What Are the Advantages of Ceramic Grinding Balls?
Ceramic grinding balls are a kind of grinding media used in a series of equipment such as ball mills, vibration mills, and jar mills for fine grinding. But do you really know ceramic grinding balls? Today, Naike Chemical will introduce this ceramic grinding ball to you.
Advantages of ceramic grinding ball
Quality and size: The range of ceramic grinding balls with various sizes from 0.5mm to 60mm and alumina purity range from 92% to 99.5% provides multiple choices to meet the grinding requirements.
The small crystal size of ceramic grinding balls continuously media and even small wear.
Time-saving: The high density and perfect roundness provide greater grinding efficiency, thus saving time.
Cost-saving: High impact strength and wear resistance reduce replacement costs.
With the advantages of high hardness, large volume density, corrosion resistance, and others, the grinding efficiency and wear resistance of ceramic grinding balls are much better than those of ordinary stones or natural pebbles, especially for the precise grinding and cutting of hard and thick materials in ceramics, glass, enamel, paint, and chemical plants.
Ceramic grinding balls are an important engineering ceramic and belong to high-tech products. Due to their suitable hardness, moderate density, wear resistance, corrosion resistance, low cost, and the problem of metallic impurities introduced by metal balls, ceramic grinding balls are widely used in raw material grinding and processing in industries such as white cement, mineral, ceramics, electronic materials, magnetic materials, coatings, paints, etc. They are high-quality grinding media. In the ceramic industry, the wear efficiency of ceramic grinding balls is higher than that of natural flint and pebble.
With the decrease of high-quality natural stone resources and the high wear rate of ordinary porcelain balls, ceramic grinding balls will be used more and more by ceramic manufacturers. According to different alumina contents, they can be divided into medium alumina ball, medium-high alumina ball, and high alumina ball. Generally, we call those with 60%-65% alumina content medium alumina ball, those with 75%-80% alumina content medium-high alumina ball, and those with over 90% alumina content high alumina ball.
Among them, high alumina balls are further divided into 90 ceramics, 92 ceramics, 95 ceramics, and 99 ceramics. 99 ceramics are rarely mass-produced by major manufacturers due to their high production costs and are mainly handmade by some special ceramic factories. With good quality, high efficiency, time-saving, and cost-saving, ceramic grinding balls fully comply with the industrial production philosophy, which is the reason why they can survive in this market and better meet the industrial production demand.
Production and wear of ceramic grinding ball
There are three ways to produce ceramic grinding balls. The first one is to drop them from a high altitude to contact with the raw materials in the reaction to different degrees of impact, which is very suitable for being in contact with other ball-shaped substances and can fully exert their functions. The second way is sliding. After the friction between the ceramic balls, powdery materials can be produced. The third way is rolling, using the force of the machine to promote the rolling of ceramic balls and promote the occurrence of the reaction. There are mainly two types of wear, the first one is macroscopic wear, which can be seen by the naked eye, and the wear process causing the disappearance of ceramic grinding balls is caused by fracture. The second type is microscopic wear, which is caused by plastic deformation and is difficult to observe. It can have a long service life, and ceramic grinding balls belong to the second type.
