Technical Data

Ultra ball grinder also named ultra-fine powder ball mill, it is a commonly used ball mill in ore dressing production.

The ultra-fine powder ball mill is suitable for grinding various ores and other materials. It is a beneficiation equipment with high grinding precision.

Utra ball grinders can be divided into dry and wet grinding methods.

After the material is processed by the ultra-fine powder ball mill, it has the characteristics of fine discharge, large production capacity and high availability.

Work process of ultra ball grinder

After the material is roughly broken, it enters the ultra-fine ball mill by the lifting and conveying equipment.

The grinding medium in the mill relies on the energy obtained when the mill rotates to impact and grind the material.

The pulverized material enters the self-split micro powder classifier through the unloading bin for classification to realize the separation of coarse and fine powder.

The qualified fine powder is collected by the collector, and the coarse particles are re-entered into the ball mill from the lower end of the classifier to be crushed.

The purified gas is discharged by the induced draft fan.

Mechanical structure of ultra ball grinder

The ultra-fine powder ball mill is composed of the main parts such as the feeding part, the discharging part, the rotating part, and the transmission part (reducer, small transmission gear, motor, electric control).

The hollow shaft is made of cast steel, and the inner lining is removable. The large rotary gear is processed by casting gear hobbing. The cylinder body is inlaid with a wear-resistant liner, which has good wear resistance.

The main body of the ultra-fine powder ball mill includes a cylinder in which a liner made of wear-resistant material is inserted in the cylinder, and there are bearings that carry the cylinder and maintain its rotation. There are also driving parts, such as electric motors, and transmission gears, pulleys, and V-belts.

Blades are generally not the main components. There is an internal spiral in the component feed port at the feed end, which can be called an internal spiral blade, and an internal spiral in the component discharge port at the discharge end, can also be called an internal spiral blade.

Working principle of ultra ball grinder

The work of ultrafine ball mill is driven by the motor to drive the main shaft and turbine to rotate at a high speed (the speed can reach up to 700r/min).

The grinding block on the turbine and the screen ring forms a crushing and grinding cavity.

The material enters the machine cavity from the hopper, rubs tightly and strongly impacts the inner edge of the turbine blade under the action of the rotating airflow, and grinds again in the gap between the blade and the grinding block.

While crushing and grinding materials, the turbine sucks in a large amount of air, which plays a role in cooling the machine, grinding materials and conveying fine materials.

The fineness of material crushing depends on the nature of the material and the size of the screen, as well as the throughput of the material and air.

Extended question: How to load balls into the ball mill?

In order to effectively crush the material, several principles must be followed when determining the gradation:

First of all, the steel ball must have enough impact force so that the steel ball of the ball mill has enough energy to crush the particulate material, which is directly related to the maximum ball diameter of the steel ball.

Secondly, the steel ball must have enough impact times on the material, which is related to the filling rate of the steel ball and the average ball diameter. When the filling amount is constant, under the premise of ensuring sufficient impact force, reduce the diameter of the grinding body as much as possible, increase the number of steel balls to increase the number of impacts on the material, and improve the crushing efficiency.

Finally, the material has enough residence time in the mill to ensure that the material is fully crushed, which requires the steel ball to be equipped with a certain ability to control the flow rate of the material.

The so-called two-stage ball grading method is to use two different sizes of steel balls with a large difference in diameter for grading.

The theoretical basis is that the gaps between the large balls are filled by small balls to fully increase the packing density of the steel balls.

In this way, on the one hand, the impact capacity and the number of impacts of the mill can be improved, which is in line with the functional characteristics of the grinding body. On the other hand, the higher bulk density enables the material to obtain a certain grinding effect.

In the two-stage ball distribution, the main function of the big ball is to impact and crush the material. The first function of the small ball is to fill the gap between the big balls and increase the bulk density of the grinding body to control the flow rate of the material and increase the grinding capacity;

It plays the role of energy transfer and transfers the impact energy of the big ball to the material; the third is to squeeze out the coarse particle material in the gap and place it in the impact area of the big ball.
