The dust collection system comprises of pre-separator and filtration sections. The pre-separation process increases the lifetime of filter bags significantly by collecting the bigger particles and letting only the tiniest particles into the filter bags.
SIGMA reverse flow filter with elliptical ARAMID bags is widely dimensioned for efficient operation complying with the environmental standards. The central computer controls the cleaning of filter bags by automatically opening the lateral gates in pre-determined time intervals.
The recovered dust is collected at the hopper below and a central screw conveyor extracts the dust to be used as recovered filler. Outer surface of the filter and the collecting hopper are insulated with rock wool for maximum heat efficiency.
