Ball mill cooling method that can dedust the crushing workplace

Abstract

The invention relates to a ball mill cooling method capable of dedusting a crushing workplace. According to the method, a ball mill comprises an induced draft fan, wherein an air outlet of the induced draft fan is communicated with an inner cavity of a cylinder body of the ball mill through an air pipe; a plurality of air inlet pipelines are communicated with the air inlet of the induced draft fan; an air inlet of each air inlet pipeline is formed in the crushing workplace; and when the cylinder body of the ball mill needs to be cooled, the induced draft fan performing air suction on the crushing workplace and forcible air cooling on the inner wall of the cylinder body, and the dust is adsorbed in slurry in the cylinder body of the ball mill. Through the adoption of the method, the cooling time of the ball mill can be shortened; the grinding efficiency of the ball mill is improved; the crushing workplace can be dedusted; and the production is improved.

Description

technical field [0001] The invention relates to a method for cooling a ball mill, in particular to a method for cooling a ball mill that can remove dust from a crushing workplace. Background technique [0002] The dust in the ore crushing operation site is serious. In a certain area, the staff can only enter the workplace with air respirators. After a period of precipitation, a thick layer of mineral powder will be piled up on the surrounding ground, which will bring great harm to the production. Big inconvenience, need to arrange staff to clean up regularly. [0003] The space of the crushing operation site is relatively limited, a large amount of dust is deposited in the area, and it takes a long time for manual cleaning, which affects the continuity of the production system. Secondly, this dust removal method requires personnel to enter the site, which brings harm to personal health. In addition, the cleaned ore powder will also bring environmental pollution to surroundi...

[0003] The space of the crushing operation site is relatively limited, a large amount of dust is deposited in the area, and it takes a long time for manual cleaning, which affects the continuity of the production system

Secondly, this dust removal method requires personnel to enter the site, which will bring harm to personal health. In addition, the cleaned ore powder will also bring environmental pollution to surrounding sites during transportation.

[0004] In the grinding operation site, when the temperature in the barrel of the ball mill reaches 70-80°C during operation, the grinding effect decreases, so that the grinding operation in the barrel of the ball mill is difficult to complete, and the temperature must be lowered to about 40°C, while the ball mill is naturally cooled. It takes a lot of time, about 4 hours, which greatly affects the maintenance progress
