Introduction to the ball mill grinding ball

Haoyang ball mill

Haoyang grinding balls are a common medium that is widely used in cement, metal ore, power plants and chemical industries. We are a reliable milling ball manufacturer and supplier in China for more than 15 years. Types of balls are forged steel balls and cast iron balls. Ball mill abrasive balls can provide services to many mining companies around the world, winning the trust of customers with excellent quality and professionalism. We can provide customers with customized abrasives.

In recent years, with the global scale-up of ball mills and the increasing use of large-scale ball mills in mines, there is a great demand for large-diameter wear-resistant steel balls, and the demand is increasing year by year. The main advantage of using large diameter wear-resistant steel balls is that they improve grinding efficiency. The production loss of wear-resistant steel balls is very large, and it is subjected to repeated impacts and material extrusion during the use of the ball mill. Therefore, the failure of macroscopic large-diameter balls is mainly wear, peeling, non-rounding, cracking, etc. In the past, austenitic manganese steel, low alloy steel cast balls, chromium alloy cast iron balls, wear-resistant cast iron and other wear-resistant materials were relatively common in industrial production, but they did not well solve the two contradictions of hardness and toughness, hardenability and alloy element content of grinding balls. Low toughness and high crushing rate; high alloy element content can improve hardenability but increase cost.

Through production practice and continuous testing, we can obtain: Compared with cast balls, the forged steel balls have the main characteristics of fast forging speed, high yield, good shape and smooth surface. The greater the compression of the forged steel ball, the more compact the internal structure of the grinding ball. The forged and polished ball has high hardness, good toughness and is not easy to break. Forged steel balls greatly reduce the use of chromium and reduce environmental pollution, rather than cast balls suitable for use in mines. The forged steel balls using wet grinding are produced by forging residual hot quenching process. The heat treatment process can optimize the structural structure of steel and improve the mechanical properties of steel, which plays a very important role in the normal use of materials.

The forged steel ball has simple production process, low cost, good wear resistance and low crushing rate.

Grinding medium balls forged by Haoyang ball mill are used for crushing during mining or grinding.

The grinding medium is made of steel and cast iron. Manufacturing method. Recently, manufacturers of tamping balls have lost their importance in the market because this method requires a lot of energy, resulting in higher finished product costs. Molding is the second method to produce the finished product for cost. Basically cast iron balls. This type of grinding ball production is also very expensive. In addition to energy consumption, a large part of the “waste” in production will also affect the cost of finished products. At present, the most competitive ball production technology is spiral rolling of round blanks. For energy consumption small enough in production, the amount of "waste" is less than 1-1.5% of the total raw material.
