Description
This Casting Grinding Steel Ball is a common grinding medium in mining and cement industry, which can quickly and effectively crush various industrial materials and make them into particles. At the same time, it also helps to grind various materials to make them into fine powders and mix them evenly, especially in the fields of pharmacy and chemistry. This kind of grinding ball is made of cast iron and mass-produced by molds, so it has uniform specifications and can maintain its dimensional accuracy for a long time.
Features
1. Various sizes: The size of our Grinding Steel Balls is optional, ranging from 20-150mm, which is suitable for media selection required by various grinding and abrasive equipment. It will provide users with more flexibility, no matter what materials are used for grinding.
2. Optional hardness: Its raw materials are diverse, with different chromium content, from 1-26%. This makes its surface hardness range from 45-66HRC, which can maintain high stability and avoid damage during grinding.
3. Surface treatment: This Casting Grinding Steel Ball adopts quenching and tempering treatment process, and its surface hardness is increased through heat treatment, so that the production efficiency is improved and the uniform and stable grinding result is maintained.
4. Low breakage rate: The breakage rate is less than 0.5%, which can be used in the field of ball milling of various grinding equipment and seamlessly adapt to different environments and operations. It reduces the downtime and replacement cost, and is convenient for customers to get better economic benefits during use.
Casting Process
The casting process is divided into two main stages: pattern making and casting. In the pattern-making stage, the exact shape and size of the desired ball are created using wax, plastic, or metal patterns. It's important to note that the pattern has to be slightly larger than the ball size because the casting process tends to shrink the pattern. Therefore, the pattern is often coated with a ceramic slurry to create a shell. The ceramic shell is then allowed to dry, and a second coating is applied. The purpose of the ceramic coating is to create a hard and uniform mold that can withstand the intense heat of the molten metal during the casting stage.
In the casting stage, the ceramic shell is heated at high temperatures, and the wax or plastic in the shell melts and pours out, leaving a cavity. Molten metal is then poured into the cavity, filling the space left by the wax or plastic. The metal cools and solidifies, forming a metal ball with the exact shape and size as the original pattern.
Grinding Process
The grinding process is divided into two stages: heat treatment and grinding. In the heat treatment stage, the cast balls are heated to a specific temperature and then quenched in water or oil. This process helps to harden the balls and improve their wear resistance. The balls are then tempered at a lower temperature to improve their toughness and reduce their brittleness.
In the grinding stage, the heat-treated and tempered balls are introduced into a grinding machine where they are ground to the desired size and shape. Grinding machines use abrasive wheels to grind the balls, ensuring that they are round and have a smooth surface. The balls are polished to remove any rough edges and then inspected for quality assurance.
