FIELD: coal industry; municipal services; other industries; methods and devices for production of the grained solid fuel. ^ SUBSTANCE: the invention is pertaining to the process of production of the grained composite fuel, which is intended for usage in the communal heating supply systems or in the household purposes. The method of production of the grained solid fuel with the help of the installation includes grinding of the coal fines, introduction in the composition of the fuel of the ground vegetable additive (for example, the sawdust or the beet press), their joint grinding in the rotary roller mill, sending of the part of the produced mixture in the volume near to 1/3 to mixing with the binder and formation of the seed grains in the turbo-blade mixer. Further route the received mass of seed grains and the remaining part of the mixture in the volume near 2/3 from the mixer for granulation into the plate granulator. The binding is also routed in the granulator to form the seed grains. The produced granules of the spherical shape in the narrow range of the dimensions within 15-30 mm are dried and cooled in the sectional dryer and packed by means of the weighing-and-filling machine into the tare having the form of the cardboard boxes of the different dimensions intended for usage in the capacity of artificial fuel wood. The technical result of the invention consists in the reduced power input for the production process, simplification of the production process, improvement of ecology, the increased efficiency of production of the final product. ^ EFFECT: the invention ensures the reduced power input for the production process, simplification of the production process, improvement of ecology, the increased efficiency of production of the final product. ^ 5 cl, 1 tbl, 1 dwg, 8 ex |
