The Fox briquetting presses are able to manufacture materials like wood shavings, sawdust, wood chips, dust and other residual materials into stable, cylindrical briquettes. Compared to loose material, the initial volume will be reduced by up to 90 %. Residual materials transformed into compact briquettes can be used energetically much more efficiantly and sold profitable. A further advantage based on briquetting is the reduction in the danger of fires and explosions. Because of the fact that briquetts are considered as low-flammable like solid wood there aren't any additional costs for complex fire protection regulations. The material moisture content shouldn't exceed a maximum of 18 % ATRO. Furthermore the granule size has to be smaller then 20 mm.
By changing individual parameters, the briquetting presses can be adapted to customer materials, required throughput performances and individual conditions. It's possible to choose from various cylinder sizes, drive engine variants and silo shapes. The filling of the briquetting press can take place manually or automatically. During the material flow via a screw, a belt conveyor or a suction unit, the machine recognizes the fill level of the silo and is able to start and stopp automatically. There is no operating personnel necessary. The produced briquetts can be transported with a briquette transport pipe to the briquette stock without any further use of energy, just by pressure of the hydraulic.
Shavings are fed in the hopper, where it is dosed and supplied by an integrated agitator into the pre-compression unit. In this unit runs a hydraulic piston, which pre-compresses the material and feeds the main cylinder. The hydraulic piston presses the material into the closed sleeve until the adjusted pressure is reached (which is usually set up to 80 bars). Then the sleeve opens and finally a stabile briquette is produced.
