[ 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
Economical Bolt-On Replacement
Ni-Hard delivers the abrasion and corrosion resistance a mixing paddle needs at a cost that suits a part on a regular renewal cycle. Bolt-on mounting means no welding - blades change out fast during routine maintenance.
Profile That Protects Mix Quality
A correct leading-edge profile and tight liner clearance keep cycle times short and the batch homogeneous. Renewing blades before the edge rounds off guards against the under-mixing that quietly erodes concrete strength.
Economy or Long-Life Grade
Choose economical Ni-Hard for a part on a regular renewal cycle, or high-chromium iron for longer life under harder aggregate - matched to your output rather than a single stock grade.
Mixer blades do the actual work of the machine: bolted to the arms, they fold, lift and shear the aggregate, cement and water into a homogeneous batch on every revolution. The blade profile and its clearance to the liner set how fast and how evenly the plant mixes.
As the leading edge rounds off and clearance widens, mixing slows - cycle times stretch, batches finish unevenly or segregated, and the plant burns more energy to reach the same result. Concrete that leaves the mixer under-mixed shows up later as inconsistent strength, the kind of quality problem that is hard to trace back to a worn paddle. Renewing blades on schedule is the cheapest way to protect both throughput and batch consistency.
Sureay supplies bolt-on blades cast in Ni-Hard iron above HB 600 - a deliberately economical, abrasion- and corrosion-resistant choice for a part that is replaced on a regular cycle. They drop onto the existing arms of Sicoma, Liebherr, MEKA, Simem, SANY, Zoomlion, Teka, BHS and Eirich plants, and typically run 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
01How often should concrete mixer blades be replaced?+−
As a rule of thumb, every 6-18 months - high-output plants running abrasive aggregate sit at the shorter end. Rather than wait for a fixed date, watch for longer cycle times, uneven batches or a visibly rounded leading edge and widened liner clearance; these are the signs the blade is no longer mixing efficiently.
02Are bolt-on mixer blades better than welded blades?+−
For most plants, yes. Bolt-on blades change out in minutes without welding, hot work permits or grinding, so maintenance is faster and safer, and the arm underneath is not heat-affected by repeated welding. Our Ni-Hard blades are designed as bolt-on replacements for the listed OEM mixers.
03Which concrete mixers do your blades and paddles fit?+−
Bolt-on blades are supplied for twin-shaft and planetary mixers from Sicoma, Liebherr, MEKA, Simem, SANY, Zoomlion, Teka, BHS and Eirich. We match the blade profile and bolt holes to your arms; blades for other plants can be copied from a worn sample.
04What is the difference between Ni-Hard and high-chrome mixer blades?+−
Ni-Hard is an economical, abrasion- and corrosion-resistant grade well suited to a paddle renewed on a regular cycle. High-chromium iron carries a higher carbide volume for longer life under harder, more abrasive aggregate. We match the grade to your output and aggregate hardness.
05Can you supply concrete mixer blades to a sample or drawing?+−
Yes - send a worn blade, a sketch with dimensions or the plant model and we cast bolt-on replacements that drop onto your existing arms. OEM/ODM work is welcome, including non-standard profiles and bolt patterns.
06Why is my concrete mixing slowly or unevenly?+−
As the blade leading edge rounds off and clearance to the liner widens, mixing slows and batches finish unevenly or segregated. Renewing blades before the edge wears back keeps cycle times short and protects batch consistency - under-mixed concrete shows up later as inconsistent strength.
07What is the minimum order quantity and lead time for mixer blades?+−
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.
