The effects of slurry pooling on ball milling have been investigated. •. Product fineness was found not to be a function of slurry pool volume. •. High ball filling J and slurry filling 1.0 ≤ U < 1.3 led to high production of fines. •. From a batch milling perspective, slurry pool is undesirable for effective grinding.
