Introduction
12inch,15inch,17inch,20inch,23inch single or double chamber filter box can be offered or customized according to requirements.filter box lining is made of high refractoriness precast material,in normally used service life can be 12 months.it features Thermal shock resistance,non stick aluminium,corrosion resistance,non carbonation.
Insulation of filtration system adopts high strength Low thermal conductivity qualified insulation board and nano board.
Filtration system cover is made from light castable and with electronic heating part.
Heating time:room temperature – 700℃≤4 hours,600-850℃≤2.5hours, heat preservation while casting pause.
Electric motor is powered by three-phase 380VAC.50Hz, the control power is single-phase 220VAC.50Hz, and the power of a single device is 45KW.it has anti-interference.
Lifiting system: electric cylinder lift and manually rotate opening system.
Filtration system shell: steel plate of 10mm thickness.
