Advantage of Ceramic Grinding Media for Mining Business
The consumable cost of mining enterprises accounts is the largest proportion of the total value of mines, methods to reduce the price of mine consumption has always been an issue in your complete mine field. Ceramic balls have been used as grinding media in fine grinding for a lot of years. They are primarily utilized in high-pace rotary fine grinding equipment, resembling ISA grinding, Smith VXP grinding, Metso SMD grinding, etc. These units are characterized by high pace between media. The pace distinction formed by the motion produces a grinding motion to grind the material. The vertical spiral agitating mill primarily relies on the low-pace rotation of the spiral agitator to drive the urgent power and shearing pressure generated by the grinding media to grind the material. The density of the media is likely one of the most important factors affecting the grinding effect.
High-chromium steel ball is a traditional grinding medium for vertical mixing grinding in mining trade, 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 supplies technology, a new type of nano-ceramic ball primarily based on alumina or zirconia has emerged in current years.
Gather beneath advantage of ceramic grinding media for your reference:
1. Energy saving
Under the same grinding process conditions, the quantity of ceramic grinding media is giant, but the total mass is small, and the energy saving impact could be very obvious.
2. Reduce the consumption of produced media
Via calculation, the yield of medium-produced medium steel ball is 0.sixty eight~0.11 kg/t, while the consumption of ceramic grinding media is 0.052～0.063 kg/t, which is calculated by the value of ceramic ball 35 000RMB/t and high chromium forging ball 7 800RMB/t. After altering to ceramic balls, the price of production per unit of production will be reduced by about 65%.
3. Prolong the service lifetime 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, because of its uneven hardness, the metal ball has irregular polygonal bodies after wear, which determines that the ceramic ball is more easily discharged from the volleyball, which can successfully shorten Volleyball time. After the grinding door is opened, because of the light density of the ceramic ball, the labor intensity of manually removing the remaining sphere at the backside is decrease than that of the steel ball.
5. Reduce iron impurity air pollution
For many non-metallic minerals, the impurity content, particularly 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 might be effectively reduced.
