US $200-$400 / Cubic Meter
Lessing rings also are one sort of Random Packaging, fabricated from ceramic, that was manufactured by raschig ring.
Lessing ring you find (size ranges from 80-200mm) is usually be utilized as supporting medium on at the bottom end of the packed column.
They are highly dense and superb acid and heat resistive while comparing to rest Random Packaging.

Alkali and Acid resistive.
Substantial flux.
Pressure drop is low.
Mass transfer rate is efficient.
Compressive resistance.
You can use them in drying columns of metallurgy, chemical, environmental and gas protection zone..
We widely use them as supportive material in lower portion of tower.
You can purchase these packaging as per various methods such as
Big bags on wooden bunk, plastic woven bags, carton
Packed towers utilize as a media for chemical exchanging and they are the foremost simple devices utilized in the industry for chemical contact improvement.
Within the column it's necessary to keep up a good mass transfer, thus it's vital that packing is chosen which can support an oversized expanse for mass transfer.
The Normal Price is $200.00 to $400.00 per m3
In a common distillation tower, you can use lessing rings as a supportive medium for optimizing surface area over that reactants will move and react whereas minimizing the entanglement of the establishment.
