Create a sustainable future
As mining casting manufacturers, Balasen can undertake various mining machinery industry components, not limited to crushing equipment castings (such as jaw plates, hammer heads, liners, etc.), crushing equipment castings (such as ball mill barrels, ball mill end caps, grinding discs, etc.), and conveying equipment castings (such as scrapers, chain plates, rollers, etc.).
The materials include:
High manganese steel, such as ZGMn13;
High chromium alloy;
Carbon steel, such as Q235C ZG45, ZG35;
Wear resistant cast iron, alloy steel, etc.
High Wear Resistance:
In the operation of mining machinery, castings frequently come into contact and rub against materials such as ores. Components like the jaw plates of crushers and the liners of ball mills require materials with high wear resistance to extend their service life, reduce maintenance costs, and minimize downtime. Furan resin sand casting is often preferred for such components due to its excellent surface finish and wear resistance properties.
Sufficient Strength and Toughness:
Castings such as the boom and the arm of an excavator must endure heavy impact forces and loads. This requires materials with sufficient strength and toughness to prevent fractures or deformation, ensuring safe and reliable operation. Certain custom sand castings are specifically engineered to meet these demanding structural requirements.
Good Corrosion Resistance:
Mining environments often involve corrosive substances such as humid air and acidic or alkaline ores, which can degrade castings. Materials with good corrosion resistance are essential—especially in wet beneficiation systems—to maintain long-term performance. Processes like lost foam casting can be beneficial in achieving precise, corrosion-resistant parts for such conditions.
Good High-temperature Resistance:
Some mining machinery operates in high-temperature environments, such as rotary kilns. This requires the casting materials to maintain stable mechanical properties at high temperatures, have good thermal fatigue resistance and oxidation resistance, and prevent problems such as softening and deformation due to high temperatures.
Good Machinability:
In order to facilitate the processing of castings into components that meet the requirements, the materials should have good machinability, including cuttability and weldability. This can reduce the processing difficulty, improve production efficiency, and ensure the processing quality.
Excellent Work-hardening Property:
High-manganese steel castings have the property of work-hardening. When subjected to impact and friction, the surface hardness can be rapidly increased, which significantly enhances the wear-resistance. This makes them suitable for components that are strongly impacted, such as the jaw plates of jaw-crushers.
Good Toughness:
They possess good toughness and can withstand large-impact loads without being prone to fracture. This ensures the long-term and stable operation of mining machinery under harsh working conditions.
Good Castability:
High-manganese steel castings have good castability, which makes it easy to form components with complex shapes, thus meeting the structural requirements of different components of mining machinery.
