Rod Mill Introduction：
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.
Working principles：
Depending on the reduction box and the reduction of the peripheral big gear wheel, the motor rotary drives the cylinder rotating or the motor drives the cylinder rotating directly by the peripheral big gear wheel. And inside the cylinder, there?ˆ™s an appropriately grinding medium-steel bar .The steel bar will drop after reaching a certain height with friction and the centrifugal force. And the material will be hit and grinded to achieve the purpose of making sand.
Features and Benefits：
1. Higher capability and more even discharging size. Adopted advanced technology of sand maker-rod mill by controlling the input or output materials; related to the user?ˆ™s actual grinding materials, choosing an appropriate grinding medium, replaced the traditional surface contact to the linear contact . Therefore, its discharging size is more even, the capability is higher, suitable for various hardness of ore.( Moths hardness 5.5-12)
2. Adjustable fineness of limestone. Through simple adjustment, will change the discharging size, and inside, has finesse control device and screening device, ensuring not over grinding and avoiding the unqualified product interfusing into end products.
