Ball mill and rod mill which is better?

Ball mill and rod mill are important two kinds of equipment for material grinding, powerful, wide range of applications, can be a variety of materials for grinding, then when choice the grinding equipment, many users are confused in ball mill and rod mill which one is better? The following analysis to answer everyone's doubts. 1. Differences between ball mill and rod mill. (1) Grinding media Ball mill grinding media is a ball-shaped material, rod mill grinding media is made of rod-shaped material. (2) Shape ratio Ball mill cylinder length and diameter values vary greatly, the ratio of many types of models is not much difference, generally not more than 1, but the rod mill cylinder length and diameter ratio is generally 1.5-2.0, both the appearance of some difference. (3) Ability to handle materials The grinding fineness of two mills is different, rod mill grinding media have linear contact between the material, big grinding area, product size uniformity, during the rough grinding of the material, the output of the rod mill is higher. But the same specifications of the ball mill grinding fineness of the finished product is lower than the rod mill, more suitable for more fine grinding of the material. 2. Advantages of ball mill and rod mill (1) Ball mill a. Ball mill drive and grinding energy consumption reasonable match, can greatly reduce the system's energy consumption. b. A reasonable configuration of the discharge port and the feed port not only increases the intensity of the feed, but also increases the discharge amount, doubling the production capacity of the entire system. c. The main bearing uses a double row of self-aligning stick support, reducing the friction between the bearings, reducing energy consumption, the system greatly reduce the start-up time, easy to start. (2) Rod mill a. Rod mill product of uniform texture, excellent grain shape, high yield of finished products, compared to the old equipment, saving more than 40% energy consumption. b. Adopt advanced control technology of material in and out, improve the traditional surface contact grinding to line contact grinding, and increase the output of the milled material by 50%. 3. How to choose ball mill and rod mill? (1) According to the desired product size to choose. When used for fine grinding, the particle size of the product is less than 0.5mm, the ball mill grinding effect is greater than the rod mill. When used for rough grinding, the particle size of the product is 1-3 mm, the processing capacity of the rod mill is higher than the ball mill. Rod mill to the mine size is generally 15-23mm. (2) Grinding material types Rod mill can be applied to different hardness (Mohs hardness 5.5-12) ore, materials, ball mill range is smaller. Ball mill and rod mill scope, grinding methods vary, for different materials grinding, the user can choose according to their actual production requirements.
