体の共粉砕の際には固体と液体の分解を良くする
ため液体の添加は断続的或いは連続的に添加し、
添加を終了した後も一定時間粉砕が行われる。 Co-pulverization of solids and liquids using vibration mills, ball mills, etc. is widely used to produce various catalysts and ceramic raw materials. When co-pulverizing solids and liquids, add the liquid intermittently or continuously to improve the decomposition of the solids and liquids.
Grinding continues for a certain period of time even after the addition is complete.

が付着し開口部が閉塞するという問題があつた。 After this liquid is added intermittently or continuously, the opening inside the pulverizer for adding the liquid during pulverization is not filled with liquid, and the remaining liquid is leaking, so it may not be possible during pulverization. There was a problem in that the openings were blocked by the rising solids.

つた。 In order to solve this problem, there is a method of charging inert gas after charging the liquid, but it is not effective unless the inert gas is constantly flowing in. In addition to the cost of inert gas, There have been problems in that solids and/or liquids are also lost from the mill, resulting in lower yields and changes in the ratio of solids and liquids.

る。 The present invention has a time period in which solids and liquids that exhibit adhesive properties when they come into contact with each other are crushed by adding the liquid intermittently or continuously without charging the liquid in batches. In the method of crushing,
The liquid is charged into the crusher using a nozzle having an opening, and when the liquid is not charged, the opening of the nozzle is closed at the tip, thereby preventing the crushed solid from adhering to the opening. This is a method of charging liquid to a crusher. The present invention also provides a nozzle for charging liquid into a pulverizer, which has an opening 1 at the tip of the narrowed part 6 of the nozzle inserted into the pulverizer, and has a pin 2 inside to close the opening 1. Regarding.
本発明において適用される粉砕は格別限定はな
くボールミル、遠心ミルなどの微粉砕機に適用す
ると効果が大である。 The pulverization applied in the present invention is not particularly limited, and is most effective when applied to a fine pulverizer such as a ball mill or a centrifugal mill.

程度までの粉砕に適用すれば効果が大である。 In the present invention, the pulverization is dry pulverization, and the method of the present invention has almost no effect in wet pulverization in which the amount of liquid is much larger than that of solid. The ratio of liquid to solid is not particularly limited as long as it is suitable for dry pulverization, but it is usually most effective if it is applied to pulverization in which the liquid and solid are in approximately equal amounts.

によつては液状の無機化合物などが挙げられる。 As is clear from the purpose of the method and apparatus of the present invention, there are no particular restrictions on the solids and liquids to be crushed, but it is preferable to crush solids and liquids that exhibit adhesive properties when they come into contact with each other. It is highly effective when applied to the production of catalysts or their precursors, or the production of mixtures of ceramic powder and binder, where the ratio of liquid to solid needs to be controlled within a narrow range. Specific examples include solids such as oxides such as alumina and silica, metal hydroxides, and metal salts, liquid organic compounds, and in some cases liquid inorganic compounds.
本発明は液体の装入ノズルに特徴がある。即ち

液体を装入することができなくなる。 The present invention is characterized by the use of a nozzle with a structure in which the opening is closed at the tip of the nozzle, and the introduction of liquid is simply stopped by operating a valve, etc., and the introduction of liquid is stopped with the opening opened inside the crusher. When charging is stopped, fine solid powder adheres to the liquid remaining in the opening, further blocking the opening and making it impossible to charge the liquid next time.

端の開口部を閉じるのが好ましい。 There are no particular restrictions on the method of closing this opening, but it is effective to attach a lid to the opening or insert a plug-like object that tightly fits into the opening. At this time, it is a good idea to remove as much liquid as possible near the opening, for example by installing a valve on the liquid charging line outside the crusher, and after closing the valve, any remaining liquid from the valve to the nozzle opening should be removed. It is preferable to charge the powder into the pulverizer with an inert gas and then close the opening at the tip of the nozzle.
