Способ относится к области строительных материалов и включает подготовку сырья до достижения максимальной крупности кусков 40 - 60 мм, его сушку до влажности на 3 - 10% ниже критической для конкретного сырья, обработку сырья в стержневой мельнице до получения пресспорошка следующего фракционного состава: 0,25 мм - 30 - 60%; 0,25 - 2 мм - 35 - 65%; 2 - 3 мм - 2 - 25%. Прессование сырца производят при давлении 25 - 45 МПа, причем в течение 0,5 - 6 сек доводят давление до 12 МПа с дальнейшим достижением до максимального значения за 0,1 - 2 сек и выдержкой при нем в течение 0,1 - 3,5 сек, сушку сырца ведут при начальной температуре 30 - 60°С и конечной 80 - 160°С, а обжиг - при максимальной температуре на 20 - 250°С ниже температуры начала оплавления.The method relates to the field of building materials and includes the preparation of raw materials until the maximum grain size of 40–60 mm is reached, drying it to a moisture content of 3–10% below critical for a particular raw material, processing the raw material in a rod mill to obtain a press powder of the following fractional composition: 0.25 mm - 30 - 60%; 0.25 - 2 mm - 35 - 65%; 2 - 3 mm - 2 - 25%. Compaction of the raw material is carried out at a pressure of 25–45 MPa, and the pressure is adjusted to 12 MPa within 0.5–6 seconds with further reaching the maximum value in 0.1–2 seconds and holding it for 0.1–3.5 seconds. sec, drying of the raw material is carried out at an initial temperature of 30–60 ° C and a final temperature of 80–160 ° C, and firing at a maximum temperature of 20–250 ° C below the temperature of the start of melting.
