The consumable cost of mining enterprises accounts is the largest proportion of the total cost of mines, how to reduce the cost of mine consumption has always been an issue in the entire mine field. Ceramic balls have been used as grinding media in fine grinding for many years. They are mainly used in high-speed rotary fine grinding equipment, such as ISA grinding, Smith VXP grinding, Metso SMD grinding, etc. These devices are characterized by high speed between media. The speed difference formed by the motion produces a grinding action to grind the material. The vertical spiral agitating mill mainly relies on the low-speed rotation of the spiral agitator to drive the pressing force and shearing force generated by the grinding media to grind the material. The density of the media is one of the main factors affecting the grinding effect.
High-chromium steel ball is a traditional grinding medium for vertical mixing grinding in mining industry, it has high hardness and good wear resistance. Ordinary ceramic balls are lighter in density and have a lower hardness. With the advancement of wear-resistant materials technology, a new type of nano-ceramic ball based on alumina or zirconia has emerged in recent years. Chemshun Ceramics can produce ceramic grinding media with new type of nano-ceramic balls with alumina and zirconia material.
Collect below advantage of ceramic grinding media for your reference:
1. Energy saving
Under the same grinding process conditions, the quantity of ceramic grinding media is large, but the total mass is small, and the energy saving effect is very obvious.
2. Reduce the consumption of produced media
Through calculation, the yield of medium-produced medium steel ball is 0.68~0.11 kg/t, while the consumption of ceramic grinding media is 0.052～0.063 kg/t, which is calculated by the price of ceramic ball 35 000RMB/t and high chromium forging ball 7 800RMB/t. After changing to ceramic balls, the cost of production per unit of production can be reduced by about 65%.
3. Prolong the service life of spiral liner
After replacing with ceramic ball media, the life of the vertical mill spiral liner will increase.
4. Shorten single inspection time
The ceramic ball has uniform hardness inside and outside, and it is always in a spherical state after wear, and the surface is smooth. However, due to its uneven hardness, the steel ball has irregular polygonal bodies after wear, which determines that the ceramic ball is more easily discharged from the volleyball, which can effectively shorten Volleyball time. After the grinding door is opened, due to the light density of the ceramic ball, the labor intensity of manually removing the remaining sphere at the bottom is lower than that of the steel ball.
5. Reduce iron impurity pollution
For most non-metallic minerals, the impurity content, especially iron, determines the quality grade of the product. Many non-metal grinding processes are used to reduce iron impurities, and iron removal is usually carried out during processing. If ceramic grinding media is used in the fine grinding stage, the iron impurity contamination can be effectively reduced.
Ceramic grinding media is your best choice for mining industry, to meet the market requirement of different milling applications, QMX Ceramics developed a range of ceramic grinding media with broadest range of sizes and densities are available to suit both horizontal and vertically mills for fine &ultra-fine grinding, mix and dispersing.
