[0002] The new sand making machine (vertical shaft impact crusher) is suitable for crushing soft, medium-hard and extremely hard ore materials with a hardness not exceeding 320Pa. Sand making machines are widely used in many departments such as large-scale, smelting, building materials, highways, railways, water conservancy and chemical industries. When working, driven by the motor, the rotor rotates at a high speed, and the material enters the first crushing chamber and impacts and crushes with the rotor's plate hammer, and then enters the second crushing chamber for crushing. In the crushing process, not only is the impact crushing between the material and the plate hammer and the liner formed, but also the stone-to-stone shaping between each plate hammer and the crushing chamber is completed. Finally, it is discharged from the discharge port.
