Blood pressure lowering, after cushion chamber and booster cavity are depressurized to-60～-80pa, piston is again adjacent to granulation groove, until booster cavity boosts to mark
Quasi-atmospheric pressure, then granulation groove carries out secondary extrusion granulation.
The method of this employing piston, it is possible to increase the shift motion of piston, thus increase the boosting of booster cavity or blood pressure lowering
The upper limit or lower limit, thus effectively ensure the ejection of elastic, it is ensured that anticlogging feasibility.
Further, its obstruction-proof method is:
Under the elastic force effect of seal closure, booster cavity is under the negative pressure state being in-10～-20pa all the time, when granulation groove squeezes
After compacting grain completes, this granulation groove to specifying position, is arranged on the extruding wheel extruding granulation groove of this appointment position with barrel body rotation
Making booster cavity boost to 10-15pa, in booster cavity boost process, elastic deforms and releases the material of residual in granulation groove
Grain；Postponing when granulation groove departs from this specific bit, booster cavity reverts to negative pressure state under the elastic force effect of seal closure.
The method, structure uses simply, is easy to maintenance and operation, the beneficially replacement of structure, the most also can realize pelletizing
The anticlogging effect of groove.
Further, the sidewall of granulation groove is followed successively by basic unit, high-temperature-resistant layer and non-sticking lining from the inside to the outside；High temperature resistant
Layer is made up of the material of following weight portion: 35 parts of tungsten carbides, 6 parts of silicon dioxide, 4 parts of quartz, 7 parts of aluminium sesquioxide, 9 parts of carbonizations
Barium, 8 parts of scorodites, 1 part of wulfenite, 3 parts of diadusts；Non-sticking lining is made up of the material of following weight portion: 30 parts of Teflons
Dragon, 3.3 parts of Ketohexamethylene, 5 parts of nanometer silicon carbides, 7 parts of spodumenes, 1 part of Barium monoxide, 5 parts of magnesium oxide, 1 part of quartz, 0.4 part of titanium valve,
2 parts of aqueous phenoxy resins, 1 part of petalite, 1.5 parts of polysiloxanes, 0.6 part of nano-aluminium oxide, 0.1 part of Kaolin.
