NOVELTY - Producing slurry comprises: putting garbage and biomass installed on a garbage unloading table (1) into a garbage classifying pond (2), puncturing, tearing the bag garbage and other concentrated garbage balls, separating the garbage, stirring the filled substance in the pond and precipitating the garbage with steel, sand and stone and glass; taking out the bottle garbage and floating garbage; filtering the floating garbage and inversing the filtered garbage on a loading table (4); and introducing the mixture in the pond into a slurry mixing pond (3) and then adding coal powder.    USE - The process is useful for preparing slurry and solid fuel.    ADVANTAGE - The process has high garbage processing degree and garbage use ratio and can completely process garbage.    DETAILED DESCRIPTION - Producing slurry and solid fuel by using garbage and biomass comprises: (a) putting the garbage and biomass installed on a garbage unloading table (1) into a garbage classifying pond (2) filled with water, puncturing, tearing the bag garbage and other concentrated garbage balls, separating the collected garbage, stirring the filled substance in the garbage classifying pond and precipitating the garbage with large density of steel, sand and stone and glass; (b) taking out the bottle garbage and floating garbage which is longer than 100 mm or has diameter of larger than 10 mm by a refloating device; (c) filtering the floating garbage which is shorter than 100 mm or has diameter smaller than 10 mm through a screen with diameter of 50 mu m and inversing the filtered garbage on a loading table (4); (d) introducing the mixture in the garbage classifying pond into a slurry mixing pond (3) by a screen with diameter of 50 mu m, after completely flowing the mixture in the garbage classifying pond into the slurry mixing pond, adding coal powder with granularity of smaller than 50 mu m into the slurry mixing pond, obtaining coal water slurry after uniformly stirring the mixture added with coal powder and pouring the garbage inversed on the loading table into the material delivering device by the loading table; (e) delivering the garbage into a high concentration stuff grinder (51) by a material delivering device, grinding the garbage by the high concentration stuff grinder and entering the garbage grain and slurry mixture crushed by the high concentration stuff grinder into the material delivering device by the material outlet of the high concentration stuff grinder; (f) delivering the garbage grain and slurry mixture into a solid-liquid separator by the material delivering device and delivering the garbage grain into a solid forming machine by the solid material outlet of the solid liquid separator; and (g) preparing the garbage grain into solid fuel by the forming mold of the solid forming machine and finishing the preparation of the solid fuel. An INDEPENDENT CLAIM is included for a production device for producing slurry and solid fuel by garbage and biomass, comprising an unloading table, a garbage classifying pond for separating the garbage, where the garbage unloading table is connected with the garbage classifying pond, a slurry mixing pond which is installed on the side of the garbage classifying pond, a passage which is installed between the slurry mixing pond and the garbage classifying pond, where the side of the garbage classifying pond is further arranged with a loading table matched with a forming device for forming the solid fuel.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a process for producing slurry and solid fuel using device.    Garbage unloading table (1)    Garbage classifying pond (2)    Slurry mixing pond (3)    Loading table (4)    High concentration stuff grinder. (51)
