主要原料:桐碱、棉籽灰等。主要设备:反射炉、蒸发灶、干炒灶、铁坦克、打粉机、马达、大缸。制造过程:我国含钾盐植物很丰富,象桐子壳、棉子壳、蒿麦、棉箕、豆箕、向日葵、茶子壳等比较含钾盐多,而其他草木灰也含有不同程度的外盐,现在把土制碳酸钾、硫酸钾、氯化钾的操作情况简述如下: The main raw materials: Tong Cao, cottonseed ash and so on. The main equipment: reverberatory furnace, evaporation stove, dry cooking stove, iron tank, powder machine, motor, large cylinder. Manufacturing process: China’s potassium-bearing plants are very rich, such as Tongzi shell, cotton shell, Artemisia oleracea, cottonseed meal, soybean meal, sunflower, tea seed shell and other relatively more potassium, and other ash also contains varying degrees of external salt The operating conditions of the indigenous potassium carbonate, potassium sulfate, and potassium chloride are briefly described as follows:
