Subject of Patent:
With the invention, which is the subject of a patent, a new system has been developed for the body mud preparation process by using different raw materials, which is one of the most important stages of ceramic tile production. With the invention, the following technical and economic advantages are provided in the ceramic production process:
• With the new system developed and patented, it was ensured that ceramic clays were produced in a targeted narrower size range and homogeneously (RRSB= d' and n parameters).
• With the developed system, significant savings were achieved in energy consumption. The grinding energy value, which is 36 kWh/ton on average in the existing systems, has been reduced to 19 kWh/ton in the new system; advantages were achieved in terms of both energy saving and sustainability.
• A significant reduction (35%) was achieved in the maintenance and operating costs of the systems.
• In view of its positive effects on the following ceramic production process, 8-10°C reductions were achieved in the firing temperatures of ceramic kilns. Considering the kiln speed and the reduced total firing time, a capacity increase of around 15% and savings in natural gas consumption are achieved.
• The firing behavior of the mass prepared in the new system is much more homogeneous and its melting point is stabilized at 1176-1178 C. The fluctuation in the range of 1180 – 1262 C has been eliminated in the existing systems, and this provides important technical and economic advantages by eliminating the different problems caused by the final product size and firing differences.


Summary of the Invention:
The invention consists of at least one, which is connected in series with each other via mill inlets (2.a) and mill outlets (2.b), rotates around a rotation axis (A) and is configured to transfer the material they grind from one to another in a flow direction (FD). two continuous mills (2), balls (B) in the amount and size that can move with the rotation of the mill (2) around the rotation axis (A) in the inner volume of the mills (2), to feed the material to be grinded to the first mill (2) in the flow direction (F). It relates to a grinding system characterized in that it contains a feed tank (1) connected to the mill and the diameter of a mill (2) in the downstream (FD) direction is larger than the diameter of another mill (2) in the downstream (FD) direction.
