The consumable price of mining enterprises accounts is the largest proportion of the total cost of mines, learn how to reduce the cost of mine consumption has always been a problem in the entire mine field. Ceramic balls have been used as grinding media in fine grinding for a lot of years. They are mainly utilized in high-speed rotary fine grinding equipment, reminiscent of ISA grinding, Smith VXP grinding, Metso SMD grinding, etc. These devices are characterised by high pace between media. The velocity distinction fashioned by the motion produces a grinding motion to grind the material. The vertical spiral agitating mill primarily relies on the low-speed rotation of the spiral agitator to drive the pressing power and shearing force generated by the grinding media to grind the material. The density of the media is among the most important factors affecting the grinding effect.
High-chromium steel ball is a traditional grinding medium for vertical mixing grinding in mining business, it has high hardness and good wear resistance. Strange ceramic balls are lighter in density and have a decrease 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 recent years.
Accumulate below advantage of ceramic grinding media to your reference:
1. Energy saving
Under the identical grinding process conditions, the quantity of ceramic grinding media is large, but the total mass is small, and the energy saving impact could be very obvious.
2. Reduce the consumption of produced media
By way of calculation, the yield of medium-produced medium metal ball is 0.sixty eight~0.eleven kg/t, while the consumption of ceramic grinding media is 0.052～0.063 kg/t, which is calculated by the worth 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 may be reduced by about sixty five%.
3. Prolengthy the service life of spiral liner
After changing 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 steel ball has irregular polygonal bodies after wear, which determines that the ceramic ball is more simply discharged from the volleyball, which can effectively 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 bottom is lower than that of the metal ball.
5. Reduce iron impurity air pollution
For most non-metallic minerals, the impurity content material, especially iron, determines the quality grade of the product. Many non-metal grinding processes are used to reduce iron impurities, and iron removal is normally carried out during processing. If ceramic grinding media is used within the fine grinding stage, the iron impurity contamination can be successfully reduced.
