METHOD OF PRODUCING OF BRIQUETTES AND INSTALLATION FOR BRIQUETTES' MANUFACTURING Russian patent published in 2009 - IPC C10L5/00 B30B9/12 B30B11/24 B27N3/28 

FIELD: packaging industry.

SUBSTANCE: invention relates to installation and method of producing of briquettes from wastes of vegetable raw materials in the form of sawdusts of husks, peels etc. used in the capacity of secondary raw materials or for burning in domestic and industrial fire chambers. Installation for manufacturing of combustive briquettes, contains case with loading tray, outfitted by agitator, taper chamber, located by converge end to exhaust port, drive compressing arrangement in the form of fixed lengthwise taper chamber of screw with decreased to the side of exhaust port diametre and discharging into exhaust port, outfitted by changeable moulding bush and thermal processing chamber, herewith it additionally contains division mechanism on measured section, installed at withdrawal from exhaust port, implemented in the form of limiter installed with ability of movement and position fixation on guide, fixed on outlet of exhaust port, thermal processing chamber is installed co-axial to exhaust port and taper chamber up to its middle part, herewith screw is implemented at a constant pitch and with changeable end, and agitator is implemented in the form of two specular located driving screws, fixed on walls of loading hopper with ability of blade rotation towards to each other and in the direction, perpendicular to axis of compressing device-screw. Also it is described method of producing of combustive briquettes with usage of this installation. Method includes feeding of vegetable raw materials with humidity 4-12% and breakup 2-10 mm, its compressing, following forming and division, herewith briquettes are additionally thermally treated, herewith formation is implemented continuously and simultaneously with thermal processing, implemented at 150-250°C, depending on type of raw materials, forming briquette of required section, achieved by changeable end of screw and changeable mould bush of exhaust port, after what it is implemented division for measuring sections.

EFFECT: proposed installation and method provides receiving of full-strength briquettes of length of cut of the required section and dimension.
