What is the alumina content of mid-alumina ceramic balls?
Mid-alumina ceramic balls feature an Al2O3 content of 45% to 50%, with a combined Al2O3 + SiO2 content exceeding 93%, providing an optimal balance of strength and cost efficiency.
What is the maximum operating temperature for these ceramic balls?
The maximum continuous operation temperature for mid-alumina ceramic balls is 1200℃, making them suitable for most thermal and chemical processing environments.
How resistant are mid-alumina ceramic balls to acids and alkalis?
They offer high chemical stability with an acid resistance exceeding 99.6% and an alkali resistance greater than 85%.
What is the crush strength range across different sizes?
Crush strength increases significantly with diameter, ranging from >35 kg/particle (>0.35 KN) for 3mm balls up to >5600 kg/particle (>56 KN) for large 50mm balls.
What are the manufacturing tolerances for different ball dimensions?
Dimensional tolerances depend on size: ±1.0 mm for 3/6/9 mm balls, ±1.5 mm for 9/13 mm, ±2.0 mm for 19/25/38 mm, and ±2.5 mm for 50 mm balls.
