Description

Dry classification powder making equipment for ceramic body powder

Technical Field

The utility model relates to a building ceramic production facility technical field especially relates to a dry process classification powder process equipment of ceramic body powder.

Background

The preparation of the ceramic green body generally comprises the steps of preparing materials according to the raw material formula proportion of the green body, preparing powder with corresponding particle size from the raw materials of the green body through a powder making system of a ceramic tile production line, and finally obtaining the ceramic green body through a material distribution and pressing system.

At present, in a ceramic tile production line, a powder making system of green body powder is generally a wet powder making system, and specifically, the working process of the wet powder making system mainly comprises the steps of adding water into a prepared green body raw material, putting the prepared green body raw material into a ball mill, carrying out wet ball milling to prepare slurry, and then carrying out spray granulation on the slurry through a spray tower to prepare the powder. In the existing wet milling system, the moisture of the slurry ball-milled by the ball mill is generally controlled to be 33-37%, and during the process of preparing the powder with the moisture content of 6-8% by spraying and granulating the slurry with the high moisture content by a spraying tower, higher heat is inevitably needed to evaporate the moisture, so that the energy consumption of the wet milling system is extremely high.

In order to effectively reduce the energy consumption in the powder process system, some manufacturers of architectural ceramics begin to research a dry powder process system to replace the existing wet powder process system with higher energy consumption. Specifically, the dry milling system comprises a dry mill, a granulator, a de-ironing machine, a crusher, a dry mill, a screen, a filter, a de-ironing machine, a granulator and a granulator. Compared with the traditional wet powder process system, the comprehensive energy consumption of the dry powder process system can be reduced by 60-75%, but the following defects exist:

firstly, the requirement for the moisture content of the green body raw material is high. In the existing dry powder-making system, the moisture content of the green body raw material is generally required to be within 15%, and the lower the moisture content, the more energy is saved. The method is characterized in that in the vertical grinding process of the dry type vertical grinding machine, redundant moisture in the blank raw material is evaporated mainly in a heat exchange mode, and if the moisture content of the blank raw material is too high, the vertical grinding machine needs to consume more heat, so that the energy consumption is increased, and the yield of the vertical grinding machine is influenced; and due to the limitation of equipment, the wall adhesion can easily occur in the vertical grinding machine after long-term use, so that the cleaning frequency of the vertical grinding machine has to be increased, the yield of the vertical grinding machine can also be influenced, the vertical grinding effect of fine powder can also be influenced by the wall adhesion phenomenon of the vertical grinding machine, and the fine powder can not meet the production requirement easily.

Secondly, the requirement on the iron oxide content of the blank raw material is high. The method is limited by the equipment composition of the existing dry powder making system, the iron removal capacity of the system is poorer than that of the traditional wet powder making system, and meanwhile, in order to ensure the production efficiency of the green body, the treatment capacity in the process of one-time powder making is generally larger, so that in order to ensure the iron removal effect of the green body raw material, the iron oxide content of the green body raw material is generally required to be not too high, otherwise, the whiteness of the fired ceramic green body product is poor, the defects of miliaria, pinholes and the like are easily generated on the surface of the product, and the product quality of the green body is reduced.

The requirement on the organic content of the blank raw material is high. At present, the method is limited by the equipment composition of the existing dry powder making system, and the capability of removing organic matters is poorer than that of the traditional wet powder making system, so that residual organic matters are remained in the blank to form a black core, and the method is not favorable for stabilizing the quality of the finished product of the ceramic blank.
