The rod mill is ideal for coarse grinding of brittle materials with low hardness or as the first stage of two-stage ball mill grinding. It ensures efficient grinding without excessive crushing. Recently, it has become popular in construction sand making.
The rod mill uses steel rods for dry or wet grinding. The particle size of the output material is fine and uniform, which can prevent over-grinding, but is coarser than the ball mill.
Get Latest PriceThe rod mill can grind these materials: rare metal ores (tungsten, tin), gold, iron, copper, quartzite, potassium feldspar, gravel, coal, glass, construction waste, cement clinker, fertilizer, etc.

A rod mill, driven by external gear, features a horizontal rotary cylinder. Material enters the first cabin with liner plates and steel rods. The rotating cylinder elevates and drops rods to grind the material. Coarse material moves to the second cabin for further grinding. Finally, powdery material exits from the discharge port, completing the process.
Rod mills offer a significant advantage with a large crushing ratio, resulting in a fine and uniform output particle size, albeit coarser than that achieved by a ball mill.
The steel rod grinding mechanism of rod mills ensures less over-crushing, breaking ore into coarse particles before further size reduction, leading to more efficient processing.
These rod mills deliver a high proportion of medium sand with good gradation continuity during the sand making process, meeting the production needs of various grinding mills and sand making plants, regardless of size.
These rod mills ensure efficient, low-maintenance operation, saving power and enhancing capacity.
