Set, carry out material transmission by belt conveyer between neighboring devices, it is as follows to be granulated principle: feeding device is used for quantitative claim
After weight, agitated device and crushing device are uniformly mixed, crushed, first time molding is carried out, mixed powder, which follows, once to be made
It in grain device rotary course, stirs and is continuously advanced, mixed dust sprays the effect of the surface tension of hot water in atomizing spray pipe
Under, it is shaped to small-sized spherical particles；In secondary granulation device in rotary course, light of the small particle material in secondary granulation area
It mutually adsorbs, crystallize in sliding surface rotary course, be shaped to the compound fertilizer granule of normal size size；In secondary granulation device
Be passed through hot wind to be dried, the moisture of compound fertilizer granule be evaporated for the first time, guarantee compound fertilizer granule without gluing glutinous effect,
Dust Capacity during this is also most；Compound fertilizer granule is rotatably cooled down in a cooling device, the process
Dust Capacity is equally relatively more, distinguishes by a screening plant to powdered and particle, subsequently into secondary cooling apparatus
Interior carry out secondary cooling, Dust Capacity is less during being rotationally advancing in secondary cooling apparatus, but the present invention passes through two
Ventilation duct is set between secondary cooling device and a cooling device, a small amount of dust in secondary cooling apparatus is collected again
And settle, the air quality of processing workshop is effectively ensured；
The present invention by being sufficiently stirred and crushing to base material, successively by molding twice, primary cooling, primary screening,
Ratio of briquetting has been effectively ensured in secondary cooling, regrading, and the cleanliness on compound fertilizer granule surface after molding is high, Dust Capacity is few,
It prevents from gluing glutinous problem.
2. the present invention is in feeding device, agitating device, crushing device, a prilling granulator, a screening plant, secondary sieve
Cleaning shaft is respectively provided on separating device, bag-type dust collector is arranged in the tail end of cleaning shaft, to a small amount of of above-mentioned multiple working positions
Dust carries out dust and dedusting；
Due to secondary granulation device, a cooling device, secondary cooling apparatus be rotary structure, diameter be usually two meters with
On, it can be generated in rotary course in larger amount of dust, the especially baking zone and primary cooling procedure of secondary granulation device,
The Dust Capacity that fertiliser granulates molding and cooling process generate is most, and for above three working position, the present invention uses the first weight

Sealing room be connected to by the second underground air duct with outdoor, the second underground air duct the first exhaust fan of setting；Wind with dust exists
Under the barrier effect of lower retaining wall and top retaining wall, the ground of expansion chamber is automatically fallen in by its own gravity, dust removing effects are significant, no
Only have the characteristics that construction cost is low, and can increase and the dust on ground is collected, the convenience of secondary use；It need to point out
, it is 3-5 that each gravity settling chamber, which is arranged side by side, and dust removing effects are more preferably；
The present invention simultaneously carries out comprehensive control to the dust in forming process, station especially big to Dust Capacity targetedly into
Row dedusting avoids the pollution to environment, while reducing corrosion of the dust to the steel equipment in working environment, delays and sets
Standby service life.
3. the primary rotation silo that is granulated is arranged for the front is high and the back is low, and circumferentially uniform in the primary inner wall for being granulated rotation silo
It is arranged multiple first and raises plate, the design of this structure can makes misty hot water contact with mixed dust not only conducive to the forward of material
More sufficiently, guarantee a balling ratio.
It is arranged 4. secondary granulation rotates silo for the front is high and the back is low, promotes the inner wall in area that multiple pushing plates are set, pushing plate
Spatial position is intersected with the axis of secondary granulation rotation silo, and the material that the design of this structure is conducive to inlet quickly moves ahead, and is prevented
Only occur the phenomenon that channel blockage；The inner wall in drying forming area circumferentially arranged multiple second raises plate, and second raises the extension side of plate
To rotating with secondary granulation, the axis of silo is parallel, and second raises setting multiple openings in interval on plate, and adjacent second raises between plate
Opening is staggered, this structure design, can make secondary granulation rotation silo in granule materials during raising up with heat
Air comes into full contact with, and guarantees the abundant drying of compound fertilizer granule.
It is arranged 5. primary cooling rotation silo is that the front is high and the back is low, the second outlet air is set in the front end of primary cooling rotation silo
The second gravity settling chamber is arranged in the other end of pipeline, the second wind pipe, carries out weight to the dust in primary cooling rotation silo
Power sedimentation, while the second hot air pipe, the other end of the second hot air pipe and the first weight are set in the rear end of primary cooling rotation silo
