5 FAQs of 75% Alumina Ceramic Grinding Balls

What are 75% alumina ceramic grinding balls made from?
They are made mostly from alumina. Alumina makes up 75% of the material. The rest includes other ceramics and binders. This mix gives them good strength.

Why are these balls so dense?
The high alumina content makes them dense. Density makes them heavy for their size. Heavy balls hit harder during grinding. Harder hits break down materials faster.

Do they wear out slower than steel balls?
Yes, they wear much slower. Alumina ceramic is very hard. Hardness resists wear. They last much longer than steel balls in many grinding jobs. This cuts down replacement costs.

Can they handle chemicals?
They handle many chemicals well. Acids and alkalis usually don’t harm them. This makes them good for chemical processing. They won’t rust like steel balls either.

Are they cost-effective?
They cost more upfront than steel balls. But they last much longer. Their long life means less downtime for changes. Less downtime saves money over time. Lower wear also means less contamination in your product.
