Corundum Planetary Grinding Jar with High Chemical Corrosion Resistance

Corundum Planetary Grinding Jar with High Chemical Corrosion Resistance

Product introduction

Name of corundum, which comes from India, is a mineralogical name with its hardness nest to diamond. Corundum is mainly used for grinding advanced materials. Corundum jar with zirconia balls .is a best matching way for wear-resistance. Though the corundum has a strong hardness, it is also fragile, please prevent falling to the ground and high strength impact behavior when using it. We can customize various types of vacuum jar according to customer’s needs.
