Product Details


The arm is one of the main components of the vertical grinding mill, consisting mainly of the upper arm, lower arm, arm shaft, bearings, and bearing bases. Its function is to transfer the pressure of the hydraulic cylinder to the grinding roller, converting it into a grinding force on the material bed. This force is transmitted to the lower arm, then to the upper arm, and finally to the grinding roller through a pin shaft connected to the lower arm.

Articulated Arm Production Process

The upper and lower arms are connected by a conical pin, making them an integrated unit. The central shaft is connected to both arms via expansion sleeves, which are used to secure the arms and shaft, aligning concentrically. The cone sleeve is inserted into the connecting holes of the upper and lower arms, featuring cuts. When the cone pin is pressed into the cone sleeve with a cover, the sleeve expands tightly onto the arm.


Arm casting steel material

Xinxiang Great Wall is a large-scale domestic foundry production base, utilizing optimized alloy steel with a chemical match of ZG270-500 and ZG30SiMnMo in its arm jib production, ensuring excellent wear resistance and strong resistance to fracturing.

Articulated Arm Structure Advantages

1. Good wear resistance and less prone to breakage.

2. Utilizes arc gouging and shot blasting processes to ensure surface quality.

3. Level 2 flaw detection, ensuring quality.

4. Prior to shipment, our company's professional inspectors will conduct multiple non-destructive inspections on the arm's load-bearing surface to ensure the elimination of defective products.

Xinxiang Great Wall Advantages

1. Possess a foundry base in the northern region of Henan Province

2. Equipped with professional level II flaw detection equipment

3. Imported from Russia: 6625Y龙门镗铣床 (2.5m x 8.0m)

4. Heavy-duty CNC universal roller bending machines, 120×3000, made in China

5. Precision finishing of cast steel components is achieved through processes such as arc gas cutting, CO2 gas shielded welding, and shot blasting.

6. Castings can weigh up to 150 tons, and we can design matching casting processes based on the structure and technical standards of the cast steel components.
