SERVING our Clients FOR more Than 50 YEARS
The Story of GT Zesor AG
1971 - 1985
1971 The K. Gisiger-Technik company was founded in Messen, Switzerland.1974 The first hammer mill for grain was successfully launched on the market.
1978 Further development of the hammer mill into a universal fraction mill for processing wood. Often used as an alternative to knife ring flakers due to the higher economic efficiency and consistency of the end product over the entire operating time.
1985 Development of the first knifeless chipper for the production of fibrous and long wood particles. Thanks to the longer wood particles, you get an ideal input product for the production of particleboard.
1988 - 1998
1988 Development of the double trough glue blender. The fibrous and long particles were unfortunately broken and smoothened in the glue blenders used in that time. Gisiger Technik therefore developed the particle-protecting double trough glue blender to maintain the quality of the particles.
1991 Development of the first chipper for recycled wood which produces cleanable chips and is largely unaffected by fragments like metal, stone etc.
1998 Development of sorting machines for continuous cleaning and sorting of recycled materials e.g. wood that is contaminated with textiles and cannot be processed with normal screens.
2004 - 2022
2004 Due to a restructuring of the management, Gisiger Technik became the present company GT Zesor AG. Until today, the "Gisiger" machines for the energetic processing of wood and other renewable raw and residual materials are further developed and refined.2010 Construction and opening of the new production and assembly site in Grafenried. The expansion of the production area was in response to the increasing demand for the products of GT Zesor AG.
2013 With the redesign of the successful product line of the universal fraction mill, the foundation was set to still be one step ahead of the market requirements.
2022 Handover of the management to the third generation. The story of GT Zesor AG continues. Official announcement.

APPLICATION OF THE PRODUCTS
SUITABLE FOR A VARIETY OF RAW AND RESIDUAL MATERIALS
Our high-quality products are suitable for numerous applications. Thanks to the proven modular system, the products can be used in a highly flexible and profitable manner. The universal usability of our own products allows the processing of a wide range of raw and residual materials.
- Residual wood from forestry and wood processing into boards, moldings, fuel chips and heating pellets
- Packed and waste wood into boards, moldings, heating fuel
- bark and organic waste to peat substitutes and soils for horticultural use
- Wood shavings and wood chips into clay aggregates for increased porosity of building bricks
- Grain to food and animal feed
- Other annual plants to animal feed, board materials, compost, heating fuels
universal fraction mill
Hammer mill - USZ
The universal fraction mill (USZ) has a wide range of applications. Due to the interaction of impact tool, impact plates and separating screens, the wood is chipped parallel to the fibers with a low coefficient of friction. The size of the chips is defined by the screens.
- Suitable for wood digestion wet and dry
- Suitable for very wet wood, up to 150% atro
- Extremely easy to maintain and handle
- Additional equipment such as dosing silo, heavy material separator, magnetic box, base frame, discharge screw etc. available from own production
- Capacity: up to 20 t atro/h
- Powertrain: up to 710 kW
knifeless chipper
SHREDDER - HZ
As a result of the fiber-parallel digestion, fiber chips of a large degree of slenderness are produced. These high-quality fiber chips are excellently suited for further digestion or, depending on the application, can be used directly.
- For the production of extremely long fiber chips
- Significantly lower maintenance costs per ton of processed material compared to knives
- Suitable for the production of particleboard
- Capacity: up to 50 t/h
- Powertrain: up to 1000 kW
Double trough Glue Blender
Blender- M
For gluing medium layer chips for construction board all the way to fine chips for the top layer of particle board. Equal and chip-protecting distribution of the glue on the chips. Optimal re-mixing of the chip mass so that a homogeneous and constant chip mixture can be delivered.
- Minimum glue consumption
- Wide range of adjustment possibilities
- High availability with minimum required cleaning and maintenance downtime.
- Capacity: up to 50 t/h
DISC Screen
FOR COARSE AND FINE SORTING
Unaffected by contaminated material. Suitable for recycled wood with metallic impurities.
- Disc screen for rough sorting
- Fine disc screen design for fine sorting
- Unaffected by impure material
- Can be combined with other sorters in one unit
- Working width: up to 2200 mm
- Capacity: up to 50 t/h
Roller Screen
ROLLer AND MICRO ROLLer ScreenS
The roller screen for fine sorting for different particle sizes and especially for separating fine material containing sand.
- Replaceble Rollers
- Hardened roller surface
- Adjustable roller gap
- Combination with other sorters in one unit possible
- Working width: up to 2200mm
- Capacity: up to 50 t/h
METAL SEPARATOR
Magnet Box - MAG
For the extraction of unwanted ferromagnetic impurities in the manufacturing process. For improved protection of the machine.- Tailor-made equipment in combination with the universal fraction mill (USZ)
-
Proven design
- Width: up to 2200 mm
Gravity Separator
PNEUMATIC Gravity SEPARATOR - PSA
For the extraction of heavy particles in the manufacturing process. For improved protection of the machine. The difference in density of the materials separates unwanted particles from the good material.
- Reliable at different levels of humidity
- Suitable for a wide range of applications with different throughput rates
- Proven design
- Width: up to 2200 mm
DOSING AND DISTRIBUTION EQUIPMENT
CAN BE COMBINED WITH STORAGE CONTAINER FOR UNVIVERSAL fraction mill (USZ)
