Abstract

PURPOSE:To reduce the opening and closing frequency of the cover of a ball mill by a method in which while each slurry of raw ores, clay, returning soil, etc. is controlled by a flow amount-detector and a control valve, said materials are introduced into a mixing tank with water in a prescribed ratio so that the compounding ratio of each raw material becomes a prescribed ratio in the conversion into dry weight, and they are agitated and mixed there. CONSTITUTION:Raw ores (feldspar, silica, porcelain stone, alumina, etc.) are thrown into a ball mill 1 with water and are crushed by wet method until prescribed grain size is obtained. Returning soil, auxiliary raw material, clay, etc. are respectively dissolved in each tank 7, 8, 9 and are prepared in slurry state, and then they are sent into a mixing tank 11 with water by the pump 10 provided in each tank. Then the flowing amount of each raw material is exactly measured by the flowing amount- detector 12 of e.g. electromagnetic type, and is controlled by the control valve 13 of e.g. electromagnetic type linked to said detector 12. Each slurry is introduced into the mixing tank 11 so that the prescribed compounding ratio of the raw materials is obtained in the conversion into dry weight. The water in each raw material and the mixing ratio thereof are computed by a microcomputer, etc. and are controlled thereby. Said materials are uniformly agitated and mixed in the mixing tank 11.

However, in such conventional mixing methods, it is necessary to stop the ball mill (1) and open and close the lid every time auxiliary raw materials or clay are added, which is time-consuming and also generates dust when adding dry clay. The disadvantage was that the working environment deteriorated. In addition, in the conventional method, since the raw materials are fed one after another into the same ball mill (1), the amount of raw ore that can be initially fed into the ball mill Il+ is small, and many ball mills
There was a drawback that it was necessary.

Also in the present invention, raw stone (feldspar, silica stone, pottery stone, alumina, etc.) is first put into the ball mill 11) together with water,
It is wet-milled until it reaches a predetermined particle size. A small amount of clay was then added into the ball mill +11 to prevent settling.
The raw stone slurry is mixed by rotation, and then sent to the raw stone slurry tank (6) by, for example, blowing air.

Furthermore, in the present invention, returned soil, auxiliary materials, clay, etc. are also dissolved in the respective tanks (7), (8), and (9) and prepared as a slurry. Each slurry of auxiliary raw materials, clay, etc. is sent together with water to a mixing tank aD by a pump O1 attached to each tank. At this time, the flow rate of each raw material is accurately measured by, for example, an electromagnetic flow rate sensor suitable for measuring the flow rate of slurry fluid, and is controlled by an electromagnetic control valve that is linked to this. The slurry is led to the mixing tank 00 so that the raw materials have a predetermined mixing ratio in terms of dry weight. Note that the moisture content and mixing ratio of each raw material are calculated and controlled by a microcomputer or the like. These are uniformly stirred and mixed in the mixing tank OD to form a slurry, which is stored in the storage tank 0 tatami. The mixed slurry raw material in the storage tank Oa is dehydrated using a dehydrator such as a filter press, as is conventionally known, and sent to the subsequent molding process, as in the past.

(Effects of the Invention) As explained above, the present invention prepares each slurry of raw stone, clay, recycled material, etc. in each tank, and controls each slurry with a flow rate detector and a control valve, while each raw material is Since the raw stone slurry, clay, auxiliary materials, and water are mixed in one ball mill, the raw ore slurry, clay, auxiliary materials, and water are mixed together with water in a predetermined ratio in a mixing tank in order to obtain the predetermined mixing ratio in terms of dry weight. Compared to the conventional method, the frequency of opening and closing the lid of the ball mill can be reduced, and the generation of dust associated with this can be prevented. In addition, since clay and other substances are not added or mixed in the ball mill, the amount of raw ore that can be crushed can be increased by 1.5 to 2.0 times compared to conventional methods, and the mixing ratio of each raw material can be adjusted freely using flow rate detectors and control valves. Alternatively, bases of various compositions can be made. Therefore, the present invention greatly contributes to the development of industry as a method for preparing ceramic raw materials that eliminates the conventional problems.
