3、和原料的含水率、成份以及水溫有關(guān)。Pulping:Beforepulping,youshouldweight,thenputtherawmaterialtobarrelofhydrapulperbymanualorconveyor,addsomewater,thenstartthemachine.Generally,thepulpingtimeis20-30minaccordingtothemoisturecontentofrawmaterialandwatertemperature.1.放漿:水力碎漿機(jī)制好的漿通過機(jī)器底部的放漿閥直接排放到濃/配漿池或由連接在放漿管上的漿料輸送泵
