Typical Ball Mill Charge Levels

How much steel goes into a ball mill

Here is a table that approximates how much steel charge, or how many tonnes to steel balls are needed to obtain a given type of grind in a specific size mill. The table assumes you are running the mill at 50% charge.

BTU Energy Required to Dry Ores and Concentrates

BTU_Energy_Required_to_Dry_Ores_and_Concentrates

To Drive off Moisture (theoretical) per Ton (2,000 lbs.) of Dry Material. Total B.T.U. include 63,840 B.T.U. to raise temperature of material from 60° F. to 212° F. at which point evaporation takes place (at sea level); specific beat of material taken as 0.21. Coal assumed to have 12,000 B.T.U. per’lb. as used and is […]

Calculate the Capacity of an Agitator & Conditioner

Conditioner Capacity Table-Chart

Example 1) It is desired to give 48 hours of contact on 100 tons per 24 hours of 2.7 specific gravity ore in a pulp of 40% solids (1:1.5). What size agitators will be needed? Total volume equals 59.85 –> from our Pulp Density tables. Tons feed equal 100. 59.85 time 100 equals 5,985 cu. ft. (total […]
