Description
Technical field
The present invention relates to ore grinding technical field, and in particular to a kind of wet type roll-type grinding system.
Background technology
Need to be sorted after ore first is ground into valuable mineral and gangue mineral monomer dissociation in mine ore dressing flow,
Therefore, grinding attachment is widely applied in mine.At present, each mine of China uses wet type horizontal drum formula ball mill mostly
Ore grinding is carried out, energy consumption of the ball mill in grinding operation is accounted for entirely selects the 50%~70% of factory's energy consumption, is the big consumption for selecting factory owner to want
Can operation.Ball mill ore grinding principle is, using the rotation of grinding machine roller, to drive the steel ball in cylinder（Steel section）Medium enters to mineral
Row is broken and is ground.The grinding machine roller of ball mill and the weight of abrasive media and 5~10 times of weight of material about in ball mill,
Medium is low to the probability of material impact, there is substantial amounts of steel ball in operation process and pounds steel ball, liner plate phenomenon, and idle work consumption is big,
And because grinding mill barrel rotating speed is low, material number of times is few, effect is low for abrasive media impact, causing material, levigate time-consuming.Therefore,
Tumbling ball mill generally existing that energy utilization rate is low, the low shortcoming of grinding efficiency.Additionally, also being existed using ball mill ore grinding
That occupation area of equipment is big, capital expenditure big, high energy consumption, noise are big, ball medium and the problems such as big liner plate metal consumption.
Under the conditions of same treatment amount, for ball mill, roller type vertical mill machine has weight of equipment to roller type vertical mill machine
Advantage small, that substantial amounts of metal material can be saved.Roller type vertical mill machine is different from ball mill ore grinding principle, and roller type vertical mill machine is using mill
Roller rolled to bulk materials, fine granules are carried out with high-pressure extrusion and the pulverization principle of shearing carries out grinding, therefore its idle work
Few, by accelerating speed of grinding plate, material can be more by roller, therefore, the mill efficiency of roller type vertical mill machine is high, capacity usage ratio
It is high.But current roller type vertical mill machine may be only available for dry type mill, the material higher to moisture needs high-temperature hot-air to realize during grinding
Side edging is dried, and to use high-power blower, and roller type vertical mill dry grinding to need powder concentrator to control fineness in system, and product is received
Collected using cyclone cylinder with respect to coarse grain during collection, collected using pulse bag-type dust-removing with respect to particulate, therefore, select powder energy consumption also suitable
Greatly.
