An overfilling indicator for wet overflow ball mills

This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions. Mathematical descriptions of the method to estimate the volume-based residence time of slurry are presented.

Overflow VS Grate Discharge Ball or Mill Why Retrofit

2015-6-24  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.

Ball Mill Working Principle And Main Parts

2015-7-14  The most widely used in the production of a variety of ores are wet overflow ball mill and wet grate ball mill. Aside from common ball mills there is a second type of ball mill called planetary ball mill Planetary ball mills and The grinding balls. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes.

What are the Differences Between Dry and Wet Type

2021-6-29  The structure of the ball mill is simple. The discharge port is horn-shaped, and there is a screw device in it, which is convenient for discharging materials. The difference in working principle 1. Dry grinding Dry grinding means that when the ore is ground into the size we need, the powder will be brought out from the ball mill by the airflow.
