The invention relates to a powder spraying device capable of repeatedly utilizing raw materials for ceramic production. The powder spraying device comprises a shell. The shell is provided with a movable door, an inclined plate is arranged in the shell, one end of the inclined plate stretches out of the shell, a vibration motor is arranged below the end, stretching out of the shell, of the inclinedplate, and the shell is divided by the inclined plate into a powder spraying chamber and an installation chamber in sequence from top to bottom. Multiple rotating motors are arranged in the installation chamber, the rotating motors are connected with placing tables through rotating rods, cleaning devices are symmetrically arranged below the placing tables, the centers of the placing tables are located on the same straight line, the powder spraying assembly comprises a powder barrel, a powder outlet at the bottom of the powder barrel is connected with a first powder supply pipe, the lower endof the first powder supply pipe is connected with a second power supply pipe, multiple powder spray heads capable of spraying powder to the placing tables are arranged in the second powder supply pipe, and the lower end of an inclined plate in the powder spraying chamber is provided with a powder outlet. Powder spraying is comprehensive, the powder spraying efficiency is high, powder can be recycled, and the cost is saved.
