70% ZTA320 Alumina Ceramic Balls
Introduction
Mainly used in calcium carbonate, kaolin, zircon sand, pigment, dyes, graphite, coatings, metal mining industries used as grinding and dispersion media. The beads can also be used for shot peening for shot peening polishing and other metal surface treatment. According to the customer’s different grinding equipment, we can match different density grinding beads.
Advantages
Good roundess, high sphericity, the surface has excellent gloss. The product is compact in sintering and has no defects such as porosity and so on.
Excellent toughness, higher crushing strength than ordinary alumina beads non-fragmentation in long-term high-speed operation.
Good stability, acid and alkali resistance.
Low equipment attrition.

Company Info.
Zibo Huao New Materials Co.,Ltd is located in Shandong Zibo, it is
a professional company for R&D Design, manufacture and sale
Alumina Particular kind of Ceramic Products. There are two kilns
which can manufacture alumina grinding media including ceramic
balls, linings, cylinders, high pure inert balls(92%,95% and
99%),wear-resistance bricks and tubes. There are 16 sets big ball
mills, 20 sets is opressing machines and advanced lab, in lab there
are full set of highend experiment instrument and testing
equipment, professional R&D team. Huao can supply very good
quality products and excellent after-sales service to the users of
China and abroad, because it has the advanced production
technology, perfect quality control testing system, the modern
enterprise management mode. Huao cement dry grinding media have
different type, there are balls and cylinders,comparing with steel
grinding media, it is more high temperature resistance, more high
hardness, more high strength,lower wear loss, corrossion
resistance,lower expansion coefficient and more light weight, these
performances solved the problem and defect of low capacity, big
wear loss and easy to crush for using the nonmetal grinding media,
so the users achieve the purpose of saving power, lengthen maintain
period of equipment, reducing the repair cost and more environment,
thus to get more profit and have good competitiveness. Huao always
adhere to the principle of quality first, customers first and
reputation first, their products are widely used in ceramic,
mining,petroleum, chemical industry, electric power, papermaking,
cement,aerospace, military industry and other fields. The markets
covered Europe and the United States, the Middle East, Sountheast
Aisa,Japan, South Korea and other regions and countries. Warmly
welcome friends from all over the world to join hands with Huao and
thank you for your support!
