Advantage of Ceramic Grinding Media for Mining Business

The consumable price of mining enterprises accounts is the biggest proportion of the total value of mines, tips on how to reduce the cost of mine consumption has always been a difficulty in your entire mine field. Ceramic balls have been used as grinding media in fine grinding for many years. They’re mainly used in high-pace rotary fine grinding equipment, corresponding to ISA grinding, Smith VXP grinding, Metso SMD grinding, etc. These gadgets are characterised by high velocity between media. The speed difference shaped by the motion produces a grinding action to grind the material. The vertical spiral agitating mill primarily relies on the low-speed rotation of the spiral agitator to drive the urgent pressure and shearing power generated by the grinding media to grind the material. The density of the media is likely one of the principal factors affecting the grinding effect.

High-chromium metal ball is a traditional grinding medium for vertical mixing grinding in mining industry, it has high hardness and good wear resistance. Extraordinary 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.

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 large, however 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.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 changing to ceramic balls, the cost of production per unit of production could be reduced by about sixty five%.

3. Prolengthy the service life of spiral liner

After changing with ceramic ball media, the lifetime 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 our 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, 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 steel ball.

5. Reduce iron impurity 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 throughout processing. If ceramic grinding media is used within the fine grinding stage, the iron impurity contamination may be successfully reduced.
