The invention relates to a biomass fuel production process and production equipment thereof, in particular to a production process and equipment for producing slurry and solid fuels by garbage and biomasses. The production process for producing slurry and solid fuels by garbage and biomasses comprises the following steps: preparing water-coal-slurry through steps of feeding, piercing and tearing,sorting, filtering, adding coal powder, stirring and the like; and then carrying out steps of crushing, separating and forming and the like to prepare the solid fuels. Meanwhile, the production equipment corresponding to the production process for producing slurry and solid fuels by garbage and biomasses comprises a garbage unloading platform, a garbage sorting water pond, a slurry mixing pond, aloading platform and corresponding forming devices; the slurry mixing pond is used for preparing water-coal-slurry, and the forming devices are used for preparing the solid fuels. Therefore, the production process and equipment for producing slurry and solid fuels by garbage and biomasses can prepare the solid fuels and water-coal-slurry at the same time, and are relatively high in garbage treatment degree and garbage utilization ratio. In addition, garbage can be also fully treated.
