Dry milling




In 2014, the Ministry of Environmental Protection revised the “Emission Standard for Pollutants from the Ceramic Industry” (GB25461-2010) in advance, strictly regulating pollutant emissions from the building ceramic industry, and how to reform and innovate the traditional building ceramic industry with high emissions and high energy consumption. In the same industry at home and abroad, unremitting efforts are being made, and the new ceramic dry powder milling process has replaced the traditional ceramic wet powder milling process. It is widely accepted that a new process using green low carbon ceramic dry milling process will become The dominant direction for the preparation of building ceramic raw materials.
Agile Machinery is based on excellent processing equipment, more than 20 years of experience in ceramic industry raw materials equipment, and the concept of green low-carbon ceramic technology. It is committed to the research of new ceramic equipment and technology, and independently designs and manufactures crushers, granulators, and dryers. A complete set of ceramic powder production line for fluidized bed and other dry process equipment. The ceramic dry milling process and main equipment are as follows:

  • Primary and intermediate crushing systems for ceramic materials

(The size of the ceramic raw materials entering the factory varies. It is necessary to refine the primary and intermediate raw materials. It is conducive to the primary homogenization of the ceramic raw materials according to the formula and to prepare for the next process. We use: jaw crusher + agile machinery Small system of professional equipment roller crusher designed for ceramic industry)

  • Electronic batching system for ceramic raw materials

Different ceramic raw materials are processed into fine particles, which are automatically compounded and mixed according to the ceramic formula through the electronic batching system of the feeder; they are sent to the intermediate storage to prepare for the fine grinding of the powder.

  • Vertical grinding or Raymond machine fine grinding system
(Put the small granules in the middle storage bin according to the ceramic formula into the vertical mill system to obtain the fineness required by the ceramic process)

  • Ceramic material secondary homogenization system

(The secondary homogenization of the fine powder milled by the vertical mill is very important. It is an important link to ensure the stability of the ceramic formula. The fine powder is mixed and homogenized at different times in different silos to obtain a relatively stable ceramic formula system.)

  • Humidification granulator and dry fluidized bed equipment

The secondary homogenized ceramic fines are conveyed to the humidifying ceramic granulator through the conveying system, and the ceramic raw materials containing less than 5% water are humidified to 11% water and granulated, and then the dried fluidized bed is used to granulate 11% of water. The ceramic raw material evaporates to 6% of the ceramic granules containing water, and is sent to the aging warehouse, which is used by the press.

  • Humidification granulator and dry fluidized bed equipment
    (High degree of automation, using PLC automatic control system, and can realize remote control, easy operation and reduce labor costs)


    Practice has proved that the dry milling process fully meets the process requirements of ceramic presses. The significant features are low investment, low energy consumption, small floor area, high degree of automation, and fewer operators, which can significantly reduce equipment investment and product costs.
