Mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. according to the feeding and nesting size size crushing operations are often divided into coarse crushing ,medium crushing and crushing. The commonly used equipments are compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, and so on.
Magnetic separation plant magnetic iron recovery Factors Influencing analysis to investigate the magnetic separator wide means of magnetic iron recovery, organization, and take measures, according to the findings of received good results.Introduced in order to facilitate the analysis and discussion of the problem as follows: (1) produce crystals of magnetic iron distribution rate of the grain production of magnetic iron crystal what the crystal how the ratio of total iron. (2) grain production the magnetic iron distribution rate for the plot of the rate of distribution of magnetic iron and iron recovery in grain production. (3) the magnetic iron crystal He calculated magnetic tube-like crystal - 200 mesh accounted for 100% of field strength 158kA / m under the conditions magnetic analysis.
The crushing processes for the three sections of open circuit crushing and crushing pre-screening process, the feed size is 1000 to 0 mm, the final crushing particle size is 95% - 25 mm. Broken system maximum hourly throughput is more than 3,000 tons, if the use of closed-circuit operating cycle load will reach sword 80 to 100%, and the need to be equipped with two wider than 1600 mm tape transport system, high investment. In order to ensure that the final crusher product size requirements - 25 mm thick broken using PX1200/180 gyratory crusher 2 units, one at each design station to a capacity is 1480 tons, the actual production capacity is 1124 to 1606 tons. The magnetic separator adopts the operation a rougher time selection and a sweeping election. Roughing and selected semi-counterflow binoculars permanent magnetic separator (CYT750 × 1800 mm), with particle sizes is 0.4 to 0 mm, table and a capacity is 36 tons, the production of Chinese Communist Party adopted 96 units, including crude elected 46 units, scavenging a capacity is 31 tons, 32 production. Production time and hard ore mill the best years of operating is only up to 80%.
