaib ntsia hlau extruder	Parallel ntxaib ntsia hlau extruder
Ntsia hlau geometry	Tapered - loj pub, me me tuag kawg	Txoj kab uas hla tsis tu ncua raws qhov ntev
Torque & compression	Siab torque thiab compression nyob rau hauv ib tug luv luv ntev	Ntau qhov compression tas li; ntev L / D rau kev sib xyaw
Pub	Kev noj zaub mov loj - zoo tagnrho rau PVC qhuav-kib hmoov	Txawm tias pub rau pellets thiab tebchaw
Zoo tshaj rau	PVC yeeb nkab, profile, board, ntawv, resin pobzeb	Granulation, masterbatch, WPC compounding, recycling
Filler kam rau ua	Zoo; nce mus rau qhov sib npaug rau CaCO₃ siab heev	Qhov zoo tshaj plaws rau cov khoom ntim siab heev thiab dispersion

Nanhaiya tsim ob qho tib si qauv, yog li lub tshuab tuaj yeem sib phim rau koj cov khoom ntau dua li lwm txoj hauv kev. Ntau cov yeeb nkab thiab profile nroj tsuag khiav conical; compounders thiab WPC pelletizers lean parallel - thiab qee cov nroj tsuag khiav ob qho tib si, sib koom cov kab hauv qab.

Conical ntxaib ntsia hlau extruder qauv & daim ntawv tso zis

Cov zis yog tus naj npawb buyers mob siab rau feem ntau, yog li ntawm no yog qhov loj-rau-tso daim ntawv qhia rau peb conical ntau. Siv nws kom phim cov chav kawm tshuab rau koj lub hom phiaj kab nrawm - tom qab ntawd lees paub qhov tseeb ntawm koj cov khoom.

Qauv	Ntsia hlau txoj kab uas hla	Lub cev muaj zog	Cov zis (kg / h)	Daim ntawv thov tsom
SJSZ-45/90	Φ45/90 hli	15-18.5 kW	100–180 : kuv	Profile me me
SJSZ-51/105	Φ51/105 hli	18.5-22 kWm	150–250 : kuv	Profile, mos PVC
SJSZ-65/132	Φ65/132 hli	37-45 kWm	250–380 : kuv	PVC yeeb nkab / profile
SJSZ-80/156	Φ80/156 hli	55-75 kW	350-500 Nws	Cov kav dej nruab nrab
SJSZ-92/188	Φ92/188 hli	110-160 kWm	600-900 Nws	Cov yeeb nkab loj / extrusion

Raws li kev nyeem nrawm: cov kab ntawv me me feem ntau khiav 45/90 lossis 51/105; dav PVC yeeb nkab thiab profile nyob ib ncig ntawm 65/132; thiab cov yeeb nkab loj loj nce mus txog 80/156 lossis 92/188. Cov zis kuj yog nyob ntawm kev tsim qauv, ntsia hlau tsim thiab lub peev xwm qis, yog li kho cov kab no ua qhov pib.
