Common crushing processes of ore dressing plant are there?
Common crushing processes of ore dressing plant includes two section crushing circuit and three section crushing circuit. two section crushing circuit is divided into two open and two closed-circuit.
The latter's second crushing machine and check the screening into a closed circuit, we can guarantee that the product size to meet the requirements will not affect the next grinding operation, Sec process is only suitable for small-scale mining of the underground mining method, the total crushing tbm non-large, generally about 15 to 25, the crushing stone is not many, and often less tbm 1000 tons / day.
Two open process is rarely used, but in certain re-election plant open with two processes, the crushing products of the proceeds to send the rod mill or jig, most of the ore dressing plant using the two sections of a closed circuit.
The three section crushing circuit there are three sections open and three sections of a closed-circuit points. Have a pre-screening before a three-segment crushing, but without pre-screening in the first paragraph or second paragraph. The three sections open mainly because we can not guarantee that the grain requirements of the final product, it seldom use. The three sections of a closed-circuit screening process in the third paragraph to check into a closed circuit. This is the most common processes. In large, medium and small ore dressing plant, its total crushing ratio is larger, up to about 25 to 200, the maximum feed size of up to about 1000 mm, crushing, product size can reach 12 mm or smaller more.
