Innovation & Environmental Protection in the Abrasives Industry
Zhengzhou, China (PRWEB) December 24, 2014 -- With the rapid development of the abrasives industry, environmental protection seems more important than ever. iAbrasive offers some suggestions on environmental protection and technological innovation.
Focus on Improving Technological Content in Abrasives Production
1. Adjust Manufacture Techniques to Improve Added Value
Stricter control over the smelting of conventional abrasives, such as fused alumina and silicon carbide, should be made.
2. Produce According to Demand
Conventional abrasives are used for refractory materials. Theoretically speaking, only when the spherical particles are in a proportion of 6:3:1 (coarse: medium: fine) can the highest bulk density be reached. Currently, Barmac, ball mills, and autogenous tumbling mills are ideal choices.
Abrasives used in coated abrasives products should be sharp. There is usually an upper limit to the abrasives bulk density. There is no strict standard for the particle sizes of F sand designed for resin cutting discs.
3. Improve Abrasive Grains Cleanness
The cleanness of abrasives has an effect on the bonding force of finished products. Experiments prove that abrasive grains with higher cleanness have a higher intensity when made into abrasives products or refractory brick.
4. Develop New Products
The emergence of new abrasives products, such as SG abrasives, polycrystalline abrasives, grouped abrasives, and different shapes of abrasive grains is facilitating the abrasives industry to expand to new technological field and market.
Environmental Protection & Integrated Utilization
In the past decade, most of the abrasives companies invested in environmental protection simply to the national policy. There were little concrete parameters for environmental protection. As a result, abrasives companies suffered huge loss. According to incomplete statistics, 90% of the dust-cleaning apparatuses built in the past decade need a second investment. Therefore, abrasives companies should check concrete parameters, such as filter area, the quality and precision of filter medium, system resistance, operation costs, etc.
Measures have been taken by a great many abrasives companies in terms of integrated utilization, such as recycle of heat in fused alumina smelting and reuse of CO in Sic smelting. After all, the importance and necessity energy saving and environmental protection in the abrasives industry are on the agenda.
Though the development track of the abrasives industry is flux and reflux, the overall tendency is rising. Its significance to the national economy is as plain as daylight. While great efforts still need to be made in technological progress and environment treatment.
