Double screw feeding valve port packing machine is suitable for valve pocket packaging of powder materials. The advantages are small dust and high precision. Representative materials such as precipitated silica (silica), matting powder, nano light calcium carbonate, modified ultra-fine talc powder, stabilizer, flame retardant, lubricant, various pigments, active modified powder, etc.
Weighing range: 10-50kg
Packaging speed: 1-4 bags / min (determined according to the characteristics of packaging materials and different packaging bags)
Measurement accuracy: ± 0.1-0.4%
Applicable voltage: ac22ov-440v 50 / 60Hz three-phase four wire (customers need to provide local voltage level and frequency)
Gas source requirements: pressure is 0.4-0.8mpa, dry compressed air, total air consumption is 0.2m3/min
Applicable environment: altitude ≤ 2000m, environmental humidity ≤ 95% (no condensation), service temperature 0 ℃ - 50 ℃, design storage temperature - 20 ℃ - 70 ℃
In MDO series packaging machines, the materials enter the buffer bin of the packaging machine from the finished product warehouse. The materials are homogenized by the homogenization mixing system. The materials are compressed and fed by unequal distance and cone type spiral. The gas in the powder is discharged by physical extrusion with the difference speed of two screws. When the predetermined compression ratio is reached, the pressure valve opens and enters the feeding screw, When the filling weight reaches the preset quantitative value, the packaging machine stops feeding, and the packing bag is removed manually to complete the single bag packaging. The weighing instrument of MDO packaging machine can choose gross weight / net weight packaging.
