壓球機主要用于壓制難以成型的粉末材料，其特點是成型壓力大，主機轉數可調，配有螺旋送料裝置。壓球機又稱壓球機、礦粉壓球機、雙輥壓球機等。壓球機主要用于制造有色和黑色金屬礦粉的球塊，直接進爐冶煉，提高附加值。冶金行業所有廢棄物和輔助材料需要上爐的，都需要壓球機。如除塵灰、池泥、氧化皮、鋼渣、鐵精粉、鋁灰粉、硅錳礦粉等。是一種有效節約能源保護環境的產品。

       壓(ya)球(qiu)機(ji)工作原理:壓(ya)球(qiu)機(ji)主電機(ji)通(tong)(tong)(tong)(tong)過V帶(dai)傳輸(shu)到(dao)(dao)(dao)減(jian)速器:減(jian)速器通(tong)(tong)(tong)(tong)過聯軸器傳輸(shu)到(dao)(dao)(dao)主動軸，然后通(tong)(tong)(tong)(tong)過一對(dui)開式齒輪保證兩輥軸同步，其(qi)中(zhong)被動輥由液壓(ya)缸活塞(恒壓(ya)帶(dai)斜鐵)支撐，系統壓(ya)力由液壓(ya)回路、液壓(ya)控制(zhi)閥和(he)蓄(xu)能(neng)器支撐，物料(liao)(liao)(liao)通(tong)(tong)(tong)(tong)過定量設備通(tong)(tong)(tong)(tong)過儲料(liao)(liao)(liao)倉均(jun)(jun)勻(yun)進入成(cheng)型(xing)(xing)機(ji)料(liao)(liao)(liao)斗(dou)，通(tong)(tong)(tong)(tong)過料(liao)(liao)(liao)斗(dou)上的(de)調(diao)節閘板調(diao)節，使物料(liao)(liao)(liao)均(jun)(jun)勻(yun)進入對(dui)輥中(zhong)間。等速反向運(yun)行的(de)對(dui)輥壓(ya)縮物料(liao)(liao)(liao)的(de)單位成(cheng)型(xing)(xing)壓(ya)力由小(xiao)變大(da)，對(dui)輥中(zhong)線成(cheng)型(xing)(xing)壓(ya)力達到(dao)(dao)(dao)很大(da)值。物料(liao)(liao)(liao)通(tong)(tong)(tong)(tong)過線后，成(cheng)型(xing)(xing)壓(ya)力迅速變小(xiao)，使物料(liao)(liao)(liao)進入脫球(qiu)狀(zhuang)態(tai)，順利脫球(qiu)。
