The invention discloses a grid plate and a crusher. The grid plate comprises a plate body, the surface of the plate body comprises a top face, a bottom face and two side faces, the top face is a plane, the bottom face is a curved face, the lengths of vertical lines from all positions on the bottom face to the top face are not completely the same, each side face comprises a base area and a protruding area connected with the base area, a boundary between the base areas and the protruding areas is a straight line and is parallel to the top face, the base areas are located between the top face and the boundary, the protruding areas are located between the boundary and the bottom face, and the protruding areas deviate from the middles of the base areas, so that the plate body is of an asymmetric structure. According to the grid plate, the asymmetric structure is adopted, the structural strength of the plate body is specifically enhanced, the grid plate is not prone to bending deformation due to abrasion in the usi
