How to increase the stainless steel hollow ball according to the size of the steel ball?
This depends on the diameter of the ball mill, the hardness of the ore, the particle size of the ore entering the ball mill, and the hardness of the steel ball (Quality), Ball mill speed and other factors to determine. When the type of ball mill is determined, the speed of the ball mill is fixed. The hardness of the ore is measurable. The particle size of the ore entering the ball mill is determined by changing the sieve size. Usually, the newly installed ball mill has a stainless steel ball bonding process for grinding bottles. In the running-in process, the amount of steel balls increases at one time, accounting for 80% of the amount of stainless steel balls used for large hinges of the ball mill, the increased share of the steel ball can be based on the steel ball scale ( φ 120 ㎜, φ 100 ㎜, φ 80 ㎜, φ 60 ㎜, φ 40 ㎜)The size is increased.
stainless steel hollow ball factory, steel ball increase: Different ball mill types have different total ball loading. For example, MQG1500 × 3000 ball mill (Processing Capacity 100-150 tons)Large ball loading 9. 5-10 tons. Increase the steel ball at a time (120 ㎜ and 100 ㎜)Accounting for 30%-40%, the ball 80 ㎜ accounted for 40%-30%, small ball (60 and 40 ㎜)Accounting for 30%. Why is the amount of steel balls only increased by 80% in the running-in process of the ball mill? After the ball mill is installed, the giant and fine teeth of the ball mill need to be meshed, and the processing capacity (Ore volume) It is also necessary to gradually increase. After the ball mill is running normally for two or three days, stop the ball mill to check the meshing status of the giant and fine gears. When everything is normal, open the manhole cover of the ball mill 2nd times and increase the remaining 20% steel balls.
after the ball mill starts up normally, the increase of steel balls in each shift is 3: 4: 3 ( 120 ㎜ is 3, 100 ㎜ is 4, ㎜ is 3)Increase. Note: the increase of small steel balls is only used for the ball. Due to the reasonable grinding between the steel ball and the steel ball, the steel ball and the ore, the steel ball and the ball mill liner during the normal operation of the ball mill, the wear will increase, and the large ball milling will be small (Grinding into a ball)The middle ball is a small ball. Therefore, under normal conditions, there is no need to add a small ball. The condition of adding small balls is that there is no monomer dissociation in the particle size of useful mineral deposits, and appropriate small balls can be added when the fineness of grinding machine does not meet the flotation request. The steel balls in the ball mill are constantly worn during the operation process. In order to maintain the reasonable ratio of the ball charge filling rate and the ball, and to maintain the stable operation of the ball mill, it is necessary to carry out reasonable ball filling and low wear.
The increased weight of stainless steel hollow spheres is based on the quality of steel balls and the quality of steel balls, which determines the increase in ore consumption per ton. New wear-resistant steel balls are used. Better (Good quality) The increase in steel balls is calculated according to the amount of ore processed per ton (That is, an increase of 0. 5% per ton of ore. 8 ㎏)The usual steel ball needs to process one ton of ore (1 ㎏-1. 2 ㎏). Steel Ball Size Share: Different ball mill types have different proportions. The diameter of the ball mill is below 2500 ㎜, and the steel ball size is increased to 100 ㎜, 80 ㎜ and 60 ㎜. The diameter of the ball mill is above 2500 ㎜, and the steel ball size is increased to 120 ㎜, 100 ㎜ and 80 ㎜.
