Abstract A manufacturing technology has been developed for wear-resistant cast-iron grinding balls without shrinkage defects. In this method, the balls are cast in single-use sand–clay molds. A new approach to designing the casting system is developed. By numerical modeling, the time dependence of solidification is derived. As a trial, grinding balls …
Grinding balls. Grinding balls. Steel and cast iron are the materials used for this type of grinding media. Grinding balls have the following characteristics: Iron, steel, carbide, and ceramic are the materials used for its production; There are quite a few different types of production processes used.
Our steel balls are high– density with impact toughness greater or equal to 7J/cm2. A ball falling 9m during testing reaches greater than or equal to 20,000 times. Actual breakage is less than 0.5%. AUTOMATED PRODUCTION. Our steel balls production process is automated which ensures steel balls have a uniform and stable quality.
We mainly produces forged steel balls, cast iron balls, steel cylpebs, grinding rods, mill liners, steel, hammer heads, automatic production lines for steel balls & grinding rods, decorative wrought iron products and paper-making machinery.
After the primary manufacturing process, every lot of precision steel balls undergoes multiple in-process quality control checks. A visual inspection is performed to check for defects such as rust or dirt. Roller Gauging. Roller gauging is a sorting process that separates both under-size and over-size precision steel balls.
Today, we will introduce the production process of several kinds of grinding ball. The production process of hot rolled steel ball is as follows: 1. Incoming inspection of round steel bars; 2. Ingredients go into the continuous heating furnace heating. 3. The Red Hot billet is rolled into the rolling machine to form a steel ball. 4.
The Difference Between Cast Steel Balls And Forged Steel Balls Aug 13, 2021. In our popular sense, steel balls can be divided into three categories: cast steel balls, forged steel balls, and ductile cast ball grinding balls. But nowadays, nodular cast iron grinding balls are used very rarely, and casting balls and forging are more commonly used.
The automatic ball mill balls casting line is welcomed to produce casting chrome balls from dia30mm to dia150mm.

HX 630 types of ball mill grinding media casting line adopts a 630*630mm metal mold to produce balls.
Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates. Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision. Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
