20 years producing experience of alumina ball, 20 days delivery time, reply within 12 hours, ISO9001, SGS - details see: https://www.machineto.com/pure-alumina-ball-10283057

Ceramic Alumina Ball is broadly utilized as thecovering or supportingmaterialsof the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc.

There are lots ofmeritsfor it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.

Notice to ordering goods:
a) When ordering goods, customers should introduce the radical situations of the equipment,
including the sizes of reactors, and the operational temperature etc.
b) Customers should provide the specification, types, and the total content of Si, Al related to the required product.
c) As the inert ceramic ball belongs to the natural tight stacking in the reactors, customers should consult with our technological staff to determine the amounts according to the practical loading volume, and remain 15-20% margins
