Technical field
Ore-sorting system equipment is the utility model is related to, specifically, is related to a kind of novel mineral crushing system.
Background technology
It is broken and grind that the energy consumption of operation, steel consumption ratio shared in being produced in ore dressing plant are very large, and some factories are even
Reach 60%-70%, so the change of crushing circuit, directly affect the economic benefit of Mineral Processing Enterprises.Product granularity is reduced, is carried
High ball mill disposal ability, is improved into mill grade, is reduced into mill amount, it is that comminution engineering power-saving technology is entered that reduction, which grinds operation consumption,
The mark of exhibition.
By technique and production scale, crushing process flow is roughly divided into one section of coarse crushing flow, two sections of crushing circuits and three sections
Crushing circuit.Current most of ore dressing plants all use Three stage crushing with single closed circuit stage flow.As shown in figure 1, coarse smash equipment 2 uses jaw
Disintegrating machine, it is broken in entering below crushing raw ore to 200~300 millimeters of particle diameter；The broken standard cones of equipment 3 crush in passing through again
Crusher machine enters back into fine-crushing department to less than 70~75 millimeters；Now after the short head cone crusher of fine crushing device 4 is in small, broken bits, grain
Degree just reaches 12 millimeters；After the screening of the first screening plant 5, the particle higher than 12 millimeters returns to operation in small, broken bits, less than 12
The ball-grinding machine 6 that is directly entered below millimeter carries out grinding process.Disappeared it can be seen that the material into grinding process is larger, during ore grinding
The amount of abrasive of consumption increases, and the desired time is also grown.Due to being limited by appointed condition, crushing operation uses such mode for a long time,
Cost consumption is huge.
