The invention discloses a novel chemical material screening machine. The novel chemical material screening machine comprises a pre-screening box, a screening machine body and support frames. The support frames are arranged on the left and right sides of a fixed base. The two groups of support frames are connected with the left and right sides of the screening machine body. An electric box is arranged on the right side of the screening machine body. A vibration motor is arranged inside the electric box. The front end of the vibration motor is connected with the right side of a mounting plate through a rotating shaft. A vibration screening plate B and a vibration screening plate A are correspondingly arranged at the upper and lower ends of the mounting plate. A pushing plate is arranged at the lower end of the screening machine body. A handle is arranged on the surface of the pushing plate. The upper end of the screening machine body is connected with the lower end of the pre-screening box through a material outlet. According to the novel chemical material screening machine, through a fan installed on the left side of the pre-screening box, since the right side of the pre-screening box is connected with an impurity box through a partition and since an empty groove is formed in the upper end of the partition, dust or light floating impurities in chemical materials can be blown into the impurity box, and the novel chemical material screening machine is more practical and suitable for wide application and popularization.
