Log diameter first, then cutting length

Log diameter is the number that eliminates most of the range immediately. The BBS350 mills logs to 360 mm diameter, the BBS550SMART and BBS550SMART-G to 550 mm, the BBS810SMART and BBS810SMART-G to 810 mm, and the BBS920PRO and BBS920PRO-G to 920 mm. Cutting length is the second filter and is set by the track: 2.1 m in basic form on the MOBAS2, 2.4 m as standard on the BBS350 with 1.5 m track sections, 3.2 m on the BBS550SMART and BBS810SMART, and 5.2 m as standard on the BBS920PRO. A mill that fits the diameter but not the length will not saw the logs in your yard.

Electric or petrol is a site decision, not a machine decision

The BBS pairs exist so the same capacity can be bought either way. Where 400 V three-phase already reaches the sawing bay, the electric versions remove fuel, exhaust and engine servicing: 5500 W on the BBS550SMART, 7500 W S1 on the BBS810SMART, 11000 W S1 on the BBS920PRO. Where there is no supply at all – a forest landing, a new site, a mobile operation – the petrol versions carry their own power: an 8200 W Loncin G390F on the BBS550SMART-G, a 9000 W Loncin G420F on the BBS810SMART-G, and a 16800 W RATO R740D on the BBS920PRO-G. The petrol 550 and 810 mills also run their bands at 1200 m/min against 1080 m/min.

The two exceptions: BBS350 and MOBAS2

The BBS350 is the only mill here offered on 230 V single-phase, as BBS350_230V alongside BBS350_400V, with a 2200 W motor pulling a 2750 x 19 x 0.9 mm band at 840 m/min. That makes the BBS350 the entry point for a workshop with no three-phase supply. The MOBAS2 goes further and has no engine or motor of its own at all: the operator’s chainsaw bolts on with the supplied M8 adapter and becomes the power head, on a 58 kg frame giving 2.1 m of cut in basic form.

Space, handling and sawdust

A sawmill needs length rather than area, plus room to roll logs on and to stack boards off. The BBS920PRO alone occupies 6450 x 2360 x 2210 mm, and every mill needs clear working space along both sides of the track. Ground must be firm and level along the whole track length or cuts will not stay parallel. Sawdust is produced in volume rather than as fine airborne dust, so the requirement is a place to collect and clear it and, on petrol machines, open-air running for exhaust – not the ducted extraction an indoor bandsaw needs.

Blades, guides and running cost

Bands are the consumable that decides how a sawmill performs, and each machine takes its own length: 2750 x 19 x 0.9 mm on the BBS350, 3658 x 32 x 1.1 mm on the BBS550SMART, 4015 x 34 x 1.1 mm on the BBS810SMART. Buy bands in multiples so a dull band is swapped rather than pushed. Coolant or lubricant for the band is part of daily running; the BBS920PRO-G carries a coolant tank of roughly 2 l.

What the quotation depends on

The quoted figure for a log band sawmill is driven by capacity and configuration: log diameter class, how many track sections are supplied and therefore what cutting length you get, electric or petrol drive, powered height adjustment and head feed as fitted to the BBS920PRO and BBS920PRO-G, the starting band package, plus delivery to your site in Georgia, assembly and commissioning. Say what diameter and length of log you actually cut when requesting the quotation.
