Case study
WOOD PRODUCTION FOR LARGE-SCALE DISTRIBUTION IN THE US
Input: logs of various diameters from 10 cm to 70 cm, log lengths up to 20 metres
Output: dried firewood from 40 cm in length bagged and destined for large-scale distribution
Customer requirement: to produce firewood on a large-scale and semi-automatically from hardwood logs with diameters from 10 to 70 cm and lengths up to 21 m.
Solution by Pezzolato:
- log loading system and sectioning into a size suitable for the cutting unit;
- disc splitting unit TLA 18 (disc size 1800 mm for logs up to 710 mm in diameter and length up to 6.8 metres)
- automatic vertical splitting station TB 900 (for larger logs);
- manually loaded horizontal splitting stations;
- rotating screener, with noise reduction system, for cleaning the processed logs and separating flakes, bark and sawdust;
- hydraulically pivoting outfeed conveyor belt for stacking firewood up to a height of 5.50 m for an operational reach of 110°.
The productivity of this equipment is more than 200 cubic metres per shift with only three operators.

WOOD PRODUCTION FOR LARGE-SCALE DISTRIBUTION IN SWITZERLAND
Input: beech logs 18 cm to 70 cm in diameter and 6 m long
Output: dried firewood in bulk, packed in pallets and packed in cardboard boxes and production of firelighters
Customer requirement: to produce firewood on a large-scale and automatically from hardwood logs with diameters which can vary from 30 to 70 cm and lengths up to 6 m.
Solution by Pezzolato:
- log loading system and transfer towards the cutting unit;
- cutting unit TL 1800 (disc size 1800 mm for logs up to 710 mm in diameter);
- cut log translation unit
- automatic vertical splitting station TB 900;
- cleaning system of the processed logs with a star screener located at the exit of the splitting station, in order to separate flakes, sawdust and bark from the processed logs, which are unloaded into the drying container by means of a hydraulically pivoted conveyor belt;
- dried log cleaning station with a rotating screener, equipped with a noise reduction system, to clean the dried logs by separating them from flakes and bark.
The average productivity of this equipment is 20 cubic metres per working hour with a single operator.
Case study
SPECIAL EQUIPMENT FOR PRODUCING CHARCOAL IN EASTERN EUROPE
Input: logs of various diameters from 5 cm to 50 cm and lengths up to 5 m
Output: cut and split logs intended for coal production
Customer requirement: to produce firewood on a large-scale and semi-automatically from hardwood logs with diameters which can vary from 5 to 60 cm and lengths up to 6 m.
Solution by Pezzolato:
- No. 3 log loaders equipped with a log separator, in order to feed the cutting unit with logs up to 6 m long;
- No. 3 automatic splitting units TLA 15, equipped with a 1500 mm diameter splitting disc, feeding conveyor 80 cm wide and 6.8 m long, designed to process logs up to 600 mm in diameter and large bundles of mixed timber;
- No. 1 automatic vertical splitting station TB 900 (for larger logs);
- No. 4 horizontal splitting stations, manually loaded, with a 20 ton thrust force; grid with an automatic centering system, equipped with a 2/4/6-way mobile splitting wedge;
- No. 3 horizontal splitting stations, with a 32 ton thrust force, grids with an automatic centering system, equipped with a fixed 2/4/6-way sector and a removable/interchangeable 16-way sector;
- A series of conveyors to collect the cut and split material exiting the splitting stations and move it to the feeding system for coal production.
The minimum guaranteed productivity for this equipment is 570 cubic metres per day with 10 operators (3 of which operating on the TLA 15 cutting units) in order to keep the coal production at full capacity.
Case study
AUTOMATIC EQUIPMENT FOR LARGE SCALE DISTRIBUTION IN GERMANY
Input: logs ranging from 30 to 85 cm in diameter and up to 6 m long
Output: high-quality firewood
Customer requirement: to produce firewood on a large-scale and semi- automatically by a single operator, from bundles of hardwood logs or single hardwood logs with diameters up to 85. Automated storage of the logs produced inside special containers for the drying phase. At a later stage, the customer requested the installation of two additional manual splitting stations, in order to better utilise the potential of the splitting unit.
Solution by Pezzolato:
- Log loader with separator in order to feed the cutting unit;
- Automatic cutting station TLA 22, equipped with a 2200 mm diameter splitting disc, feeding conveyor 100 cm wide and 6.8 m long, designed to process logs up to 820 mm in diameter and large bundles of mixed timber;
- Automatic vertical splitting station TB 1200 to process logs of any type with a diameter from 300 to 850 mm, feeding conveyor 1200 mm large;
- “S”-shaped collecting belt, installed at a later date, to serve the manual horizontal splitting stations;
- No. 2 horizontal splitting stations, installed at a later date, equipped with a grid with automatic centering in order to split and refine the logs cut by the operator;
- Cleaning system for the processed logs in order to separate flakes and bark from the processed logs, which are discharged into the drying container by means of a series of hydraulically adjustable and extendable conveyor belts.
