Detailed Description
Product Description Shanghai Shunky rod mill adopts advanced feeding and discharging material control technology, and be equipped with suitable grinding body according to actual grinding materials. Shunky rod mill exchanges traditional surface contact into line contact, making discharge particle size more uniform, output higher and price more reasonable. Shunky rod mill is widely used in refractory, chemical industry, metallurgy, glass and other industries, which have high requirements on evenness of finished grinding products. It is also applied in building sand and other sand making industries over those years. Main use of rod mill: Preferred sand making machine for quartz sand in metallurgy and glass industry as well as for pebbles and other high hardness materials. Rod mill is generally used for coarse grinding. As to the rod mill, the curvature of its cone cap is small; its inner surface is equipped with smooth liners, while its cylinder liners are generally not smooth. Its hollow discharge shaft has larger diameter and enables the steel rod to move regularly in the rod mill and not skew, avoiding bending for mutual combating during falling. The rotation speed of rod mill is low, and the general rotation rate is 60%~70%. Its medium filling rate is also low, about 35% ~ 40%. Feeding size of rod mill is generally 25 ~ 30mm. Oversize ore blocks will bend or break the steel rod as well as leaves large space between rods, being hard to grind particles and causing output decrease. Ores are crushed and grinded by the“line contact” when the rod falls. The small particles are neglected by the rod until large particles are grinded. Therefore, over crushed phenomenon is rare, and product sizes are rather uniform in 1 ~ 3mm. So the rod mill is also called rod mill sand making machine. Features The rod mill is characterized by the line contact of grinding media and ores during grinding process, so the machine has a certain selectivity grinding effect. The rod mill makes relatively uniform particle size and less over crushed ore particles. When used for coarse grinding, the rod mill has larger handling capacity against the ball mill in equal specifications, and vice versa. Compared with the old equipment, the rod mill has the following advantages: 1: Save power. Compared with the old ones, it saves power more than 40%. 2: Shanghai Shunky rod mill adopts advanced feeding and discharging material control technology, and be equipped with suitable grinding body according to actual grinding materials. It exchanges traditional surface contact into line contact, making discharge particle size more uniform and output higher. Shunky rod mill is suitable for grinding ores with Mohs hardness of 5.5 to 12. 3: Discharge fineness is adjustable. Only small adjustment is ok to change the discharge size. The inner is fixed fineness control device, and screening device is available to control discharge. The two checks ensure no over grinding and stop unqualified products mixing in finished products. 4: Rod mill has dry type and wet type. You can choose from them according to your actual situation. For processing quartz sand, dolomite, monazite and other products, the rod mill can be equipped with a magnetic separator to remove iron.
