Refractory Brick molding machine pressure and the characteristics of the material is closely related to the properties of dried clay and using a mobile phone press forming of sludge water content is low, must use high molding pressure make the sludge particle rearrangement, pressurized mud is expected to occur elastic deformation and brittle deformation, out of the air side by side, in mechanical friction, electrostatic attraction and bonding force to a combination of, Mud particles combine with each other to form a body. For different mortar, due to the different shape of firebrick particle, water content, fine powder and binder, the degree of these forces are different.
Therefore, the properties of each kind of clay should be taken into full consideration when making refractory brick forming system.
Theoretically, refractory brick forming pressure is mainly composed of the following two parts: one is to overcome the friction between the sludge particles inside the required pressure: the second is to overcome the mud materials required of the external friction between mould pressure, due to the actual production of refractory clay partly due to the inhomogeneity of material properties, the molding pressure must also have a certain safety factor, and will pass this force is called to pressure.
In fact, it is difficult to calculate the pressure of refractory bricks mentioned above, so the total pressure needed for molding can only be determined approximately through experiments or according to experience, and it should be adjusted at any time in production according to the nature of concrete mud, equipment conditions, weather conditions, so as to form high-quality refractory bricks.
