The invention relates to the field of crushers and in particular to a new-type efficient crusher. The new-type efficient crusher comprises a workbench, a supporting device installed at the top of theworkbench, a driving device installed on the side wall of the supporting device and a crushing device installed at the top of the workbench. The crushing device is in transmission connection with thedriving device. The crushing device comprises a material loading part, a crushing part and a material unloading part. The supporting device comprises two supporting components. The driving device comprises a driving component. The new-type efficient crusher is capable of, through pouring a material to be crushed from a material loading port, enabling the crushed material to pass through a sealed cylinder and performing rotation crushing through a plurality of crushing blocks, finally flowing into a material unloading cylinder from the bottom of the sealed cylinder, and guiding out the crushedmaterial. Because the surfaces of the crushing blocks and the inner wall of the sealed cylinder are sawtooth-shaped, the crushing effect is better. The sealed cylinder has the sound-insulating effect,and material loading and crushing can be continuously performed, efficiency is greatly improved.
