Abstract
The utility model discloses a processing micron order superfine powder's clash formula fluidized bed jet mill, it includes feeding device, fluid energy mill, malleation turbine grader, powder collector and air supply, and characterized in that concatenates a malleation turbine grader between fluid energy mill and powder collector, compares with prior art, the utility model discloses a powder dispersibility is good, and reinforced even, the classification quality after the processing can obviously be improved.
Description
The utility model relates to a kind of airflow milling, especially a kind of collision type fluidized bed jet mill.
The collision type fluidized bed jet mill is extensive use of by vast industrial and mining enterprises.It is the equipment that is used for processing the micron-class superfine micro mist.Its operation principle is that gases at high pressure are accelerated into supersonic airstream by nozzle, injects head-on collision and pulverizes the district, makes fluidization of material.Material is accelerated under the huge kinetic energy effect of high velocity air, in each nozzle intersection impact takes place, thereby reaches the pulverizing purpose.Pulverized material is transported to graded region with air-flow.In graded region, powder is carried out classification by the turbine type clasfficiator.Material after the classification is collected by gatherer.
But owing to the requirement of every profession and trade to powder product improves constantly.The powder that airflow milling is processed can not satisfy powder user's requirement fully.So classification becomes the first-class technical problem that powder producer is faced once more.
Powder is carried out classification both at home and abroad at present and often adopt dry classification.Dry classification mainly adopts the negative pressure turbine grading plant to carry out work.Therefore exist: technical parameters such as (1) flow field, pressure can't be guaranteed.(2) powder is dispersed bad.(3) can't evenly feed in raw material.
The purpose of this utility model, promptly the defective at above-mentioned technology provides a kind of collision type fluidized bed jet mill that improves the classification quality.It can directly obtain the better powder product of size distribution from airflow milling.
The purpose of this utility model is achieved in that the malleation turbine classifier of connecting in the middle of said flow pulverizer and powder collector, thereby has solved the technical barrier of existing dry classification.
The utility model makes each the particle outer surface parcel one deck air film from the material that airslide disintegrating mill is pulverized out owing to adopt malleation turbine clasfficiator to carry out classification.Cause intergranular affine probability to significantly reduce, therefore better dispersed.And technical parameters such as the flow of malleation turbine classifier and pressure are controlled easily, and are reinforced also stable.Thereby make the classification quality be able to obvious improvement.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model collision type fluidized bed jet mill.
Fig. 2 is the structural representation of the malleation turbine classifier among Fig. 1.
As shown in Figure 1, the utility model comprises feeding device 1, airslide disintegrating mill 2, pulverizes gatherer 4 and source of the gas 5 compositions.Between airslide disintegrating mill 2 and powder collector 4, be connected in series the malleation turbine classifier 3 of a vertical installation.
As shown in Figure 2, the malleation turbine classifier is formed by malleation turbine clasfficiator 7, discharging opening 8, feeding port 6, waste material bucket 9 and with the shell 10 that they fuse.Shell between turbine clasfficiator and feeding port is made up big and down small trumpet type cylindrical shell 11.
When the utility model used, source of the gas 5 (present embodiment is a compressor) produced supersonic airstream with the nozzle of Compressed Gas in airslide disintegrating mill 2.This air-flow quickens the material that feeding device 1 enters in the pulverizer 2, produces collision in each nozzle intersection.Material is pulverized, material after the pulverizing is delivered to malleation turbine classifier 3 with the malleation air-flow, material particles rises with flow spiral under the effect of the turbine clasfficiator 7 that rotates at a high speed on grader top, particle diameter larger particles in the powder granule is owing under the comprehensive function of deadweight and centrifugal force, drop in the waste material bucket 9.And be finished product by the gatherer collection after the classified device sorting of the material of particle diameter smaller particles (meeting product requirement).
Claims (4)
1, a kind of collision type fluidized bed jet mill.It comprises feeding device, airslide disintegrating mill, and powder collector and source of the gas is characterized in that being connected in series a malleation turbine classifier between airslide disintegrating mill and the powder collector.
