目前大多數企業球磨機存在啟動困難、運行效率低、研磨時間長、單位電耗高等缺陷。宋陵礦山機械有限公司開發的開關磁阻節能電機調速系統，可以替代現有的普通電機或滑差調速電機，以達到降低成本，提高效益的效果。
為了(le)解(jie)決(jue)球磨(mo)機(ji)(ji)的(de)(de)(de)(de)啟(qi)(qi)動(dong)(dong)問(wen)題(ti)，普通(tong)電(dian)(dian)(dian)(dian)機(ji)(ji)通(tong)常采(cai)用星-三角啟(qi)(qi)動(dong)(dong)方(fang)式(shi)同時增大電(dian)(dian)(dian)(dian)機(ji)(ji)容(rong)量，而正(zheng)常運轉后電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)(de)(de)(de)負(fu)載(zai)小(xiao)于電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)的(de)(de)(de)(de)額定(ding)(ding)負(fu)載(zai)，造成大馬拉小(xiao)車的(de)(de)(de)(de)現象，能(neng)源浪費大。采(cai)用星-三角啟(qi)(qi)動(dong)(dong)方(fang)式(shi)時因(yin)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)所帶負(fu)荷(he)很(hen)大，導致電(dian)(dian)(dian)(dian)機(ji)(ji)啟(qi)(qi)動(dong)(dong)時非常困難(nan)，往往要(yao)經過幾次啟(qi)(qi)動(dong)(dong)，使球磨(mo)機(ji)(ji)形成一定(ding)(ding)貫性后才(cai)能(neng)啟(qi)(qi)動(dong)(dong)起來(lai)。而且啟(qi)(qi)動(dong)(dong)電(dian)(dian)(dian)(dian)流非常大，對電(dian)(dian)(dian)(dian)網(wang)沖(chong)擊危害嚴重，有時會發生(sheng)燒壞接觸器、電(dian)(dian)(dian)(dian)路、電(dian)(dian)(dian)(dian)機(ji)(ji)等現象。并對機(ji)(ji)械部分造成沖(chong)擊，減少設(she)備的(de)(de)(de)(de)使用壽命。給企(qi)業正(zheng)常生(sheng)產帶來(lai)一定(ding)(ding)威脅并造成不應有的(de)(de)(de)(de)經濟損失。采(cai)用滑(hua)差調速(su)電(dian)(dian)(dian)(dian)機(ji)(ji)解(jie)決(jue)了(le)啟(qi)(qi)動(dong)(dong)難(nan)的(de)(de)(de)(de)問(wen)題(ti)，但滑(hua)差調速(su)效率低、設(she)備維護量大給用戶使用造成能(neng)源浪費大、維護困難(nan)等問(wen)題(ti)，不能(neng)很(hen)好解(jie)決(jue)球磨(mo)機(ji)(ji)的(de)(de)(de)(de)現實問(wen)題(ti)。更多詳情請咨(zi)詢(xun)：0371-64373366
