Start-up of PM 1 from Bukovec, New SPL (120 tpd), New Pulp Processing Line (40 tpd)

The following items were supplied for the machine delivered two years ago: a new complete stock preparation line, capacity 120 tpd; a new pulp processing line, capacity 40 tpd; and a new water treatment plant with flotation equipment Sonoflot FH-150. The machine produces fluting and liner with a substance of 120 to 175 g/m² from 100 % brown waste paper. It is reconstructed for the capacity of 3.500 kg/h, which represents an approx. 30 % capacity increase compared with the original capacity.
