The three groups of rolls are mounted on the framework and correspond to each other vertically, rough, intermediate and fine continuous crushing operation is carried out, qualified crushed products are produced, an intermediate screening and transfer link is omitted, the number of operators is decreased, energy resources are saved, the efficiency of a mill is improved, and the purpose of 'more crushing and less grinding' of a mine concentrating mill is realized.

Description

Combined oppositely rolling roller crusher
Technical field
The utility model relates to a kind of disintegrating machine, and particularly a kind of oppositely rolling roller crusher is mainly used in the crushing operation in middle-size and small-size metal mine ore dressing plant or stone pit.
Background technology
The all need in middle-size and small-size metal, non-metal mine or stone pit carry out grinding operation or require product to reach certain grade person, generally all will carry out multiple stage crushing, get into grinding process then.Current techniques is ripe and be " how broken few grinding process " by the technological process that everybody approved, promptly improves the ore fineness as much as possible in the muck stage, and then improves mill machine throughput, reduces power consume and ore grinding cost.
The current current technological process of production is to change two sections closed circuit mucks into the three-section closed circuit muck, and combo equipment commonly used is: jaw crusher-garden conic crusher-garden conic crusher-vibratory sieve connects with belt conveyer, chute, funnel between each equipment.Facts have proved that though spaller's process flow is after changing, the economic benefit of mine concentrator is significantly improved, this group crushing system complex structure, floor space is big, and manufacturing cost is high, and is difficult in maintenance.
Existing kibbler roll generally is used for middle-size and small-size mine, ore hardness in hard below, the branch of single roller, two roller is arranged, the branch of smooth roll, discaling roll is also arranged.Because of its maintenance load is bigger, the general use seldom.
The utility model content
The utility model technical problem to be solved is, a kind of combined oppositely rolling roller crusher is provided, and whole apparatus structure is compact, and floor space is little, and manufacturing cost is high, and is easy to maintenance, to overcome the defective of existing disintegrating machine.
It is following that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of combined oppositely rolling roller crusher comprises frame, and said frame bottom is connected with foundation bolt, and said frame upper end is connected with the pan feeding chute; Said frame lower end is connected with discharging chute; First drive roll and first driven roll of mutual gears engaged also are installed on the said frame; First motor also is installed on the said frame, and said first motor and first drive roll are in transmission connection; It is characterized in that: two groups of secondary drive rolls and two groups of secondary driven rolls also are installed on the frame under said first drive roll and first driven roll successively; Second motor also is installed on said frame, and said second motor is in transmission connection with twice level drive rolls respectively; Three drive rolls have identical specification, and three driven rolls have identical specification.
Be separately installed with one group of damping spring on the wheel shaft of each driven roll, an end of damping spring is connected on the frame.
The diameter of drive roll is greater than the diameter of driven roll.
Lining all is installed on said drive roll and the driven roll.
The good effect of the utility model is: three groups of running rollers are installed on the frame, and are corresponding up and down, carry out carse, medium and small continuous comminution process, produce qualified crushed product.Reduce middle screening transhipment link, reduced operating personnel, practiced thrift the energy, improved grinding efficiency, realized the target of mine ore dressing factory " how broken few mill ".
In addition, three groups of running rollers of the utility model all adopt double teeth roller, can increase broken production capacity greatly, improve the ratio of reduction.Adopt the discaling roll of same size, can effectively reduce accessory kind and quantity, increase interchangeability.Adopt motor, belt pulley to drive discaling roll and rotate, simple in structure, can and make series of products according to the user's request design.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of the utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, shown in 2, present embodiment comprises that the outside has the frame 7 of protective cover 2, and said frame 7 bottoms are connected with foundation bolt 6, and said frame 7 upper ends also are connected with pan feeding chute 1, and said frame 7 lower ends also are connected with discharging chute 5.On the said frame 7 also through bearing block be equipped with mutual gears engaged first drive roll 12 and with first driven roll 13, first motor 11 also is installed on the said frame 7, said first motor 11 and first drive roll 13 are in transmission connection.
Two groups of secondary drive rolls 10 and two groups of secondary driven rolls 9 also are installed on the frame under said first drive roll 12 and first driven roll 13 successively; Second motor 8 also is installed on said frame 7, and said second motor 8 is in transmission connection with twice level drive rolls 10 respectively; Three drive rolls have identical specification, and three driven rolls have identical specification.
Be separately installed with one group of damping spring 4 on the wheel shaft of each driven roll, an end of damping spring is connected on the frame 7.
Wherein, in order to increase rotary inertia, play balanced action, the diameter of above-mentioned drive roll is greater than the diameter of driven roll.
Lining 3 all is installed on said drive roll and the driven roll, and lining 3 is hemispherical or parabolic type profile of tooth.Through test lining 3 is hemispherical or parabolic type profile of tooth, than plain roller bigger frictional force and extruding Fracture Force is arranged, and the ratio of reduction increases to 10%~15% by 3%~4%, is applicable to medium-hard rock.When lining 3 wearing and tearing, available parallels adjustment spacing is changed in case of necessity.
During the work of this device, when rotating through belt transmission first drive roll 12, the first drive rolls 12, first motor 11 drives first driven roll, 13 backward rotation through meshed gears.Second motor 8 is same through twice level drive rolls rotations of belt drive, drives the secondary driven roll backward rotation in each area through meshed gears when twice the level drive roll rotates.
When this device carries out fragmentation; Ore particle gets between first drive roll 12 and first driven roll 13 from pan feeding chute 1, and the bulk ore particle is carried out fragmentation, following level during middling particle gets into; Two groups of secondary drive rolls and secondary driven roll ore particle carry out fragmentation, and qualified ore particle is derived from discharging chute 5.
For satisfying different production scales, different customer demands advise manufacturing and designing series of products.The parameter of series of products is listed in the table below.
