Grinding Balls is the key to improve the efficiency of the ball mill

Good quality Ceramic Ball Mill for sales
Good quality Ceramic Ball Mill for sales
Lipu provided me good after-sale service after buying their gold ore dressing plant, that’s important to me, will consider to buy the second plant.

I bought one complete 15tph sand drying plant from Lipu in 2012, it’s still running well, the dryer they supplied me is very durable.

Grinding Balls is the key to improve the efficiency of the ball mill

For a concentrator, the efficiency of the ball mill directly affects the economics of the concentrator. Therefore, it is very important for the concentrator to increase the work efficiency of the ball mill. The efficiency of the ball mill is constrained by a number of factors, among which the quality of the wear-resistant steel ball, which is the main grinding medium for the ball mill, plays a key role.
1. Current For the ball mill, increasing the current is to increase the rotational speed, the rotational speed is high, and the working efficiency of the ball mill is naturally higher. However, it should be noted that increasing the current should be within the rated power range of the ball mill. If the current is too large, the mill will be burned.
2, the choice of raw material formulation formula should be appropriate, this can not only improve the strength of the ball, but also increase its weight, thereby increasing its inertia, so that the work efficiency of the ball mill has been improved to some extent.
3. The speed increase of the deceleration device is the only way to improve the working efficiency of the ball mill. Therefore, appropriate improvements to the deceleration device can also have a certain effect. Conditional concentrators can also choose to install the inverter to adjust the speed. Satisfactory results.
4, water in the amount of water in the ore has a certain influence on the working efficiency of the ball mill. Therefore, an appropriate increase in the moisture content of the ore in the grinding chamber can also increase the efficiency of the ball mill.
5, dispersant added dispersant can also improve the working efficiency of the ball mill to a certain extent.
6, Steel ball The ball is the main grinding medium of the ball mill. The specific gravity of the ball is large, and its impact is also great. The abrasion resistance of the steel ball is good, and if the hardness is high, the grinding force is strong. For the hard-to-grinding ore with large hardness and compact structure, a steel ball with a large specific gravity and a large size should be added. However, in order to effectively grind fine-grained ore and increase the number of hits per unit time, more small-sized steel balls are required.
The proportion, hardness, composition and toughness of the steel ball are the main technical indicators of the steel ball. The quality of the steel ball is reduced, the grinding effect is significantly reduced, and the ball unit consumption is increased. Therefore, high-quality brand steel balls, which are produced by open-source anti-abrasion products, should be selected. They have high hardness, good toughness, good wear resistance, and are available in a variety of sizes to meet ball mill requirements for different materials. Ore individual needs, more appropriate.
