PURPOSE:To form a large number of uniform particles, by injection a substance to be treated from a large number of small holes bored in the fixed side wall of a hermetically closed chamber along with gas by utilizing pressure difference across said side wall and, at the same time, intermittently blocking said small holes. CONSTITUTION:A liquid 14 to be treated in a storage tank 11 is sucked up to the end of a pipe 12 and a motor 5 is driven to rotate a rotary disc 6. The liquid 14 to be treated at the end of the pipe 12 is sucked in a pump chamber 8 by the rotation of a sucking pump blade 10 to reach small holes 7 through fine grooves 9 by centrifugal force to be adhered as a membrane. When a hermetically closed chamber 2 is filled with compression air through a pressure air pipe 13 and the small holes of the rotary disc 6 during rotation positionally coincide with that of the fixed side wall 1a of said chamber 2, compressed air is injected through the small holes to inject the membrane of each small hole 7 to the outside of the apparatus main body 1. When the rotational speed of the rotary disc 6 increases, the outside of each small hole 3 comes to an ultrasonic region. |
