Key Factors in Choosing Rod Mill Over Ball Mill

Rod mills, also known as rod-mill sand-making machines, are a mineral processing machine for milling the materials into powders after they are crushed. Rod mills are mainly used for processing and crushing such ore and raw materials as feldspar, quartz and other materials. Rod mills can be operated at lower peripheral speeds than ball mills which make rod mills more energy-efficient. Rod mills also feature less void space, lower steel consumption and because of the higher weight of the steel rods are more suited to breaking down large mining ore. Rod mills are also easy to maintain since broken or worn rods are easy to remove and replace.

After the arrival of economic crisis,our mining machinery industry has been declined in China continued for nearly one year. And this drop caused incalculable damage to our economy.If our government start to construct high-speed railway, we will have high demands of grave. MB series rod mill has certain selective grinding effect in the grinding process because of the grinding medium and ore are line contacted. The product particle size is uniform, and excessive grinding ore grain is little .It is widely used in fine grinding and grinding operation of feldspar, quartz, abrasive, refractory material, cement, steel grit, slag , copper ore, iron ore, gold ore grit and other hard or brittle material.

Another key factor in choosing a rod mill over a ball mill is void space. You ideally want as little open space as possible so you have more grinding contact between the rods and the ore. Ball mills need more open space so the balls inside can cascade and grind but this space lessens the contact between metal and ore per surface area. Again, depending on the site project media rod mills won’t necessarily always be the better option but if you are concerned about void space in your grinding process a rod mill may be the right choice.
