Wear-resistant ceramic balls (alumina balls) are now commonly used in two types: 92% and 95%. For some abrasives that are special and require high alumina content, it is recommended to use 95% wear-resistant ceramic balls. To purchase high-quality 95% wear-resistant ceramic balls and alumina balls, please choose Rongsheng Refractory Materials Manufacturer. The products are of high quality and the prices are economical and affordable.
How to Choose High-Quality Wear-Resistant Ceramic Balls?
When purchasing wear-resistant ceramic balls, the product quality of wear-resistant ceramic balls varies, and the prices also vary. Therefore, it is not easy for buyers to buy alumina balls with good quality and reasonable prices.
The important indicators of wear-resistant ceramic balls include wear and content. Many companies can now make wear-resistant ceramic balls with a content of 95%, so this is not a big problem. Then the problem comes. Many purchasers do not have a deep understanding of wear-resistant balls. As long as the content and use of the information obtained meet the requirements, the rest is just price comparison. In fact, this is not the case. The level of wear has a great impact on the price. If you purchase it back just for price reasons, it is very likely that the ball you bought will not meet the standard of wear, and the grinding slag of the wear-resistant ceramic ball will be mixed in, which will affect the quality of the abrasive. Of course, the more obvious result of low wear is that it will not withstand use, thus increasing procurement costs.
The reason for purchasing carefully is to pay attention to cost performance. The main difference between wear-resistant ceramic balls is that the wear is different. The raw materials for the production of wear-resistant ceramic balls are different, resulting in huge differences in their final performance. Everyone in the know understands that the market is divided into three categories: low, medium and high. What’s the difference? Raw materials, formulations and processes. For the same formula and process, the raw materials may be pure alumina powder or a mixture of alumina powder and bauxite. The resulting ball will definitely have different abrasion. The wear-resistant ceramic balls made of pure alumina powder have much lower wear than those mixed with bauxite. Of course, because the price of alumina powder has been rising in recent years, the price of the finished product is also higher than that of ordinary ball stones.
It is recommended that various industries choose different balls according to their own product working conditions. For example, if the hardness of the grinding material is not high and the quality of the product is not very stringent, you can choose ordinary ball stones. For things like metal ores, it’s better to use low-wear ball stones.
How do Alumina Grinding Balls Grind Materials?
Alumina grinding balls are also known as wear-resistant ceramic balls, ceramic balls, porcelain balls, corundum balls, grinding balls, high alumina balls, microcrystalline alumina balls, etc. Alumina grinding balls are made from high-quality alumina powder as raw material, bauxite and roller powder, and are produced through batching, grinding, powdering, molding, drying, calcination and other processes. It can be regarded as a kind of ball stone that has passed the “nine-nine-eighty-one difficulty” and is mainly used as a grinding medium. There are various specifications from 0.5mm to 90mm in diameter, so there is a lot of room for choice.
Generally, alumina grinding balls are used in ball mills. When the ball mill is started, the motor and reducer will transmit torque to the large and small gears. Driven by the large and small gears, the cylinder begins to rotate, and the material is fed into the cylinder from the feed end of the ball mill through the feeder. When the cylinder rotates faster and faster, it will drive the alumina grinding balls and materials in the cylinder to rotate together. Through oxidation, the grinding and throwing force of the grinding ball on the material is used to crush the oxygen material. When the particle size of the material reaches the requirement, it will be discharged through the discharge end.
Although the alumina grinding balls are small, they are high-quality grinding media that are rolled or isostatically pressed and then calcined at high temperatures. High roundness, good wear resistance, large body density, and low wear. It can improve grinding efficiency and reduce usage costs. Contact us to get free samples and quotes.
