| description | The utility model relates to a jaw crusher. A steel plate which has a thick upper part and a thin lower part is additionally arranged on the surface of a fixed jaw plate, so that the opening angle of the crushing cavity is reduced to be 15-20 degrees, and compared with the opening angle, being more than 25 degrees, of the existing jaw crusher, the feeding speed and the discharging smoothness can be obviously improved, the production efficiency can be increased by more than 10%, the discharge stopping or the material residue in the crushing cavity can be basically eliminated, the number of the small crushed stone particles is obviously increased, the quantity of sand particles with the grain size of 1-2mm is promoted by 20-30%, the crushing effect is remarkably promoted, and the jaw crusher can establish a good base for the subsequent machine-made sand production. |
