DRY SAND AND STONE SEPARATION AT RECEIVING DECK


ANDRITZ Solution

• Dry debris separation • Biomass recovery

Benefit

• Less sand in biomass for boiler

• Bark (loose) and debris separation provides better chip and pulp quality and reduces wear of chipper knives • Shaking rollers • Dry separation rollers • High pressure log wash

• Stone separation protects the chipper knives against wear and

damage • Water stone trap • Acoustic stone detection

• Metal detection before the chipper protects the chipper against

damage

• Highest and most uniform chip quality at the market • Produces with 33 degree feed angle thinner chips than any

other brand at the market; results typically 1,5% -unit yield improvement

• Max. Capacity is > 500 m3/h; • Disc diameter 3,87 m with 18 knives • Max. Dia wood is 900 mm • Volume of surge bin is big enough to balance big logs - 45 m3 • Runnability is appreciated – operators love it! - much less

blockages in infeed than with drop feed chipper • Special 4-motor drive saves in running and electrification costs

• 127 pcs sold since 2001; 23 pcs of EXL since 2009

High capacity without compromises in chip quality

HHQ-CHIPPER - THE UNIQUE HORIZONTALLY FED CHIPPER

• Chipper cut the logs into chips of suitable size for pulping process. • Maximizing amount of quality chips from varying wood supply at high capacity • Effective utilization of wood raw material due to minimum production of fines (lost fibers) • HQ-chipping geometry leading to uniform chip size distribution results

CHIPPING — OPERATING PRINCIPLE


Benefits summary • Improved operator safety due to low weight, easy to handle knives. • Only one operator needed for knife change. • Exact hardening and cutting edge for ~2.5x longer knife life and higher

uptime and production potential. • Integrated counter knife – optimum performance for high chip quality. • No knife grinding – always sharp knifes for best chip quality • Full service contracts available

• Particles, which among the chips are not suitable or preferred for pulping process, are separated in chip screening.

• Oversized are separated, resized and returned to accepts • Fines are separated and sent to bio fuel • Over thick can be separated, resized and returned to accepts

• Fines screening of ANDRITZ HQ-chips is not necessary. • Fines screening creates a fiber loss. • Fines screening is necessary in case of purchased chips.
