[ Grade Selection ]
Choosing the Right Grade
This is a hard-iron wear face (HB 600+). The right grade depends on your aggregate and output — harder, more abrasive aggregate justifies a higher-carbide grade:

Engineering Advantages
W-Type Contour Reach
The W profile follows the floor and lower-wall contours that a straight scraper skips, clearing hot mix from the corners where carbon build-up otherwise starts and spreads.
Resettable Hot Clearance
An adjustable mount lets operators hold and reset the floor clearance as the scraper wears - the practical control that keeps discharge clean and the chamber free of baked-on deposits.
HB600+ High-Chrome at Temperature
Cast in high-chromium iron above HB 600, the W-profile edge resists sharp aggregate at mixing temperature, holding a clean floor clearance that keeps the chamber free of baked-on carbon.
The W-type scraper works the floor and lower walls of the pugmill, sweeping hot mix toward the discharge gate so the chamber empties cleanly at the end of each batch. Its W profile reaches the contours an ordinary straight scraper leaves behind.
Let the scraper wear and clearance open up, and hot mix is left to cling, cool and carbonize on the chamber surfaces. That baked-on build-up reduces effective batch volume, can break loose and contaminate later batches, and eventually has to be burned or chipped out during a forced shutdown. A scraper held to its clearance keeps discharge clean and the chamber free of carbon deposits.
Sureay W-type scrapers are cast in high-chromium iron above HB 600 for abrasion resistance at mixing temperature, on adjustable mounts so clearance can be reset as they wear. They fit pugmill and twin-shaft plants from Ammann, Marini, Benninghoven, MEKA and Astec, with a typical 6-18 month service life depending on output and aggregate hardness.
[ How to Order ]
Made to fit your plant — from a sample or a model
Every part is cast to order. There is no catalogue number to look up — we reverse-engineer the fit from your worn part or plant model, so you get an exact replacement rather than a near-miss.
Send your part or model
Email a photo of the worn part, its key dimensions, or your plant make and model. If you can ship the worn part it becomes the master pattern for an exact copy.
We measure & match
Our team reverse-engineers the geometry, bolt pattern and profile, and recommends the grade for your aggregate, output and temperature.
Confirm the quote
You approve dimensions, grade, price, MOQ and lead time before anything is cast — no surprises.
Cast, inspect & ship
We cast on our lost-foam / DISA lines, run a dimensional and hardness check, and ship factory-direct to 50+ countries. A material and hardness report can travel with the order.

Product FAQs & Buying Guidance
Technical FAQs
01What causes carbon build-up in an asphalt pugmill?+−
Hot mix left on the floor and walls after discharge cools and carbonizes layer by layer. The usual root cause is a worn scraper or opened-up clearance that no longer clears the chamber. A W-type scraper held to its set clearance sweeps the surfaces clean each cycle and stops deposits forming.
02How often should asphalt mixer scrapers be replaced?+−
Plan on 6-18 months depending on output and aggregate hardness, and reset clearance regularly in between. A scraper run past its adjustment range leaves residue to carbonize and wears the liner behind it, so renewing on schedule protects neighbouring parts as well as discharge quality.
03Which asphalt mixing plants do your scrapers fit?+−
W-type scrapers are supplied for pugmill and twin-shaft plants from Ammann, Marini, Benninghoven, MEKA and Astec, plus generic pugmills. We match the profile and mount to your mixer; scrapers for other plants can be copied from a worn sample.
04What is a W3-type asphalt scraper and how is it different?+−
The W3 profile is a three-lobe contour that follows the pugmill floor and lower-wall corners a straight scraper skips, clearing hot mix from exactly the spots where carbon build-up starts. Other W-profiles and custom shapes are available to suit your chamber.
05Can the asphalt scraper clearance be reset as it wears?+−
Yes. Scrapers sit on an adjustable mount so floor clearance can be held and reset over the part's life. Keeping clearance tight is what sweeps the chamber clean each cycle; a scraper run past its adjustment range leaves residue to carbonize and wears the liner behind it.
06What material are asphalt mixer scrapers made of?+−
Scrapers are cast in high-chromium iron above HB 600 for abrasion resistance at hot-mix temperature, with a precision-finished edge so they hold a clean, repeatable floor clearance.
Why Choose Sureay
01Is Sureay a direct manufacturer or a trading company?+−
We are a direct factory. Most mixer wear parts are cast and machined in-house on our lost-foam and DISA green-sand lines, while sealing components are precision-molded - either way you deal with the people who actually make the parts and skip the trading-company markup.
02Can you supply parts to fit a specific OEM mixer model?+−
Yes. Send the plant make and model, or a photo and key dimensions of the worn part, and we match the casting and bolt pattern. We supply OEM-fit replacement wear parts for the major concrete and asphalt plant brands and welcome OEM/ODM work.
03Are you ISO certified and do you ship internationally?+−
Sureay is ISO 9001:2015 certified and ships factory-direct to over 50 countries. Each order can include a material and hardness report on request.
