What is a conical twin screw barrel?

It is a tapered twin-bore extrusion component in which two conical screws rotate inside a matching conical barrel. The taper compresses and plasticizes material over a short length, making the conical screw barrel ideal for PVC pipe, profile, sheet and WPC extrusion.

What materials is it best used for?

Rigid PVC (pipe, profile, board and sheet), wood-plastic composite, PE-based profiles and resin tile, plus PVC pelletizing. It handles low-bulk-density dry-blend powders especially well thanks to its large feed-end intake.

How is it different from a parallel twin screw barrel?

A conical barrel tapers and builds high compression with gentle shear, suiting direct PVC/WPC extrusion. A parallel twin screw barrel keeps a constant diameter and higher shear, which suits compounding, masterbatch and very high-filler formulations.

What is the typical clearance between screw and barrel?

Clearance is the small gap between the flight tip and the bore wall. It is set tight and accurate on a new part; as it opens up from wear, output and pressure drop. Measuring it periodically is the clearest way to track barrel wear.

How do I install a conical twin screw barrel?

Power down and lock out, clean the mating faces, mount and align so the screws turn freely, wire each heater zone and thermocouple correctly, then bring the barrel up to temperature slowly and soak it before starting the screws.

What causes wear in conical twin screw barrels?

Mainly abrasive fillers such as calcium carbonate, wood fiber and glass, made worse by corrosion from PVC processing, poor maintenance and under-specified hardness. A deeper bimetallic or tungsten-carbide layer resists all three far better.

How often should the barrel be inspected or replaced?

Do visual and purge checks monthly and measure clearance quarterly. Replacement timing depends on filler load and run hours — track the wear trend rather than waiting for a failure, and rebuild or replace once clearance moves past spec.

How do I choose the right size for my extrusion line?

Match the diameter ratio and length to your extruder model and target output, then pick a surface treatment based on how abrasive your formulation is. Send a drawing or a sample with key dimensions so the barrel is an exact fit, not an approximation.

Pehea ka hana ʻana o ka pahu pahu māhoe conical

Ma kahimāhoe conical screw extruder, noho ʻelua ʻaoʻao ma kahi ʻaoʻao ma kahi kihi liʻiliʻi, ākea ma ka hopena hānai a haiki i ka hopena make. Hoʻopili ka pahu i ka liʻiliʻi e kūlike. Ke neʻe nei ka mea maka mai ka ʻāpana hānai anana nui a i ka ʻāpana anana anana liʻiliʻi, hoʻopaʻa a hoʻopaʻa ʻia ka nui o ka emi ʻana i ka wā e lawe a hui pū nā mokulele intermeshing. Ma muli o ka hoʻohuli ʻana o nā wili ʻelua a pili pono, ʻo ka māhoe conical wili a me ka barela e like me ka pauma hoʻoneʻe maikaʻi - hoʻopuka paʻa i ka ʻoki haʻahaʻa haʻahaʻa, e pale ana i nā polymers wela e like me PVC.

Hoʻokaʻawale ke kaʻina hana i ʻekolu mau pae:

Hānai a lawe- ʻO ke anawaena hoʻopau hānai nui e hāʻawi i ka nui o ka lawe ʻana, no laila ua huki ʻia ka hui ʻana o ka pauka a me nā mea haʻahaʻa haʻahaʻa (e like me ka PVC dry-blend) me ka hilinaʻi ʻole.

Ka ana a me ka hoʻokuʻu ʻana- kūkulu ka ʻāpana ana haiki i ke kaomi paʻa a hoʻokuʻu i ka hoʻoheheʻe like ʻole a homogeneous ma o ka make ma kahi kaohi.

ʻOi aku ka hana o ka barela ma mua o ka mālama ʻana i nā wili. Lawe ʻo ia i nā ʻāpana wela a me nā mea hoʻoluʻu e paʻa i kēlā me kēia pae i ka mahana kūpono. Hoʻohana ʻo Nanhaiya barela i kahi hoʻolālā hoʻomehana a me ka hoʻolālā hoʻoluʻu - maʻamau ka hānai ʻana, ka hoʻopiʻi ʻana a me nā ʻāpana homogenization - me ka hoʻokuʻu ʻana i ka momi no ka huki ʻana i ka makū a me nā volatiles mai ka heheʻe, he mea nui ia no nā pūhui piha a hygroscopic.
