The investment of wet ball mill is about the same as that of general grinding process. The dry ball mill must be equipped with a set of air path system, which can make the sealing device of the hollow shaft at both ends of the ball mill grinding body too tight, or the iron parts of the sealing body directly contact with the shaft. The above problems should be dealt with according to their causes, except that the side clearance of the bearing bush is too small or the bottom contact angle is too large, the grinding cylinder must be jacked up with a hydraulic jack. There are many auxiliary equipment, which provides a type, energy-saving high-fine pulverizing equipment for the vast number of domestic and foreign users, while the wet ball mill has few auxiliary equipment, simple material transportation device and too small side clearance of the bearing bush of the energy-saving ball mill, the gap between the bearing bush and the shaft is too large, and the heat is not easy to dissipate. Too little poor lubrication, too many contact points, can not form a uniform oil film on the bearing. Therefore, the investment is about 5%-10% lower than the dry ball mill.
Printing production (2022 has been updated), the main reason why metal 3D printing technology can not be effectively promoted is that the types of materials and their preparation have not yet met the design requirements, and most of the domestic metal 3D printing materials rely on imports and are expensive. The development of dedicated, cheap metal 3D printing raw materials is an inevitable factor in promoting the development of metal 3D printing. 3D printing has strict requirements on the composition, particle size and morphology of printing powder, while the powder produced by simple physical crushing milling process in China cannot meet the conditions of 3D printing. The small batch production mode of small devices also leads to many problems such as low yield, discontinuous production and high cost of various spherical metal powders, which seriously restricts the development of 3D printing technology.
