Abstract
The invention discloses a granulation method capable of continuously balling twice, and belongs to a granulation method in the fields of chemical engineering and metallurgy. The granulation method mainly comprises the following steps: (1) granulating once, carrying out primary granulation on a raw material through a disk granulating machine or a roller granulating machine; (2) carrying out secondary granulation, carrying out granulation on the material obtained from the step (1) through a granulating and drying all-in-one machine again; (3) cooling, cooling the material obtained from the step (2) through a cooling machine; and (4) screening, screening the material obtained from the step (3) through a screening machine, so as to obtain the material of which the granularity is 1.1-5.5cm. According to the granulation method, the yield of the material is greatly improved; the material is relatively stable to ball and not easy to break; the returning charge amount is reduced; and the production cost is reduced; and the granulation method is mainly applied to material granulation in the fields such as chemical engineering, metallurgy and mine.
Description
Technical field
The invention belongs to a kind of prilling process in chemical industry and field of metallurgy, specifically, particularly relate to a kind of prilling process of twice Continuous globing.
Background technology
At present, in chemical industry, metallurgy and field, mine, for by a kind of or more than one material when granulation, the prilling process usually adopted completes in granulating disc or roller pelletizer.It is that material balling ratio is lower that this prilling process exists a common problem, and returning charge amount is more, and facility investment is large, and occupation area of equipment is wide, and running cost is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, a kind of prilling process of twice Continuous globing is provided, it greatly improves the output of material, make material balling-up more stable, not easily broken, and while reducing returning charge amount, reduce production cost.
The prilling process of twice described Continuous globing, comprises the following steps:
1) granulation: material is carried out a granulation by granulating disc or roller pelletizer;
2) secondary granulation: the material that step (1) obtains is carried out granulation again by granulating dry integrated machine;
3) cool: the material that step (2) obtains is cooled by cooler;
4) sieve: the material that step (3) obtains is sieved by sieve apparatus, obtains the material that granularity is 1.1-5.5cm.
Wherein, the granularity that step (4) obtains is less than the material of 1.1cm, will again pass through step (1) and carry out granulation, cooling and screening to step (4), until obtain the material that granularity is 1.1-5.5cm.
Wherein, the granularity that step (4) obtains is greater than the material of 5.5cm, after being pulverized by pulverizer, again carry out granulation, cooling and screening to step (4), until obtain the material that granularity is 1.1-5.5cm by step (1).
Further, auxiliary agent is added in described step (2).
Compared with prior art, the invention has the beneficial effects as follows:
1, the inventive method is simple, easy to use, by twice granulation, and according to the performance of desired product, add different auxiliary agents, thus improve balling ratio and the product production of material, make material balling-up more stable, not easily broken, and while reducing returning charge amount, reduce production cost;
2, the inventive method is by original three kinds of equipment, and multiple-unit operates, and replaces with two unit operations, saves facility investment, decrease the floor space of equipment, reduce production cost.

Fig. 2 is the structural representation of granulating dry integrated machine.
In figure, 1, auxiliary agent pipe; 2, vapour pipe; 3, cylinder; 4, baffle plate; 5, material outlet; 6, material inlet.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
Embodiment 1
1) granulation: the material after metering is carried out a granulation by granulating disc;
2) secondary granulation: the material that step (1) obtains is carried out granulation again by granulating dry integrated machine, and according to the performance of desired product, auxiliary agent add metering in granulating dry integrated machine after, the ratio of material and auxiliary agent is 100:5, as need be promoted particle balling preparation rate and increasing granule strength, the auxiliary agent selected is the mixture of wilkinite or wilkinite and bauxitic clay;
3) cool: material step (2) obtained is by cooling by cooler;
4) sieve: the material that step (3) obtains is sieved by sieve apparatus, metering packing is carried out to the material that granularity is 1.1-5.5cm.
5) granularity obtained in step (4) is less than to the material of 1.1cm, again carries out granulation, cooling and screening to step (4), until obtain the material that granularity is 1.1-5.5cm by step (1).
6) granularity obtained step (4) is greater than the material of 5.5cm, after being pulverized by pulverizer, again carry out granulation, cooling and screening to step (4), until obtain the material that granularity is 1.1-5.5cm by step (1).
As shown in Figure 2, described granulating dry integrated machine comprises cylinder 3, and cylinder 3 tail down is tilted, and cylinder 3 inner top is provided with baffle plate 4, and the front end of baffle plate 4 is provided with vapour pipe 2 and auxiliary agent pipe 1, and vapour pipe 2 and auxiliary agent pipe 1 are equipped with aperture; Baffle plate 4 is positioned at 1/6-1/4 place of cylinder 3; The obliquity of cylinder 3 is 1:(30-50).
As Fig. 1, shown in Fig. 2, during work, granulating disc, granulating dry integrated machine, cooler, sieve apparatus connects respectively by rotary conveyor, when granulating disc material out sends into granulating dry integrated machine by rotary conveyor, by auxiliary agent pipe 1 and vapour pipe 2 intermittent unlatching and closedown respectively, auxiliary agent and material react in granulating cylindrical shell, the response situation of material and auxiliary agent is observed by material inlet 6, to control the fountain height of auxiliary agent pipe 1 better, cylinder 3 is in rotation process, material moves to cylinder 3 rear, and under the effect of warm air in vapour pipe 2, realize drying operation, dried material is discharged by material outlet 5, enter after cooler and sieve apparatus carry out cooling and sieve successively, material is carried out metering packing, owing to adding auxiliary agent, the balling-up of material is more stable, not easily broken, qualification rate promotes greatly.
