NOVELTY - Producing environmental friendly synthetic coal comprises: (i) manually screening the municipal solid waste; (ii) conveying to a double-roll asynchronous broken dismantling machine to break waste; (iii) screening primarily broken waste with a cylindrical sieve screening machine and separating stones, sundries, broken glass and earth blocks bigger than the hole diameter of mesh; (iv) grinding resulted waste; (v) transmitting the resulted waste and stirring with e.g. coal dust and slag powder, slurry and additive; and (vi) squeezing to shape comprehensive coal powder original material.    USE - The method is useful for producing environmental friendly synthetic coal.    ADVANTAGE - The synthetic coal has high combustion value, exhibits non-toxic gas and is economical and environmental friendly.    DETAILED DESCRIPTION - Producing environmental friendly synthetic coal, comprises: (i) manually screening the municipal solid waste, picking out big stones and wood sheets to separate primarily; (ii) conveying the resulted material by a mechanization conveyance method, and conveying continuously to a double-roll asynchronous broken dismantling machine to break the waste, distributing the sharp breaking stings to puncture the packed or blocked waste on circular faces of the two rollers of the machine, and primarily scattering the waste by a waste bag block filled with waste, and then separating and collecting the light waste materials e.g. plastics and paper through wind power and conveying to the production line part to process; (iii) screening with a separator, screening the primarily broken waste with a cylindrical sieve screening machine, separating stones, sundries, broken glass and earth blocks bigger than the hole diameter of the mesh through the rolling of the cylindrical sieve screening machine, while useful waste with the diameter smaller than the mesh drops on the industrialization conveyance equipment below the cylindrical sieve screening machine, conveying the stones, sundries and broken glass left in the cylindrical sieve screening machine spins continuously by a cylindrical sieve screening machine having a specific leaning angle, gradually slide to the outlet of the equipment and drop to another industrialization conveyance equipment outside the production system, and then adopting a strong electromagnet on the equipment for magnetic force separation and separating the iron material by strong electromagnet; (iv) grinding the waste, which is separated in the above process with a cutter type rotary grinder to particles, and conveying to next process with industrialization conveyance equipment; (v) transmitting the waste, which is ground to fine particles with a universal stirrer by industrialization conveyance equipment, and stirring with the ground original coal dust, coke slag powder, slurry, additive, bonding agent and deodorant, and then transmitting by the industrialization conveyance equipment and obtaining the coal powder of the environment-friendly synthetic coal; and (vi) squeezing to shape the comprehensive coal powder original material, which is stirred with a stirrer as the original material confection and the coal squeeze shaping machine is set with squeezing molds of different kinds and specifications to mold coal with different sizes and specifications.
