Rпр= exp (6 - 0,05 ν2-0,09ν + 0,007 k1+0,03 k2)
где Rп р - давление прессования в МПа; ν - влажность пресс-порошка в %; K1 - содержание пылеватых частиц в %; K2 - содержание глинистых частиц в %.The method relates to the production of building materials, and more specifically to methods of manufacturing building bricks from low-quality raw materials. The solution is based on the task of creating a method of making bricks from loess-like silt with low energy intensity of the process, reduced requirements for the fractional composition of press powder and high stable quality of products. The method consists in the fact that the raw material is pre-crushed, dried, fine grinding of the dried raw material, moistening the press powder to a moisture content of 6 - 12% and two-stage pressing are carried out. Drying is carried out by the conductive method at a temperature of 300-400 ° C, fine grinding, mixing and moistening operations are carried out at the outlet temperature of the press powder after drying 300-400 ° C; determined by the formula:
R ave = exp (6 - 0,05 ν 2 -0,09ν + 0,007 k 1 +0,03 k 2)
where R p p - pressing pressure in MPa; ν is the humidity of the press powder in%; K 1 - the content of dust particles in%; K 2 - the content of clay particles in%.
