SPECIAL ROLLER KILNS

AIR(GAS) TIGHT HEART ROLLER KILNS for SINTERING Soft Ferrites Mn-Zn

The technology for firing soft ferrite Mn-Zn more diffused is the use pusher kiln completely electric.
The technology proposed by TECHNOKILNS is an air tight heart roller kiln,
where the firing is partly by gas and partly electric,with the following advantages :

• The roller kiln doesn't need a external after-burner the kiln himself in pre-heating zone(BBO), it works like after-burner to high turbulence With complete combustion of the substance organic without break-up of the pieces of greater dimensions.
• The heating from room temperature up to the maximum temperatura(1350°C) is gotten with burners, non with electric resistances, this it behaves a greater thermal exchange with consequent high speed reaction and completion of the chemical reaction of Mn, Zn, Fe, in smaller times and therefore a high final density of the magnet with consequent improvement of the magnetic ownerships.
• According point 2, cycles of cooking very more breves : with heart rollers kiln the cycle is from 8-12 hours against the 24 hours of the pusher kiln nhen with kilns of peer length and width the roller kiln to has a superior productive ability. The roller kiln like pusher kiln, can be load two layers.
• Consumptions of Nitrogen,Kw, more lower part.
• In the roller kiln the cooling area is made by air heat changer unlike the pusher kiln where the cooling is gotten with Water.
• The roller kiln can reach up to 50 ppms of Oxygen
• Possibilities to automatize load and unloading of the kiln.
• In case of accidents during the march the time of stop is least. In case of accidents in the pusher kiln, the kiln must be swich off and it needs to attend the suit cooling.
