Dynamic raw coal screening and crushing treatment system

The invention relates to a dynamic raw coal screening and crushing treatment system which comprises a screening roller used for screening materials, crushing rollers installed below the screening roller and a self-moving machine tail installed at the bottom end of a bridge type reversed loader. Two detection assemblies located on one side of a crushing roller correspondingly are installed in the crushing box, a plurality of roller tooth adjusting assemblies are installed on the crushing roller, and by the adoption of the roller tooth adjusting assemblies, when roller teeth are abraded, the roller teeth can be compensated through a compensation block, the situation that a gap between the two roller teeth is too large, and the service life of the roller teeth is prolonged is effectively avoided. And meanwhile, by matching with a reminding assembly, a reminding sound can be made when a compensation block is in a maximum compensation state, so that a worker is informed of replacing an adjusting roller tooth assem
