Several problems caused by rotary kiln in beneficiation production line work

Several problems caused by rotary kiln in beneficiation production line work

Rotary kiln is also a kind of beneficiation equipment often used in most beneficiation production lines. In the process of beneficiation, the rotary kiln is used to magnetize lean iron ore, so that the original weak magnetism of the ore is changed into strong magnetism, so as to facilitate magnetic separation. According to the use of rotary kiln, several problems caused by rotary kiln in mineral processing production line were summarized.

Tailings enrichment facility

Tailings enrichment facility

The concentration of tailings pulp discharged from ferrous metal and non-ferrous metal gravity processing is generally low. In order to save the consumption of fresh water, reduce the investment and operating costs of water supply and tailings transport facilities of the beneficiation plant, enrichment ponds are often built in front of the plant to recover tailings water for recycling in beneficiation production.

Rules for installation and operation of ball mill series beneficiation equipment

Rules for installation and operation of ball mill series beneficiation equipment

Whether the ball mill working process is high efficiency and low fault, not only depends on the quality of the ball mill, in many cases, also depends on the installation environment and installation quality of the ball mill. The operation of all types of ball mills is not different in the installation process. In order to ensure that the ball mill can work smoothly and no bad conditions occur in the process of machine operation, attention should be paid to the construction of its installation base. Generally, we need to install the ball mill on a reinforced concrete base 2.5 to 3 times its weight or more. The base should also be built in a safe, stable and sturdy place. Keep a certain distance from the plant.
