For a long time, the sand making market has been booming! Mineral processing equipment sand making machine ball mill and rod mill is also one of them, not only high efficiency, large output, but also the finished product uniform and delicate, high quality, so for sand production ball mill and rod mill which sand making is better? The following Jiangxi Hengchang mining machinery manufacturers take you to understand:
  
From the aspect of crusher, whether it is a ball mill or a rod mill, when the cylinder rotates, the grinding medium (ball or rod) installed in the cylinder is lifted to a certain height with the rotation of the cylinder under the action of friction and centrifugal force, and then thrown down at a certain linear speed, so that the coal block in the cylinder is impacted, grinding and extruded, and the coal block is crushed. And then the difference is:
  
(1) The ball mill needs steel balls to fall at a higher place at a higher speed, the impact energy is large, and the crushing effect will be good, but the power consumption is also large. The rod mill mainly relies on grinding and extrusion between rods and rods, the speed is low, and the relative power consumption required is also low.
  
(2) The working characteristics of the rod mill are that the coal block is screened during the movement between the rod and the rod, which can make the large granular coal be lifted to the highest position of each layer and concentrated in a place with strong crushing capacity for crushing. Therefore, the rod mill for coal crushing operation has high efficiency, low power consumption, uniform particle size of coal, and less slurrying.
  
Ball mill
  
1. What are the respective advantages of ball mill and rod mill in sand making operations?
  
1. The quality and fineness of ball mill and rod mill are different:
  
The particle size of the finished product of the ball mill is generally between 0.074-0.4 mm, the finished particle size of the rod mill is generally between 0.833-0.147 mm, the finished product of the ball mill is relatively fine, and the finished product of the rod mill is relatively rough, but relatively uniform. Therefore, it is recommended that users who have high requirements for the fineness of the finished product use a ball mill.
  
2. The operating efficiency and output of ball mill and rod mill are different:
  
Rod mill adopts the most advanced controllable feeding and discharging technology, according to the processing material selection of the use of suitable grinding body, a change of the traditional ball mill point contact to line contact, so that the finished particle size is more uniform, the output is also higher, so the finished product fineness requirements are not so high enterprises, in order to save costs, increase economic benefits, you can choose rod mill.
  
In summary, the fineness of the ball mill material is high, the discharge particle size is fine, and it is easy to grind finely, but its over-crushing phenomenon is serious, the finished sand produced by the rod grinding machine is rougher, but the particle size is uniform, containing less coarse particles and sludge, and the over-crushing is lighter, most of them say that users choose more sand from the rod grinding machine.
