Rod Mill / Rod Grinder / Rod Grinding Machine For Sand Making

At present, rod mill is the most effective crushing machine and its performance has achieved the international standard. It is widely applied in the gravel industry. And it is mainly used for processing or crushing the feldspar, quartz, minerals and other raw materials, and it is also suitable for finely or secondarily crushing the various tough or brittle materials, such as grinding material, refractory material, cement, steel shot, pulverized slag, copper ore, iron ore, gold ore, concrete aggregate, bituminized aggregate. Now it is a most advanced high-efficient low consumption sand-maker in the world.

As with other types of mills, a rod mill is used to grind material into fine powder, but differs from a ball mill in that it employs long steel rods instead of balls as the grinding medium. The mill length is limited by manufacturing constraints for the grinding rods. Rod mills are typically used for grinding ores, coal/coke, and other materials for both wet and dry applications. Length-to-diameter ratios should be kept above 1.4 to prevent rod entanglement. In general, rod mills create a coarser product than do ball mills. Rod mill speed is typically slower than a ball mill.
