A grade Corundum planetary Mill Jar

Product Introduction

The special-grade corundum planetary ball mill tank is made of high-quality and high-purity corundum material and has been fully upgraded on the basis of ordinary corundum ball mill tank. Corundum, whose name originates from India, is a mineralogy name. Its hardness is second only to diamond. It is currently one of the most ideal high-performance grinding media containers.

Compared with ordinary corundum jars, special-grade corundum jars have significantly improved raw material purity, sintering process and structural density, and have higher mechanical strength, better wear resistance and longer service life. Special-grade corundum jars and zirconia balls are a classic high-end wear-resistant combination that can meet more stringent grinding process requirements.

Performance comparison with ordinary corundum jars

Precautions for use

1. Loading requirements

   • It is recommended that the filling amount should not exceed 2/3 of the tank volume.

   • When dry grinding, the total volume of materials and grinding balls should be 1/3-1/2 of the tank volume.

   • When wet grinding, the material should be completely immersed in the liquid

2. operating instructions

   • Avoid idling operation and ensure there is enough grinding media in the tank

   • Check the tank regularly for cracks or wear

   • Use appropriate protective equipment for operation

3. Cleaning and maintenance

   • Clean in time after use to avoid material residues

   • It is recommended to use soft cleaning tools to avoid scratching the inner wall

   • Keep dry and avoid humid conditions when storing

4. Safety warning

   • It is strictly prohibited to use it beyond specifications (such as over-temperature, over-pressure, etc.)

   • Handle it with care when moving and installing to avoid collisions

   • If cracks or damage are found, stop using it immediately

Product Features

Excellent high temperature resistance

Special-grade corundum tanks can withstand working temperatures up to 1600°C, far exceeding the 1400°C limit of ordinary corundum tanks, and are suitable for long-term grinding operations in high-temperature environments.

Enhanced mechanical strength

Through optimized raw material ratio and advanced sintering process, the impact resistance and bending strength of the special grade corundum jars are about 30% higher than that of ordinary products, and the service life is significantly extended.

Excellent corrosion resistance

It has excellent resistance to chemical reagents such as acids and alkalis, and can handle various corrosive materials without affecting product purity.

Higher material purity

Special-grade corundum jars use higher-purity raw materials to ensure that no impurities are introduced during the grinding process, and are especially suitable for applications with extremely high purity requirements.

fine microstructure

Special-grade corundum material has a denser and more uniform microstructure, which effectively prevents material penetration and adhesion and facilitates cleaning and maintenance.
