Overflow Vs Grate Discharge Ball Or Mill Why Retrofit

Jun 24, 2015 The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution.

Slurry Flow In Mills Gratepulp Lifter Discharge Systems

Abstract. Pulp lifters, also known, as pan lifters are an integral part of the majority of autogenous AG, semi-autogenous SAG and grate discharge ball mills. The performance of the pulp lifters in conjunction with grate design determines the ultimate flow capacity of these mills. Although the function of the pulp lifters is simply to transport the slurry passed through the discharge grate into the discharge trunnion, their performance depends on their design as well as that of the grate ...

Converting A Ball Mill From Overflow To Grate Discharge

Jun 23, 2020 The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge
