·ABB motor and spindle bearings use American Tim ken bearings; other bearings use SKF bearings；

·It is suitable for superfine grinding of shrimp feed and aquatic extruded feed;

·Vertical shaft without wire screen structure, crushing and grading are completed simultaneously;

·The main shaft bearing is air-cooled to overcome the high temperature caused by the high-speed and heavy-duty main shaft bearing operation;

·The side door with safety lock can easily replace and install the hammer and wear plate;

·The device with hydraulic lifting top cover can easily replace the ring gear;

·The crushing particle size is continuously adjustable from 60 to 200 mesh, 95% of the shrimp feed exceeds 80 mesh, and 85% of the puffing is expected to exceed 60 mesh.
