# The Bell-less Top (BLT)

The Bell-less Top (BLT) system represents a major evolutionary leap from the traditional double-bell mechanism.

The BLT replaces the heavy, wear-prone bells with a system of lock hoppers and a rotating chute.

Its core advantage lies in providing precise, non-contact burden distribution through controlled chute rotation and tilting. This sophisticated control over material placement—coke and [iron ore](https://www.o2oh.com/glossary/iron-ore)—allows operators to finely tune the gas flow distribution within the furnace.

This capability directly translates into improved fuel efficiency, higher productivity, and the ability to operate the [blast furnace](https://www.o2oh.com/glossary/blast-furnace) at higher top pressures, thereby securing greater operational stability and performance.
