Does the Color of a Grinding Wheel Affect Its Performance?
“Judging a wheel solely by color is a simple but unreliable method.
This is because a grinding wheel’s color may come not only from abrasive grains, but also from the binder, added dyes, or even the porosity of the wheel, all of which can affect its appearance.”

Guinea Repossess 51 Mining Licenses! Aluminum Prices Hit Limit Up!

"The recent mining license revocations in Guinea have become a key factor influencing market trends. On May 20, Guinea’s transitional authorities designated several mining rights—including bauxite licenses, industrial and semi-industrial mining permits, and exploration licenses—as strategic reserve areas, further driving up alumina prices. "

The Impact of Sodium Oxide on White Fused Alumina
"Na₂O, as a major impurity in WFA, has a significant impact on its properties. Na₂O mainly forms β-Al₂O₃ with Al₂O₃, reducing the hardness, density, strength, and thermal stability of WFA.

This report provides an in-depth analysis of the mechanisms by which Na₂O influences various aspects of WFA performance, as well as industrial strategies for controlling Na₂O content to enhance WFA quality."

Silane Coated White Fused Alumina For Laminate Flooring

JCT Abrasives supply silane coated white fused alumina with characteristics :
1. High hardness, compact particles, and excellent single-particle roundness.
2. Pure white color, free of impurities, and high cleanliness, ensuring the color and transparency of the coating.
3. Uniform and concentrated particle size distribution, consistent particle shape, achieving maximum wear resistance with minimal dosage.
4. Chemically stable, does not react with acids or bases, exhibits minimal thermal shrinkage, and has excellent flame retardancy.
5. The particle surface undergoes surface modification treatment, enhancing wettability and pe*******on, and improving particle dispersion.

Chinese alumina oxide prices have returned to their pre-increase levels.

The price of alumina rose from around 3,000 to 5,850 over nearly 225 trading days, achieving a price increase of 2,630 yuan. However, it only took 38 trading days for the price to fall from 5,850 back to 3,400, a decrease of over 2,000 yuan. This market trend resembles a roller coaster, soaring to the clouds one moment and plummeting to the valleys the next.

Differences between batch and tilting electric arc furnaces in white fused alumina smelting

Batch (Fixed) furnaces process materials in discrete batches, and it often takes almost 24 hours to smelt one batch. While the tilting furnaces are generally more energy-efficient due to their ability to operate at a constant temperature, and it usually takes 4-7 hours to smelt one batch.

White fused alumina and pink fused alumina from batch (fixed) furnaces have higher toughness and hardness, and better high-temperature resistance and erosion resistance, compared with that smelted in tilting arc furnaces.

JCT ABRASIVES owns 6 batch (fixed) arc furnaces, and the white fused alumina, pink fused alumina and ruby alumina have an excellent toughness.
