本系列设备系引进日本样机经改进研制而成，具有高频疏解。磨浆、除砂多种功能，特别适用于全化学浆、半化学浆及再生浆的处理，具有纤维疏解完全、不破坏纤维，得浆率高，分丝帚化作用好等优点。使用该设备所生产的纸张抗拉强度高、匀度好、纸面光洁、平滑，是我国近几年来继打浆机、圆盘磨之后的新一代打浆设备。HGSJ Ⅱ型及Ⅲ型为卧式安装，HGLSIV为立式安装。
　　 Serial equipment department this introduce japanese prototype of a machine is it is it,high frequency discongested,rubed the thick liquid, got rid of sand many kinds of functions to develop to inprove, itsuitable fors to be  all chemical thick liquid,half treatment of chemical thick liquid and recycled thick liquid especially,have fibre discongest complete destroying fibring, gening thick liquid to be rate high dibiding into silk broom function advantaging such as being kind. The paper tensile strength of using this equipment to produce is high,even degree is good, the paper is bright and clean,level an smooth, our country  a new generation following pulling an oar machine,round mill pull an oar the equipment in recent years.HGSJⅡtype&Ⅲtype is horizontal installation,HGLS IV is vertical installation.
