Description

(1) Technical field

[0001] The invention relates to an ore crushing and grinding system and a control method thereof. (2) Background technology

[0002] After the ore mined from the mine is sent to the concentrator, it must go through the crushing and grinding system for crushing, screening, grinding and grading to reach a suitable particle size before it can be flotation. The existing crushing and grinding system includes crushing, screening, grinding, and grading. Crushing and screening are all dry operations, and there are many reciprocating material conveying belts. Numerous dust generation points generate a large amount of dust, which is harmful to operators and The surrounding environment is greatly affected, and ventilation is required to collect dust. When encountering materials with high mud content or high water content, it is very easy to cause the crushing cavity and screen hole of the crusher to be blocked, affecting the operation.
