How HPGRs compare to conventional milling

Aug 19 2019 Within comminution circuits High Pressure Grinding Rolls HPGR are increasingly replacing conventional SAG rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40 less energy than traditional reduction methods but their wearable

High pressure suspension mill High pressure mill High

It has the same working principle as Raymond Mill but its grinding device is fixed with 1000 - 1500 kg pressure springs. When the machine works the grinding roller under the action of high pressure spring and centrifugal force rolls close up to grinding ring its rolling pressure is 1.2 times higher than that of Raymond mill given an identical condition and its output may increase 20 to .
