[0002] The raw material is placed in the sand making machine barrel through the conveying device, and then the barrel is driven to rotate through the transmission device. The grinding media are lifted to a certain height, and then fall under the gravity of the grinding media, so that the grinding media fall at a certain linear speed. The material is impacted, ground and extruded under the action of force, so that the material is finely ground.
