Bucket elevator；7, material diffusion facilities；8, fine screen equipment；9, wet equipment is mixed.
Specific embodiment
As shown in Figure 1, a kind of aggregate processing method, comprises the steps of: big aggregate is sent by step 1 pre-shaped
Pre-shaped equipment 3 obtains small aggregate；Step 2 primary dcreening operation, by Jing Guo pre-shaped aggregate be sent into just sieve apparatus 4, by aggregate into
Row classification；Step 3 finishing shape, by smart shaping device 5, will make aggregate reach requirement by the aggregate of first sieve classification；Step 4
The aggregate of step 2 primary dcreening operation and/or the aggregate of step 3 finishing shape are sent into fine screen equipment 8, according to partial size to aggregate by fine screen point
Fine screen point is carried out, the processing of aggregate is completed.
By the processing of four steps, not only large-sized aggregate can be processed into small particle aggregate, it can also be by bone
Material not only increases the overall utilization rate of aggregate according to grain size grading to meet the needs of different application scene, moreover it is possible to reduction pair
The influence of ready-mixed concrete pumping, improves the construction workability of concrete, reduces concrete quality hidden danger.
When due to pre-shaped, if feed is uneven, it will cause the idle running of part-time pre-shaped equipment 3, but in addition
The situation of partial time period overload operation.In order to be fed as far as possible uniformly, a vibration is set before pre-shaped equipment 3 and is given
Expect equipment 1, be fed by vibratory feeding equipment 1 to the pre-shaped equipment 3 of step 1, to reach the uniform purpose of feed.
Since pre-shaped equipment 3 itself will be crushed the aggregate of greater particle size, pre-shaped equipment 3 is easier to damage.
Such as encounter the original aggregate that iron-content is high, hardness is big, then it is bigger to the damage of pre-shaped equipment 3.For this purpose, in vibratory feeding equipment
Electromagnetism equipment for removing ferric ion 2 is additionally provided between 1 and pre-shaped equipment 3, aggregate is sent into described pre- whole after electromagnetism equipment for removing ferric ion 2 is except iron
Shape equipment 3.
It can be removed in aggregate by electromagnetism equipment for removing ferric ion 2 and contain ferrous components, to favorably protect pre-shaped equipment 3, mentioned
Its high service life.
In step 2 primary dcreening operation, aggregate is divided into A, B, C, D level Four, A grades of aggregates by partial size from big to small by first sieve apparatus 4
The shaping again of pre-shaped equipment 3 described in return step one, B grades of aggregates enter step three described in smart shaping device 5 carry out essence
Shaping, pre-shaped equipment 3 described in C grades of aggregates return step one as needed or enters step the three finishing shape and sets
Standby 5 or it is directly entered the fine screen equipment 8 of step 4, the fine screen equipment 8 that D grade aggregates are directly entered step 4 carries out fine screen and divides.
In the fine screen point of step 4, aggregate is divided into A, B, C, D level Four by partial size from big to small by fine screen equipment 8.
Under normal circumstances, the aggregate come either is screened out through first sieve apparatus 4 or fine screen equipment 8, the partial size of A grades of aggregates is greater than
The partial size of 32mm, B grades of aggregates is greater than 10mm and is not more than 32mm, and the partial size of C grades of aggregates is greater than 4mm and is not more than 10mm, D grades of bones
The partial size of material is not more than 4mm.
By classification, the partial size of all aggregates come out from first sieve apparatus 4 can be allowed to be able to satisfy requirement, can be controlled
Classification processing is carried out within 32mm, and by particle size.It, can be by particle size by aggregate after the screening of fine screen equipment 8
Apply to different scenes.
Since the partial size of D grades of aggregates is less than 4mm, present essentially dust state, fugitive dust is big.For this purpose, D grades of aggregates need
After mixing wet equipment 9 and mixing wet depositing dust, D grades of aggregate processing are just completed.
In order to which aggregate to be uniformly sent into fine screen equipment 8, need that material diffusion facilities 7 are arranged before fine screen equipment 8, so that step
The aggregate of rapid two primary dcreening operation and/or the aggregate of step 3 finishing shape are sent into fine screen equipment 8 through material diffusion facilities 7.So as to have
Effect avoids the fine screen equipment 8 when aggregate is less from dallying, and insufficient problem is sieved when aggregate is more.
In addition, pre-shaped equipment 3, first sieve apparatus 4, smart shaping device 5 and fine screen equipment 8 are during the work time, can produce
Fecula dirt.If not only resulting in the waste of aggregate without processing, also polluting the environment.For this purpose, one dedusting of setting is set
It is standby, for collecting pre-shaped equipment 3, first sieve apparatus 4, dust caused by smart shaping device 5 and fine screen equipment 8.Also, it collects
The dust to get up after treatment, can be used as D grades of aggregates and use.
The problem of due to arrangement installation, a bucket elevator 6 can be generally installed before material diffusion facilities 7, by aggregate from low
Place is increased to eminence, is sent into material diffusion facilities 7.
The above embodiment is only the preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
