[ 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
Precise, Resettable Wall Clearance
A ground edge profile on an adjustable mount lets operators hold a tight wall clearance and reset it as the scraper wears - the single factor that keeps the drum discharging clean instead of glazing over with hardened residue.
HB600+ High-Chrome Edge
Cast in high-chromium iron above HB 600, the ground edge holds its profile against abrasive aggregate, so wall clearance stays tight for longer between resets.
Protects the Liner Behind It
A scraper renewed on schedule keeps discharge clean and stops residue glazing the drum - run past its adjustment range it wears its own mount and the liner it rides against.
The scraper rides closest to the drum wall and floor, sweeping the last of the concrete toward the discharge gate and keeping the chamber surfaces clean between batches. It is the part that decides whether a mixer empties completely or leaves a skin of material behind.
When the scraper edge wears back and the wall clearance opens up, residue is left to harden on the drum. That build-up steals batch volume, throws the mixing action out of balance, and eventually has to be chipped out by hand - lost production on top of an avoidable cleaning job. A scraper held to its set clearance keeps discharge clean and the rated batch size intact.
Sureay scrapers are cast in high-chromium iron above HB 600 and finished to a precise edge profile, with an adjustable mount so wall clearance can be reset as the part wears. They fit twin-shaft and planetary plants from Sicoma, Liebherr, MEKA, Simem, SANY, Zoomlion, Teka, BHS and Eirich, and typically last 6-18 months. Service life depends on output, aggregate hardness and duty cycle — verify against your OEM service interval.
[ 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
01Why is my concrete mixer leaving residue after discharge?+−
The most common cause is a worn scraper or an opened-up wall clearance: once the edge no longer reaches the drum surface, a film of concrete is left to harden each cycle. Renewing the scraper and resetting clearance restores clean discharge and recovers the batch volume lost to build-up.
02How long does a concrete mixer scraper last?+−
Typically 6-18 months. Service life depends on throughput and aggregate hardness, and on how often clearance is reset - a scraper run past its adjustment range wears its mount and the liner behind it, so renewing on schedule protects neighbouring parts too.
03Which concrete mixing plants do your scrapers fit?+−
Our concrete scrapers fit twin-shaft and planetary plants from Sicoma, Liebherr, MEKA, Simem, SANY, Zoomlion, Teka, BHS and Eirich. We match the mount and edge profile to your mixer; scrapers for other brands can be reproduced from a worn part or drawing.
04What material is a concrete mixer scraper made of?+−
Scrapers are cast in high-chromium iron above HB 600, hard enough to hold a clean edge against abrasive aggregate while sweeping the drum wall and floor. The edge is precision-ground so the scraper sits to a tight, repeatable wall clearance.
05How do I set and adjust the concrete scraper clearance?+−
The scraper sits on an adjustable mount, so the edge can be set close to the drum wall and reset as it wears. Holding a tight clearance is what keeps the drum discharging clean; a scraper run past its adjustment range leaves residue and wears the liner behind it.
06Why is my concrete mixer not discharging fully?+−
Incomplete discharge is usually a worn scraper or an opened-up wall clearance that leaves a film of concrete to harden each cycle. Renewing the scraper and resetting clearance restores clean discharge and recovers the batch volume lost to build-up.
07What is the minimum order quantity and lead time for scrapers?+−
We ship factory-direct and keep the MOQ low on replacement wear parts; exact quantity and lead time depend on the model and whether tooling already exists. Send your plant model for a quote - most repeat items ship in a few weeks, and a material and hardness report can be included on request.
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.
