More info

Mixed alumina is a secondary product that is produced from ceramic grounding wheels and reclaimed alumina dust from the blasting and grinding industry. An inexpensive, iron-free product is produced after extensive processing at our recycling plant in Ballenstedt. Our customers like to use mixed alumina to give glass a satin finish or to process fine castings. We will be happy to help you.
