Concrete Mixer Arm 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 Arm
The mixing arm of the concrete mixer is one of the components. The mixing arm itself is divided into side mixing arms (positive and negative) and middle mixing arms (also positive and negative). Below the mixing arm is a connected tile base, which is connected to the mixing arm. Use 4 sets of high-strength bolts for the mixing arm. Above is the installed wear-resistant mixing blade, and 2 sets of high-strength bolts are used to connect the mixing blade.

According to the utility model, the side arm is moved back in the rotation direction of the overall mixing arm layout, so that it lags behind the end arm of the mixing arm group on the same side. In this way, during actual operation, the side arm has less working resistance and is in contact with the mixing drum. There is no cutting and grinding between them, which improves the durability of the side arms and reduces the driving force required for the mixing shaft. Therefore, a low-power motor can be installed, which reduces manufacturing costs and energy consumption accordingly. Cast iron material has high strength and good wear resistance.
How to use concrete mixer mixing arm?
Mixing middle arm
This piece is installed on the large shaft in the mixer barrel and is clamped with the lower seat. The upper part is equipped with an intermediate mixing blade. The large shaft is responsible for the mixing of materials during production and operation.
Therefore, the production quality requirements for the middle mixing arm are relatively high. It bears the mixing load of the mixer blades, has a long wear-resistant life, and has corresponding willfulness. The mixing arm is the core accessory in the entire mixer barrel, collectively referred to as “safety parts”. During use, if this part of the accessory breaks, it will cause mechanical failure and bring immeasurable economic losses to the manufacturer.
Side mixing arm (left and right)
This accessory is installed at both ends of the mixing barrel. The lower part is clamped with the base of the mixer accessory on the large shaft. The upper part is equipped with side mixing blades, and the middle part is equipped with a side scraper.
During operation, the material in the upper part must be stirred and rubbed with the end plate liner to prevent the material from sticking to the liner in the barrel, thereby extending the service life of the liner.

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
