Concrete Mixer Liner SANY brand JS3000 for concrete mixing plant and concrete mixer spare part
The concrete mixing arm is made of Wear-Resistant Alloy Steel and its wear resistance is enhanced through heat treatment process. The split assembly structure makes it convenient to replace the wear-resistant sleeve. It is widely used in large-scale projects such as high-speed railways and Bridges, and is suitable for the mixing of dry-hard and plastic concrete.

Description of Mixing Liner
During the mixing process of aggregates in a mixer, the abrasive action of sand and gravel on the drum wall leads to significant wear. To reduce damage to the drum wall, it is necessary to incorporate lining plates inside. Typically, high-chromium cast iron lining plates are used in mixers. Since these lining plates are thin-walled castings, generally below 20mm, it becomes challenging to enhance hardness through heat treatment when the area/thickness ratio is high. Otherwise, the lining plates are prone to deformation, affecting their usability.

How to use concrete mixer wear part liner?
End plate liner
This piece can be divided into several pieces and spliced together according to the capacity of the mixer barrel, mainly to ensure that the end face of the barrel is not worn.
Wear-resistant arc liner
This piece is installed on the overall lining plate in the mixing barrel. It can be divided into several pieces for easy installation. It mainly protects the barrel from being worn by materials.
Throat liner (Long strip plate)
This component is installed on both sides of the discharge opening, in close contact with the discharge opening plate, to prevent leakage of materials and slurry.

FAQ
Q
How to choose the right model of concrete mixer according to my construction project?
A
Q
What types of mixer accessories does your company mainly produce?
A
We focus on producing the core wear-resistant parts of the JS series forced concrete mixers, including:
Mixing arm (double spiral belt/spiral blade type)
High chromium alloy liner (bottom plate/side plate)
Hydraulic seal shaft end assembly (including floating oil seal)
Wear-resistant alloy blades (spiral angle can be customized)
Wear-resistant guard plate for mixing tank
Q
How to ensure the wear resistance of the accessory material?
A
Triple strengthening process is adopted:
① Material upgrade: Liner/blade uses Cr20Mo2 high chromium alloy with a hardness of HRC58-62; shaft end uses QT600 ductile iron
② Structural optimization: The hyperbolic design of the mixing arm reduces material impact loss
③ Process guarantee: EPC lost foam casting
Q
How to confirm that the accessories match my equipment model?
A
Please provide any of the following information, and we will provide free adaptation verification:
✓ Host brand and model (such as: Sany JS2000, Zoomlion JS3000)
✓ Original accessories part number
✓ Measurement of key dimensions
