92% Alumina Grinding Cylinder 32x32mm
Product Overview
What Is High Alumina Grinding Column
Alumina grinding column refers to the high-temperature calcined Alpha alumina powder as raw material, through batching, grinding, powder making, molding, drying, firing, and other processes
Alumina ceramic grinding columns make great ceramics, glasses, and enamels in chemical factories and other industries with ball mills, can-type mills, and vibration mills as their main machinery. Al2O3 Alumina grinding cylinder can also be used in these industries: metallic minerals, non-metallic minerals , silicon carbide, talcum, white pigments, cosmetics, cement, building materials.
High Alumina Ceramic Grinding Column applications
Apart from grinding usages, you can form rubber-backed ceramic wear liners with our alumina grinding cylinders. The main application for Alumina Ceramic Column is within the mining industry.
We suggest Al2O3 alumina grinding cylinders for stirred mills and ball mills preferably. Alumina grinding columns are widely used in different types of ceramics, enamels, glass, chemicals, etc. due to their excellent characteristics such as high strength, high hardness, high wear resistance, large specific volume, small volume, high-temperature resistance, and corrosion resistance.
high Alumina Grinding Column advantage
The alumina grinding column has a grinding efficiency and abrasion resistance far exceeding ordinary ball stone and natural pebbles. It is an excellent grinding medium for fine grinding equipment such as ball mills, pot mills, and vibration mills.
No abrasion, no corrosion, and no erosion. Alumina ceramic grinding columns resist almost everything. Acid, alkali, chips, extreme heat, and abrupt temperature changes, etc. Al2O3 Alumina grinding cylinder are also pollution-free, easy to clean, and 3-5 more durable than natural stone liners, and 23 times more durable than rubber liners. Installation and milling time are reduced at a minimum, while efficiency is augmented at a maximum.
• Wear-resistant low loss
• high-temperature resistance
• corrosion resistance
• High Mechanical Strength
