[ 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
Hot-Mix Abrasion Resistance
High-chromium iron above HB 600 stands up to sharp mineral aggregate at mixing temperature, giving a sacrificial wear face that protects the structural mixer shell from both abrasion and heat.
Flush, Sealed Segments
Accurate green-sand casting keeps each plate flush so hot mix cannot pack behind the liner, where trapped, hardened material would pry plates loose and shorten the life of the whole set.
Shields the Structural Shell
The liner is the sacrificial barrier that takes hot-mix abrasion and heat so the mixer shell never does. Replacing before it thins through keeps the repair at liner cost, not shell cost.
Liner plates protect the inside of the pugmill from the twin assault of hot, sticky bituminous mix and the sharp mineral aggregate carried in it. They are the barrier that keeps abrasion and heat off the structural mixer shell.
When a liner wears thin or a bolt backs out, hot mix works its way to the shell and to the gap behind the plate, where it packs, hardens and accelerates the next failure. Left too long, the damage moves from a cheap liner swap to a shell repair and extended downtime in the middle of a paving season - the worst possible time to lose a plant.
Sureay asphalt liners are cast in high-chromium iron above HB 600, selected to hold up to abrasion at mixing temperature, and produced on the lost-foam and DISA green-sand lines for accurate, flush-fitting segments. They bolt into pugmill and twin-shaft plants from Ammann, Marini, Benninghoven, MEKA and Astec, with a typical 6-18 month service life depending on throughput 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 asphalt plant liner plates to fail early?+−
Usually it is mix packing behind a plate through a worn bolt or an uneven seam: trapped hot mix hardens, lifts the plate and exposes the shell. Flush-fitting plates and routine bolt checks prevent it. Replacing before a liner thins through keeps the repair at liner cost rather than shell cost.
02Can the same liner plates be used for concrete and asphalt mixers?+−
The material family is similar - high-chromium iron above HB 600 - but the profiles and fixings differ by plant, and asphalt service adds sustained heat. We supply liners matched to your specific asphalt plant model rather than a generic plate, so fit and sealing are correct.
03Which asphalt mixing plants do your liner plates fit?+−
Liner plates are supplied for pugmill and twin-shaft plants from Ammann, Marini, Benninghoven, MEKA and Astec, plus generic pugmills. We match the plate profile, thickness and bolt layout to your mixer; plates for other plants can be reproduced from a worn sample.
04How long do asphalt pugmill liner plates last?+−
Typically 6-18 months, depending on output and aggregate hardness. Watch the remaining plate thickness and the fixing bolts - replacing before a liner thins through keeps hot mix off the structural shell, which is far costlier to repair than a liner swap.
05Can you supply asphalt liner plates in custom sizes?+−
Yes. Liner plates are made to your pugmill's dimensions, including non-standard thicknesses and bolt patterns, and matched to your aggregate hardness. Send a worn plate or a dimensioned drawing and we cast a matching set.
06How are asphalt liner plates fixed inside the mixer?+−
Liner plates bolt to the mixer shell and sit flush against each neighbour so hot mix cannot pack behind them. Renew the fixing bolts with the plates - a backed-out bolt lets hot mix work behind the liner, where it hardens and pries plates loose.
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.
