に機械加工して制御部を設けている。A control for controlling the flow of the mixture of the object to be treated and the medium into a plug flow when the rotary cylinder is rotated on the entire peripheral surface of the tank wall (13) and / or the rotary cylinder (3). The part (14) is formed. The plug flow is a flow in which the whole moves at almost the same speed except for the vicinity of the wall surface and the speed gradient becomes 0. Therefore, the control unit (14) has an axial velocity distribution from the inlet to the outlet. It is preferable to be able to regulate so as to be in a state substantially as shown by the arrow in FIG.
For example, in the rotary cylinder shown in FIG. 1, a groove for forming a right-hand thread and a groove for forming a left-hand thread are intersected with each other on the peripheral surface of the cylinder wall to form a minute projection having a quadrangular cross section in the remaining portion. The machine is machined to provide a control unit.

形成するとよい。The control unit of the rotary cylinder shown in FIG. 4 has a groove extending parallel to the axis of the rotary cylinder as if it were a spur gear tooth groove and a screw groove extending obliquely with respect to the axis. This is an example in which a minute protrusion having a quadrangular cross section is machined by providing an oblique groove to be formed. At this time, the threaded groove may be formed by inclining in a direction of returning the mixture to the supply port side when the rotary cylinder rotates.

れた。In the above embodiment, the protrusion is formed integrally with the cylindrical wall by machining, but it may be formed integrally by the lost wax method or another casting method. The protrusions may be formed in an oval shape, a circular shape or any other suitable shape, or may be formed on the inner wall of the tank. Further, the control unit may be a recess instead of the protrusion. If the pitch of such protrusions is made fine and properly arranged, the mixture of the object to be processed and the medium can be made to flow in a plug-like flow state substantially as shown by the arrow in FIG. When the height of the protrusion was set to about 4 mm and the width of the processing space (2) was set to about 4 mm corresponding to the size of about four media or more, an experiment confirmed that the plug flowed state. Was given.

媒体分離手段を通って吐出口(6)から吐出される。The wet medium dispersion device of the present invention is constructed as described above, and is supplied from the supply port (5) between the rotating cylinders in the processing tank (1) at an appropriate feeding pressure by a pump (not shown). The object to be processed is immediately mixed with the medium and flows into the processing space (2). Then, the rotation of the rotary cylinder (3) causes the mixture to flow through the processing space (2) as if it were in a plug-like flow state, and during this period, the mixture uniformly circulates around the plurality of rotary cylinders (3) and (3), In some cases, a uniform shearing force is sufficiently applied to the object to be processed, the object to be processed is dispersed, and is discharged from the discharge port (6) through the medium separating means.

処理され、装置を小型化することもできる。The present invention is constructed as described above, and the flow of the mixture of the medium and the object to be treated is almost plug-like (plug flow).
Since the axial velocity gradient of the mixture from the inlet to the outlet of the treatment tank is reduced, the chances of collision between the media increase due to the circulation of multiple rotating cylinders. A uniform shearing force is applied to the object to be processed over the entire tank, which is 2
Although it is a short time of 1/3 to 1/3 or less,
A fine crushed product can be obtained and its particle size distribution is sharp.
You can get good things. Further, since the temperature control fluid such as cooling water is circulated directly to the cylinder wall of the rotary cylinder, the efficiency of heat exchange is good. Moreover, since a plurality of rotary cylinders are arranged in parallel, the processing space is continuous and The processed product is dispersed and processed through a long path, and the apparatus can be downsized.
