目前,在有些腐植酸类产品的生产中,实际上已涉及到了风化煤参加的固—固反应问题。在腐植酸复混肥的生产中,有风化煤与有机肥料的混合过程,两种固体物料除了物理混合外,还有无我们所希望的化学反应过程?在腐钠生产中,湿法工艺的烘干成本高,有些厂采用了半干法工艺甚至想采用干法工艺,以尽量降低反应中的加水量,但降 At present, in some humic acid production, actually involved in the weathered coal solid-solid reaction problems. In the humic acid compound fertilizer production, weathered coal and organic fertilizer mixing process, in addition to the physical mixing of two solid materials, there is no chemical reaction process we hope? In the production of sodium, wet process Drying costs are high, some plants use semi-dry process even want to use dry process, in order to minimize the amount of water added in the reaction, but down
