The invention discloses a solid waste crushing treatment device for machining. The solid waste crushing treatment device for machining disclosed by the invention is reasonable and simple in structure,low in production cost and convenient to mount. The solid waste crushing treatment device for machining disclosed by the invention is convenient to operate, quick to treat and time- and labor-saving.Solid wastes are placed in a concave chamber, a rolling motor drives a crushing hammer to crush the solid wastes, then the solid wastes are placed in a grinding chamber, a first motor drives a grinding roller to grind the solid wastes, the solid wastes enter a crushing chamber, a crushing shaft crushes the solid wastes which then enter a grinding chamber and are ground by means of the grinding roller, then the solid wastes enter an upper refining particle chamber, a grinding rotating rod grinds and refines the solid wastes, and the solid wastes are filtered by means of a filter screen, the solid wastes which are big in particle are continuously ground and refined by the grinding rotating rod, and finally, a pinch roller further refines the solid wastes. By means of the technical points, the solid wastes are crushed, and the solid waste crushing treatment device for machining is automatic in full course and high in efficiency.
