Description

Roller press for solid waste Technical Field The invention relates to the technical field of roller presses, in particular to a roller press for solid waste. Background Cement is a powdery hydraulic inorganic cementing material, which is formed into slurry after being added with water and stirred, can be hardened in air or hardened in water, and can firmly bond sand, stone and other materials together, the ingredients of the cement are limestone powder and clay, the limestone powder and the clay are required to be mixed in the production process, raw materials are wasted, the cement can be manufactured by normal building demolishment and other residual solid wastes, but the existing feeding system cannot crush the solid wastes, the manufactured cement contains a lot of granular impurities of the wastes, the adhesion is poor, the cement is easy to fall off, the size of the solid wastes is different after crushing the solid wastes, the space between crushing rollers is difficult to accurately adjust when the solid wastes are crushed by rolling, and the crushing effect is influenced by targeted rolling.
