Pellets - Import export

The mechanical counterflow cooler for pellet is designed to cool hot pellets by means of a counter-flow stream of cool air which enters the cooler chamber from the bottom through the inlet at the bottom of the device and leaves it through the outlet located at the top of the cooler. An corresponding layer of material is maintained in the cooling chamber which is fed through an inlet sluice located in the upper part of the cooling chamber. When the maximum filling level in the cooler is reached, the sensor activates the discharge grate, which cyclically discharges the cooled product into the discharge hopper until the rated minimum level is reached. The minimum and maximum fill levels in the cooler chamber is regulated by manually adjusting the position of the fill sensors. In the lower part of the cooler, there is a discharge mechanism which ensures even removal of material from the cooler chamber.

Preparation system for granulation (PSfG) is our proprietary solution whose task is to stabilise and maintain the moisture content of the material fed to the granulation section at a level of ± 0.5% and to dose an appropriate amount of binder (e.g. corn meal), which significantly impacts on improving the physical and chemical properties of the final product. Stable moisture content and the addition of the proper amount of binder have a key impact on obtaining and maintaining high quality parameters of the pellets produced, such as: calorific value, hardness, strength, amount of ash after burning and dust content in the pellets. Proper moistening and maintaining the humidity of the sawdust at the required level greatly facilitates the compacting and binding of the material particles into granules, and thus enables to achieve a uniformly high quality of granules.

The new generation of German Graf Equipment GmbH Gorilla pellet mills is especially designed for applications with very hard pelleting conditions in terms of raw material quality in limited working space and while keeping all production norms. The production of wood pellets is one of these applications. In fact, Gorilla is the first pellet mill designed for the biomass industry, including wood biomass, with direct drive system, without gearbox or V-belts. The new pellet mill performs a high efficiency thanks to its powerful torque motor, saving around 20% of energy, compared with the conventional drive systems. An unquestionable advantage of all Gorilla pellet mill is their modular design and a large die speed range (from 4 to 8 m/s) without loss of torque, which allows to meet even the highest technological standards of pellet production. Gorilla pellet mills assure superior finished pellet quality with a high PDI (Pellet Durability Index).

We design, manufacture, build, train and service The pellet production lines designed and installed by our company offer capacities ranging from 2 t/h to 20 t/h. The capacity achieved naturally depends on the number and power of the machines and equipment comprising the production line. Pellet production lines – the offer: •design (technical conceptual design, formal arrangements, technical documentation, manuals, cost calculation), •supply (machines, devices, measuring and control apparatus, control cabinets, and all installation materials), •installation (machines, devices, control cabinets, measurement, control and feed wiring, post-installation testing, acceptance measurements), •software (controllers, operator panels, visualisation and control systems), •commissioning (machines, devices, control cabinets, control and power installations), •training process operators, programmers and IT technicians and technical human resources, •service within the warranty period and beyon

Screw conveyorsare used for transporting sawdust, wood chips, pellets and other bulk materials. Conveyor housing is made of structural steel with Magnelis® coating. Wormwheel is made of thick-walled steel pipe with 10 mm thick spiral welded to the pipe. End necks welded on both ends of the wormwheel are designed to be mounted in high-quality self-aligning ball bearings (SKF or INA/FAG) with UCF housing. Additionally, our screw conveyors are equipped with rotation monitoring sensors and inspection hatches with overflow sensors.Depending on the requirements and purpose belt conveyors could work with capacities from 15 m3/h to 100 m3/h. Screw conveyors (also known as auger feeders) are used in various industries, and their design can be adapted to the specifics of each industry, if necessary. The screw feeders we manufacture are part of the pellet production lineswe design and build, and ensure stable, even feeding of the raw material to the next production stage.
