where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
To estimate the circulating load in and the efficiency of a classifier operating in closed circuit with a ball mill. Original feed may be applied at the ball mill or the classifier. T—Tons of original feed. X—Circulation factor. A—% of minus designated size in feed. B—% of minus designated size in overflow.
Finally, the material smaller than 20mm is transported to the hopper with an electromagnetic vibrating feeder and evenly fed into the ball mill. 2. Grinding system: Ball mills grind fine ore rocks into a fine powder to release the gold in the rocks. Then, the output material enters the spiral classifier for classification. Return the large ...

As a result, mineral processing is designed to yield the maximum amount of mineral concentrate possible before products hit the market. ... The ball mill product ...
With ballmill grinding being one of the most energyconsuming techniques, setting the optimal values of the operational and mineralogical parameters for efficient grinding is a key target in mineral processing plants [6,7,8,9,10]. Ball size is one of the key factors of ballmill efficiency [11,12], and may have a significant financial impact .
Working Principle Our ball mills work by putting chrome steel balls or ceramic balls into a rotating hollow cylindrical shell that rotates around its axis as friction grinds materials in an extremely fine form. As attrition size reduction is involved, the nanostructure size of the slurry of material is affected by the number and size of the balls.
