Principle of work of the present utility model is:

1) sets pressure relief valve 12, open the aluminium powder input valve 11 of vibration mill 1, the aluminium powder of determining specification, weight through aluminium powder input hopper 13 vibration mill 1 of packing into, is closed aluminium powder input valve 11; Open the liquid nitrogen input valve 10 on the vibration mill 1, behind the solid-liquid ratio input liquid nitrogen of setting, close liquid nitrogen input valve 10; According to the grinding technics parameter of going into to grind the aluminium powder specification, determine vibration mill 1 milling time, Vibration on Start-up mill 1 begins to grind;

2) after milling time reaches, stopping vibration mill 1 grinds, open vibration mill discharge port valve 14 and the transfer lime valve 15 that enters vibration mill 1, ejector priming 8 is the flake aluminum ground in the vibration mill 1 and the mixture of liquid nitrogen, import vortrap 3 at a high speed, the abrading-ball strainer 22 on the vibration mill 1 is stayed 1 li of vibration mill with abrading-ball strainer 22; Sometimes need to open liquid nitrogen input valve 10 in the process, in vibration mill 1, flow into liquid nitrogen to keep flow wash to flake aluminum.

3) enter the flake aluminum of vortrap 3 and the mixture of liquid nitrogen, be divided into part that reaches fineness and the part that does not reach fineness according to the flake aluminum partition size of setting by eddy flow, the part that does not reach fineness flows back to vibration mill 1 through transport pipe 9, can participate in next time and grind; Reach the part of fineness,, enter in the solid-liquid separation strainer 4 through transport pipe 9;

4) in solid-liquid separation strainer 4, the mixture of flake aluminum and liquid nitrogen upwards separates liquid nitrogen through filter screen 16, and flake aluminum and a small amount of unsegregated liquid nitrogen are stayed solid-liquid filter 4 bottoms; It is isolated in liquid nitrogen feedback pipeline 17 flows back to liquid nitrogen container 2; After liquid nitrogen circulation in vibration mill 1 finishes the flake aluminum classification, stop pump 8, close liquid nitrogen input valve 10, vibration mill discharge port valve 14 and pipeline valve 15, liquid measure in detecting vibration mill 1 and contain admittedly after, determine the aluminium powder and the amount of liquid nitrogen of interpolation in vibration mill 1, repetitive process two begins to continue to grind;

5) in process two to the operation of process five, liquid nitrogen meeting generating gasification causes gas generation, increased pressure in vibration mill 1, vortrap 3, the solid-liquid separation strainer 4, after pressure reaches 5MPa, pressure relief valve 12 can be opened and discharge the nitrogen pressure release, and pressure release valve 12 cut out automatically after pressure was reduced to setting pressure;

Open strainer discharge port valve 18, the flake aluminum of solid-liquid separation strainer 4 bottoms and a spot of liquid nitrogen mixture are put into the stirred vessel 5 of normal temperature and pressure, close strainer discharge port valve 18; According to the flake aluminum amount in the stirred vessel 5, open solvent tank output valve 20, auxiliary tank output valve 21 respectively, solvent, the auxiliary agent in solvent tank 6 and the auxiliary tank 7, proportionally import stirred vessel 5 and begin to stir the generation aluminium-silver slurry; Liquid nitrogen gasification raises stirred vessel 5 internal pressures at normal temperatures and pressures, and nitrogen is discharged through pressure relief valve 12; In the liquid nitrogen back sampling Detection index that is gasified totally, not up to standard suitably add flake aluminum again or the solvent auxiliary agent is adjusted, evenly stir and touch the mark to flake aluminum and solvent auxiliary agent, promptly become qualified aluminium-silver slurry product; Open aluminium-silver slurry discharging valve 19, aluminium-silver slurry is put into packing material.
