Introduction

It plays a huge role in the development of national economy.In some special conditions, often need special material steel ball, to complete the different environment required to achieve the function.In fact, some special material steel ball has been widely used in various fields of the national economy, including high chromium steel ball;High chromium steel forging;Low chromium steel ball;Low chromium steel forging;Chrome series liner board;Manganese series liner plate;Hammer head;Multivariate alloy steel ball;Multi-alloy lining plate;All kinds of wear-resistant materials;.Their popularization and application not only promoted the development of ball mill steel ball production industry, but also promoted the technical development and scientific and technological progress of related industries.

As in general grinding media ball manufactured from steel and cast iron. It has various applications in that grinding purpose is what stands at first. Be the miling particles are moisture or dry it will grind. Mostly these balls are used in the manufacturing process. There are various types of balls. Each of the balls has specific features it means a lot for the special production process.

Ball mill steel ball is the ball mill equipment to grind the material medium, through the ball mill between the ball ball and the friction between the ball ball and the material to produce the grinding effect, important basic parts, especially the precision industrial steel ball plays a huge role in the development of national economy.Widely used in cement plants, power plants, etc.High and low chromium multi-element alloy steel ball, high and low chromium multi-element alloy casting and forging.

usage

Ball mill is the key equipment to crush the material after it is broken.

Ball mill is one of the high fine grinding machines widely used in industrial production.

There are many kinds, such as horizontal ball mill, ball mill bearing bush, energy saving ball mill, overflow type ball mill, ceramic ball mill, grid ball mill, etc.

Ball mill is suitable for grinding all kinds of ore and other materials, is widely used in mineral processing, building materials and chemical industries, can be divided into dry and wet grinding methods.It can be divided into two types, grid type and overflow type, according to different discharging modes.

Folding requirements

The output of the ball mill is not only affected by the loading capacity of the ball, but also related to the diameter of the ball.Requires a certain ball diameter and different ball diameter of the ball to maintain a certain proportion of the relationship, the general cylinder body ball diameter size range is 25--60mm.If the barrel body is a large diameter of the ball, the impact force is larger, is favorable for crushing large lumber coal, but due to the large gap between the ball and the ball, the relative surface area is small, the extrusion, grinding effect is weakened, on the coal mill output and coal fineness are adverse.There are too many small diameter steel balls in the barrel body and the impact force is small, which will decrease the output of the coal mill. At the same time, due to the relative increase of the surface area of the steel ball, the wear of the steel ball will increase, and the power consumption of coal grinding will rise accordingly.

For example, during the operation of the coal mill, the weight and diameter of the steel ball are constantly decreasing due to wear and tear, so it is necessary to regularly fill in a new ball to maintain a certain load of the steel ball.Generally, large diameter balls are added, and the amount of balls should be determined according to the wear rate of steel balls (the wear amount of steel balls per ton of coal grinding) and the amount of coal grinding.After running for a certain time, the number of small diameter steel balls in the barrel increases.Therefore, after running for about 3000 hours, it is necessary to stop and clean the steel ball, so as to remove the ball with the diameter of less than 15mm and the broken ball, and fill the new ball at the same time.

Folding method

The newly installed ball mill has a running-in process. In the running-in process, the steel ball volume is added for the first time, accounting for 80% of the maximum ball volume of the ball mill. The ratio of the steel ball can be added according to the size of the steel ball (Φ120㎜, 100㎜, 80㎜, 60㎜, 40㎜).Different ball mill models have different ball loading capacity.For example, the maximum ball loading capacity of MQG1500×3000 ball mill is 9.5-10 tons.The first addition of steel ball ball (120㎜ and 100㎜) accounted for 30%-40%, in the ball 80㎜ accounted for 40%-30%, small ball (60 and 40㎜) accounted for 30%.

Why ball mill ball in the process of ball mill in quantity only to add 80%, because after installation of ball mill, ball mill need mesh size, capacity are to be gradually increased, with ball mill is normal running in two or three days in a row, pick up to check the size of the gear meshing situation, everything is all right, open the add the remaining 20% steel ball mill manhole covers the second.

Note:

the addition of small steel ball is only the first time to add ball.Because, when the ball mill is running normally, the reasonable friction between the steel ball and the steel ball, the steel ball and the ore, the steel ball and the lining plate of the ball mill will increase the wear, so that the large ball mill is small and the middle ball mill is small ball.So normally under normal circumstances, you don't need to add a ball.The case of adding pellets is that when there is no monomer dissociation in the particle size of useful minerals, an appropriate amount of pellets can be added when the fineness of grinding machine fails to meet the requirements of flotation.In order to keep the filling ratio of ball load and the reasonable ratio of ball, and to keep the stable operation of ball mill, the ball must be compensated reasonably and the ball must be worn with low compensation.

The weight added by the steel ball is determined by the quality of the steel ball and the quality of the steel ball. It is best to use the new wear-resistant steel ball, such as the steel ball forged by the special treatment of the train wheel hub, which is particularly wear-resistant.
