Description
本发明涉及碎磷矿石团块的制造方法，特别是碎磷矿石团块的制造方法。
制造碎磷矿石团块的方法有塑造法、烧结法和压块法。前两种方法均需1100℃以上的高温烧结，耗能较高，压块法是将磨细的磷矿与粘结剂（例如水玻璃、粘土或水泥）混合，压成团块后，或在大约750℃的温度下灼烧，或用水保养固结（水泥作粘结剂时）。前者耗能较高，后者制成的团块入炉后在高温下会破碎。
本发明的目的，在于提供一种磷矿石团块的制造方法。本方法成本较低，耗能较小，制成团块稳定性好。
本发明是在100份粒度小于5毫米（其中应有不少于20%的粒度小于1毫米）的磷矿石中，加入0.5至3份腐植酸类粘结剂（以干基计），以及3至14份水（指各组分所含水量的总和）。经搅拌器搅拌，用对辊成型机或其它成型机在大于200千克重/（厘米）2的压强下成型，团块经150℃至300℃温度下烘干至团块所含水分在0.3%以下即可。
腐植酸类粘结剂可以是腐植酸的一价碱金属盐、腐植酸铵或煤碱剂。一般以2～4%的浓度加入，其加入量和磷矿石团块的强度一般成正比，由于腐植酸一价碱金属盐的表面活性作用，有助于使仅有的水份得到均匀分布和有效润湿矿粒表面，并可减小矿粒之间摩擦，增加其间滑动能力，使成型压力能够均匀传递，使团块更为质密均一，强度较高。
加入水量的大小对团块质量有重大影响，大时，团块强度低，不易脱模;小时，不易均匀地润湿矿粒表面，造成强度下降，成品率低。
本发明和已有技术相比，粘结剂易得，耗能较小;制造的磷矿石团块成本较低，反应活性好，基本不掺入有害杂质，冷抗压强度大于50千克重/（厘米）2，从2米高度跌落到水泥地面不破碎，热稳定性好，可作生产黄磷、钙镁磷等产品的入炉原料。
实施例：
100份重量的磷矿石（粒度小于1毫米的＞20%，1～2.5毫米的28%，2.5～小于5毫米的18%，水份1%），1份重量的腐植酸钠，加入13份重量的水，混合均匀，用柱塞式压模机，在300千克重/厘米2压强下成型;分别在200℃、600℃、800℃、900℃温度下加热半小时，团块的冷抗压强度为54千克重/厘米2、38千克重/厘米2、85千克重/厘米2、98千克重/厘米2，从2米高度跌落到水泥地面不破碎。
